The results could not be more encouraging, the scientists found the largest site of herbivores dinosaur eggs on record. The place is something of a sanctuary at a certain time of year legion of dinosaurs met with the ceremony of laying their eggs on the sandy side of larger streams and rivers.
Some of the fossilized eggs contain embryos of dinosaurs, and there are fossilized skin against egg-skin. There is also an egg that has the skull and teeth of the creature ever born.

Aucilla River Page-Ladson prehistory site
Location coordinates:
Flordia Museum of Natural History at the University of Flordia
Wikipedia
The lowest strata in Page-Ladson is late Pleistocene. In includes mastodon, mammoth, horse and ground sloth, palaeolama bones and "straw mats" of chopped vegetation (leaves, bark and wood) of relatively uniform length. The length of the chopped vegetation is consistent with the spacing between cusps on mastodon teeth, and the "straw mats" have been interpreted as equivalent to the layers of trampledelephant dung found around water holes in Africa. Elephant steroids have been identified in the "digesta" deposits at Page-Ladson and Latvis-Simpson (a 32,000-year-old mastodon site farther south in the Aucilla). Some of the bones from this level show apparent human-made cut marks, particularly a complete mastodon tusk. Ivory spear points (often called "foreshafts") are found more frequently in the Aucilla River than everywhere else in North America combined. Samples from the "straw mat" level have yielded radiocarbon dates from 13,130 +/- 200 to 11,770 +/- 90 years Before Present. The "straw mat" level is covered by a layer of mud that did not contain any bones of extinct animals.[11]

Austin Chalk

Beecher's Trilobite Bed
Beecher's Trilobite Bed is a Konservat-Lagerstätte of Late Ordovician (Caradoc) age located within the Frankfort Shale in Cleveland's Glen, Oneida County, New York, USA.[1][2] Only 3-4 centimeters thick, Beecher's Trilobite Bed has yielded numerous exceptionally preserved trilobites with the ventral anatomy and soft tissue intact, the soft tissue preserved by pyritereplacement.[2][3] Pyritisation allows the use of X-rays to study fine detail of preserved soft body parts still within the host rock.[4][5]

Bone Cabin Quarry (Bluff Fossil Cabin Museum)
Wikipedia (http://en.wikipedia.org/wiki/Bone_Cabin_Quarry)
Bone Cabin Quarry lies approximately fifteen miles north of Laramie, Wyomingnear historic Como Bluff. During the summer of 1897 Walter W. Granger, a paleontologist from the American Museum of Natural History, came upon a hillside littered with Jurassic period dinosaur bone fragments. Nearby was a sheepherder's cabin built entirely out of fossil bones, hence the name "Bone Cabin Quarry." After Granger's discovery in late August 1897, the quarry was kept secret until the summer of 1898, when the manpower could be amassed to undertake a full-scale excavation. Bone Cabin Quarry was excavated from 1898 until 1905, when the productivity of specimens thinned. Some of the dinosaurs found at the Bone Cabin Quarry include Stegosaurus, Allosaurus and Apatosaurus.

Bromide Formation
Location coordinates: ogs.ou.edu
Wikipedia (http://en.wikipedia.org/wiki/Bromide_Formation)
Fossils have been found in the Bromide Formation of green algae, sponges, corals, graptolites, lampshells, moss animals, trilobites, clam shrimps, molluscs, several groups of echinoderms, and teeth of jawless fish. The animals we know from the fossil record from many well-known locations (including the Bromide Formation) can be viewed at a website that several paleontological institutions contributed to.[9]

Brule Formation
Wikipedia (http://en.wikipedia.org/wiki/Brule_Formation)
The Brule Formation was deposited between 34 to 30 million years ago, roughly the Rupelian (Oligocene).[2] It is a sequence of fine grained clastic rocks (claystones, mudstones, siltstones) interbeded with freshwater carbonates, volcanic ash (tuff), and sandstone.[1]
The sandstones layers, which are up to 3 m thick, can contain mammalian fossils (e.g. the Fitterer bed). The most important fossils sites are:[1]
- Fitterer Ranch
- Obritsch Ranch
- Little Badlands in Stark County
- Chalky Buttes (including White Butte) in Slope County

Burgess Shale Formation
Wikipedia (http://en.wikipedia.org/wiki/Burgess_Shale)
The Burgess Shale Formation, located in the Canadian Rockies of British Columbia, is one of the world's most celebrated fossil fields.[2] It is famous for the exceptional preservation of the soft parts of its fossils. At505 million years (Middle Cambrian) old,[3] it is one of the earliest fossil beds containing soft-part imprints.

Cabin Peak, Denali National Park, Alaska
Huffington Post
Huge Trove Of Dinosaur Footprints Discovered In National Park. The evidence emerging from the Denali hadrosaur tracks show babies and juvenile dinosaurs living in Alaska during the summer. The juveniles probably couldn't endure a long migration, so the tracks suggest the dinosaurs spent their entire lives in the Arctic, rather than migrating from somewhere else, the researchers said.

Candeleros Formation
Wikipedia (http://en.wikipedia.org/wiki/Candeleros_Formation)
The Candeleros Formation has a very diverse fossil fauna, including:
- fish
- frogs
- Iguanodonts

- an alvarezsaurid theropod (Alnashetri)
- a basal coelurosaurian (Bicentenaria)
- cladotherian mammals

Calvert Cliffs State Park
The Calvert Formation is notable for its plentiful fossil shark teeth. Especially popular among "rockhounds" are those from giants such as Carcharocles and the famous Megalodon (which is often included in Carcharocles).
The ancestral baleen whale Eobalaenoptera harrisoni and the merganser Mergus miscellus were described from the Virginian part of the formation. From the uppermost layer, deposited 15-14 Ma, they represent the oldest known member of their family and genus, respectively. Some remains of a prehistoric loon (Gavia) from the lowermost parts of the Calvert Formation, dating back nearly 18 Ma, are the oldest records of that genus from North America, and among of the oldest worldwide.

Cerrejón Formation
Wikipedia (http://en.wikipedia.org/wiki/Cerrej%C3%B3n_Formation)
Remains of the giant boid Titanoboa cerrejonensis have been found from a gray claystone layer underlying Coal Seam 90 in the Cerrejón mine. Titanoboa is the largest known snake to have ever existed, reaching an estimated length of 13 metres (43 ft). Eunectes, the anaconda, is likely to be a close living analogue ofTitanoboa.[5]
A dyrosaurid crocodylomorph called Cerrejonisuchus improcerus was described in 2010 from the Cerrejón Formation in the same layer as Titanoboa. It was a small dyrosaurid, and had the shortest snout length relative to its skull length of any dyrosaurid.

Cleveland-Lloyd Dinosaur Quarry
The Cleveland-Lloyd Dinosaur Quarry, located in The San Rafael Swell, near Cleveland, Utah, contains the densest concentration of Jurassic dinosaur fossils ever found. Well over 15,000 bones have been excavated from this Jurassic "predator trap" and there are many thousands more awaiting excavation and study. It was designated a National Natural Landmark in October 1965.[1]

Cerro del Pueblo Formation
Location coordinates: The American Journal of Botany (http://www.amjbot.org/content/95/1/77.full), Phytolaccaceae infructescence from Cerro del Pueblo Formation, Upper Cretaceous (late Campanian), Coahuila, Mexico
Wikipedia (http://en.wikipedia.org/wiki/Cerro_del_Pueblo_Formation)
The Cerro del Pueblo Formation is a geological formation in Coahuila, Mexico whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.[1] The formation has been dated to between 72.5 Ma and 71.4 million years old.[2]

Chazy Reef Formation (Isle La Motte)
Wikipedia (http://en.wikipedia.org/wiki/Chazy_Formation)
The formation is named for the small town of Chazy, New York, where the reef was noted by James Hall in Palaeontology of New York (vol. I, 1847) and the fossils first studied by the Canadian paleontologist Elkanah Billings (1858, 1859).[2] The reef extends from Tennessee to Quebec[3] andNewfoundland, but its most easily studied outcropping is at Goodsell Ridge, Isle La Motte, the northernmost island in Lake Champlain; there, gentle uplift has tilted the sediments: the bedding planes now dip slightly to the north, revealing sequences of horizons in exposed rock. The black limestone of Isle La Motte takes a polish, revealing the white "bird's-eye"[4] markings of embedded fossil shells, notably the spirals formed by sliced gastropodshells. Rock of the Chazy Formation was quarried from the nineteenth century at the Fisk Quarry, Isle La Motte, the oldest quarry in Vermont.[5]

Chuckanut Formation
Wikipedia (http://en.wikipedia.org/wiki/Chuckanut_Formation#Fossils)
Various plant and animal fossils have been found in the Chuckanut Formation. A fossil turtle shell was recovered from the formation at Clark Point in 1960. The specimen was held in the private collection of the finders until 1981 when it was examined at Western Washington University and identified as an indeterminate member of the Testudinoidea superfamily. Reexamination of the fossil in 2000 showed specimen to belong to the Trionychidaefamily of soft shelled turtles.[13]
Eocene fossil trackways are found in the Chuckanut Formation, composed of both birds[14] and animals, including mammals and some turtle tracks.[15] It is thought that the Chuckanut Formation shoreline was of riverine environments combined with a large scale "bedding plane" of material deposition. Four deposition or track sites are known.[16]

Como Bluff
Wikipedia (http://en.wikipedia.org/wiki/Como_Bluff)
Three geological formations, the Sundance, the Morrison, and the Cloverly Formations, containing fossil remains from the Late Jurassic of the Mesozoic Era are exposed. Nineteenth century paleontologists discovered many well-preserved specimens of dinosaurs, as well as mammals, turtles, crocodilians, and fish from the Morrison Formation. Because of this, Como Bluff is considered to be one of the major sites for the early discovery of dinosaur remains. Among the species discovered is the only known specimen ofCoelurus. Significant discoveries were made in 22 different areas scattered along the entire length of the ridge. It is included on the National Register of Historic Places as well as the National Natural Landmark list.

Coon Creek Formation
Wikipedia (http://en.wikipedia.org/wiki/Coon_Creek_Formation#Fossils)
The clay in the sediment at Coon Creek sealed off the fragile fossils from the corrosive action of water and the hard parts of the clams, snails, crabs, and shrimps were well preserved. Occasionally the bones of vertebrates are found, as well as the cartilaginous vertebrae of sharks. Fish scales and plant leaves are sometimes found as well (Wade 1926).

Cueva del Milodón Natural Monument
(http://en.wikipedia.org/wiki/Mylodon_Cave)
Investigations determined the survival of the Milodon until about 5,000 years ago and confirmed the existence of other animals, such as the "Dwarf Horse" Hippidion, the saber-toothed cat Smilodon and the litoptern Macrauchenia[4]
Diverse elements of human habitation are found[5] at Cueva del Milodón including fire-fractured rock, lithic tools and human remains. Human habitation at Cueva del Milodón is dated as early as 6000 BC.[6]

Decorah Shale
Wikipedia (http://en.wikipedia.org/wiki/Decorah_Shale)
The Decorah Shale is a fossiliferous shale that makes up the lower most formation in the Galena Group. The Decorah lies above the Platteville Limestone and below the Galena Limestone in the sedimentary sequence that formed from the shallow sea that covered central North America duringOrdovician Time.
Where it crops out in the Upper Midwest, especially in the Twin Cities, the Decorah is a popular place for amateur fossil collecting. It contains trilobites, brachiopods, horn corals, gastropods,crinoids, and large numbers of bryozoans.[1] Cephalopods may also be found in the lower layers of the Decorah Shale.

Dinosaur Ridge
Wikipedia (http://en.wikipedia.org/wiki/Dinosaur_Ridge)
Dinosaur Ridge is part of the Morrison Fossil Area National Natural Landmark located in Morrison, Colorado, just west of Denver.
The Dinosaur Ridge area is one of the world's most famous dinosaur fossil localities. In 1877, some of the best-known dinosaurs were found here, including Apatosaurus,Diplodocus, Stegosaurus, and Allosaurus. In 1973, the area was recognized for its uniqueness as well as its historical and scientific significance when it was designated the Morrison Fossil Area National Natural Landmark by the National Park Service. In 1989, the Friends of Dinosaur Ridge formed to address increasing concerns regarding the preservation of the site and to offer educational programs on the area's resources.

Demopolis Chalk Formation
Wikipedia (http://en.wikipedia.org/wiki/Demopolis_Chalk_Formation)
The Demopolis Chalk Formation is a geological formation in North America, within the U.S.states of Alabama, Mississippi, and Tennessee. The chalk was formed by pelagic sedimentsdeposited along the eastern edge of the Mississippi embayment during the middle Campanianstage of the Late Cretaceous.[1] It is a unit of the Selma Group and consists of the upper Bluffport Marl Member and a lower unnamed member.[2] Dinosaur and mosasaur remains are among the fossils that have been recovered from the Demopolis Chalk Formation.[2][3]

Dinosaur Provincial Park
Wikipedia (http://en.wikipedia.org/wiki/Dinosaur_Provincial_Park)
Dinosaur Provincial Park preserves an extraordinarily diverse group of freshwater vertebrates. Fish include sharks, rays (such as the durophage Myledaphus), paddlefish, bowfins, gars, andteleosts. Amphibians include frogs, salamanders, and the extinct albanerpetontids. Reptiles include lizards (such as the large monitor Paleosaniwa), a wide range of turtles, crocodilians, and the fish-eating Champsosaurus. Mammal fossils from the park are relatively rare and consist of isolated teeth, fragmentary jaws with teeth, and tooth fragments from mouse-sized and shrew-sized animals. They include representatives of placental, marsupial, andmultituberculate mammals.[2]
Plant fossils from the park and surrounding area include fern fronds; foliage and wood of taxodiaceous and cupressaceous conifers; and leaves of Ginkgo, Cercidiphyllum, Platanus, aPistia-like aquatic plant, and others.[3] A rich assemblage of fossil pollen and spores has also been described.[4]

Dinosaur State Park
Dinosaur State Park is one of the largest dinosaur track sites in North America. The tracks are from the early Jurassic period and were made over 200 million years ago by a carnivorous dinosaur similar to Dilophosaurus. At present, 500 tracks are enclosed within a 55,000-square-foot (5,100 m2) geodesic dome; the remaining 1,500 are buried for preservation. The park's in-site tracks are Eubrontes, named by Edward Hitchcock, pioneering student of fossilized tracks and one of America's first geologists. The tracks range from 10 to 16 inches (410 mm) in length and are spaced 3.5 to 4.5 feet (1.4 m) apart. The exhibit center also includes rock slabs with other Connecticut Valley fossil tracks, including large four-toed Otozoum tracks with clearly visible skin impressions.[4]

Driftwood Canyon Provincial Park
The Driftwood Canyon fossil beds are best known for the abundant and well preserved insect and fish fossils (Amia, Amyzon, and Eosalmo).[11] The insects are particularly diverse and well preserved, and include water striders(Gerridae), aphids (Aphididae), leaf hoppers (Cicadellidae), green lacewings (Neuroptera), spittle bugs (Cercopidae), march flies (Bibionidae), scorpionflies (Mecoptera), fungus gnats (Mycetophilidae), snout beetles (Curculionidae), and ichneumon wasps.

Ellisdale Fossil Site
Megafossils of at least three different types of plants have been found at the site: Liriodendron, Metasequoia, and Picea. In addition, possible remains of Mangrove roots have been found encased in siderite concretions. Amber has been found at the site occurring in small droplets, generally less than 5 millimeters in size.

Eutaw Formation
Wikipedia (http://en.wikipedia.org/wiki/Eutaw_Formation)
The Eutaw Formation is a geological formation in North America, within the U.S. states of Alabama, Georgia, and Mississippi. The strata date from the late Coniacian to the early Santonian stage of the Late Cretaceous.[1] It consists of the upper Tombigbee Sand Member and an unnamed lower member. Dinosaur, mosasaur, and pterosaur remains have been recovered from the Eutaw Formation.[2][3]

Falls of the Ohio State Park
Wikipedia (http://en.wikipedia.org/wiki/Falls_of_the_Ohio_State_Park)
The center functions as a museum with exhibits that concentrate on the natural history related to findings in the nearby fossil beds as well as the human history of the Louisville area, covering pre-settlement, early settlement, and Louisville and southern Indiana history all the way up through the 20th century.

Florissant Fossil Beds
The fossils have been preserved because of the interaction of the volcanic ash from the nearby Thirtynine Mile volcanic field with diatoms in the lake, causing an algal bloom. As the algae fell to the bottom of the lake, any plants or animals that had recently died were preserved by the algal mats.

Ghost Ranch
Wikipedia (http://en.wikipedia.org/wiki/Ghost_Ranch)
Ghost Ranch includes a famous palaeontological site preserving Triassic dinosaurs. Fossil bones were found here as early as 1885.[citation needed] In 1947 the palaeontologist Edwin H. Colbertdocumented the discovery of over a thousand well-preserved fossilized skeletons of a smallTriassic dinosaur called Coelophysis in a quarry here.[4] In 2007, fossil remains of Dromomeron romeri, one of the archaic group of animals called "basal dinosauromorphs," were found in the Hayden Quarry.[5] In April 2010, a team of scientists led by Hans-Dieter Suesof the Smithsonian Institution reported the discovery of Daemonosauruschauliodus, a basal theropod species, at Ghost Ranch.[3] Daemonosauruslived approximately 205 million years ago, during a transitional period between the oldest known dinosaurs such as Herrerasaurus, which existed during theLate Triassic period in what is now known as Argentina and Brazil, and the more advanced theropod dinosaurs.[3][6]

Glen Rose Formation
Wikipedia (http://en.wikipedia.org/wiki/Glen_Rose_Formation#Fossils)
A variety of fossils are found in the Glen Rose, more abundantly in the lower Glen Rose than the upper,[8] including numerous gastropods, clams and echinoids. Many species in the lower portion are not found in the upper portion.[14] Dinosaur tracks have been found in many localities, as well as isolated vertebrate remains. Microfossils also are present, including one of the largest foraminifera ever found.

Green River Formation
Millions of fish fossils have been collected from the area, commercial collectors operating from legal quarries on state and private land have been responsible for the majority of Green River vertebrate fossils in public and private collections all over the world. [10]

Gunflint chert
Wikipedia (http://en.wikipedia.org/wiki/Gunflint_Chert)
Stanley A. Tyler examined the area in 1953, and noted the red-colored stromatolites. He also sampled a jet-black chert layer which, when observedpetrographically, revealed some lifelike small spheres, rods and filaments less than 10 micrometres in size. Elso Barghoorn, a paleobotanist at Harvard, subsequently looked at these same samples. Barghoorn concluded that "they were indeed structurally preserved unicellular organisms."[2] In 1965, the two scientists published their finding, and named a variety of the Gunflint flora.[3] This created an academic "stampede" to explore Precambrian microfossils from similar Proterozoic environments.

Hadrosaurus Foulkii Leidy Site
Hadrosaurus Foulkii Leidy Site in Haddonfield, Camden County, New Jersey, United States, is where the first relatively complete set of dinosaurbones were discovered in 1838, and then fully excavated by William Parker Foulke in 1858. The dinosaur was later named Hadrosaurus foulkii byJoseph Leidy. The site lingered in obscurity until 1984 when a local Boy Scout from Troop 65, Christopher Brees, as part of an Eagle Scout project researched the site and generated publicity, eventually leading to the species being designated the official dinosaur of New Jersey.

Hagerman Fossil Beds
The Hagerman Horse Quarry resides near the top of the hillside of Smithsonian Hill. The hill was named from the early Smithsonian excavations of the Hagerman horse. The Hagerman horse is the first fossil representation of the genus Equus in North America.
- Hagerman horse, Equus simplicidens, formerly known as Plesippus shoshonensis
- Camelops, an extinct genus of camel that once inhabited North AmericaMany other species are also found in the fossil record, including mastodons, dirk tooth cats and bone crushing dogs (Borophaginae), as well as various species of fish, frog, vole and beaver.

Hell Creek Formation
Wikipedia (http://en.wikipedia.org/wiki/Hell_Creek_Formation)
The formation has produced impressive assemblages of invertebrates, plants, mammals, fish, reptiles (including the lizard Obamadon), and amphibians. Notable dinosaur finds include Tyrannosaurus and Triceratops. The most complete Hadrosaurid dinosaur ever found was retrieved in 2000 from the Hell Creek Formation and widely publicised in a National Geographic documentary aired in December 2007. A few bird, mammal, and pterosaur fossils have also been found. Teeth ofsharks and rays are sometimes found in the riverine Hell Creek Formation, suggesting that some of these taxa were then, as now, tolerant of fresh water.

Hilda mega-bonebed
By the conclusion of the research program, the scientists mapped the bonebeds and excavated the bonebed cataloged as H97-04.[9] They concluded that the Hilda bonebeds formed simultaneously when a herd consisting of thousands of Centrosaurus apertus drowned in a flood.[9] The researchers further speculated that some of the 17 Centrosaurus bonebeds of Dinosaur Provincial Park likely formed simultaneously in a manner analogous to the formation of the Hilda bonebeds, which the researchers estimated to be spread over 2.3 km.[9] The researchers only collected fossils and taphonomic data from the bonebed H97-04, although all the others were also examined to check the quality and number of preserved bones.[10] The research at Hilda was so complex that over ten years passed from the start of the project until David A. Eberth, Donald B. Brinkman, and Vaia Barkas published a formal description in the scientific literature.[11]

Hornerstown Formation
Wikipedia (http://en.wikipedia.org/wiki/Hornerstown_Formation)
The Hornerstown Formation is a Paleogene or latest Mesozoic geologic formation.[1] The age of these deposits have been controversial. While most fossils are of animals types known from the earliest Cenozoic era, several fossils of otherwise exclusively Cretaceous age have been found. These include remains of the shark Squalicorax, the teleost fish Enchodus, several species of ammonite, and marine lizards referred to the genusMosasaurus. Some of these remains show signs of severe abrasion and erosion, however, implying that they are probably re-worked from older deposits. Most of these fossils are restricted to the lowest point in the formation, one rich in fossils and known as the Main Fossiliferous Layer, or MFL. Other explanations for the out-of-place fossils in the MFL is that they represent a time-averaged assemblage that built up and remained unburied during a time of low sediment deposition, or that they were stirred up from deeper in the sediment and deposited together during a tsunami.[2

Huincul Formation (Plaza Huncul Museo Carmen Funes)
Wikipedia (http://en.wikipedia.org/wiki/Huincul_Formation)
Fossil bones are rarely found in the Huincul Formation. However, remains of the largest land animal known, Argentinosaurus huinculensis, were found in the Huincul Formation, and this species is named after it.[1] One of the largest predators known, Mapusaurus, has also been recovered from a bonebed in this formation.[3]
Animal fossils found in the Huincul Formation include:
- several titanosaurian sauropods (including Argentinosaurus)
- a rebbachisaurid sauropod (Cathartesaura)
- a carcharodontosaurid theropod (Mapusaurus)
- abelisauroid theropods (including Skorpiovenator and Ilokelesia)

Wikipedia (http://en.wikipedia.org/wiki/Ischigualasto_Formation)
The Ischigualasto Formation contains Late Triassic (Carnian) deposits (231.4 -225.9 million years before the present[4]), with some of the oldest known dinosaur remains, which are the world's first with regards to quality, number and importance. It is the only place in the world where nearly all of the Triassic is represented in an undisturbed sequence of rock deposits. This allows for the study of the transition between dinosaurs and ancient mammals; research is ongoing.
Rhynchosaurs and cynodonts (especially rhynchosaur Hyperodapedon and cynodont Exaeretodon[4]) are by far the predominant findings among the tetrapod fossils in the park. Dinosaur specimens comprise only 6% of the total tetrapod sample;[5] subsequent discoveries increased this number to approximately 11% of all findings.[4] Carnivorous dinosaurs are the most common terrestrial carnivores of the Ischigualasto Formation, with herrerasaurids comprising 72% of all recovered terrestrial carnivores.

Joggins Fossil Cliffs
In 1852 Lyell and Dawson made a celebrated discovery of tetrapod fossils entombed within an upright tree at Coal Mine Point. Subsequent investigations by Dawson led to the discovery of one of the most important fossils in the history of science, Hylonomus lyelli, which remains the earliest known sauropsid (reptile) in the history of life, but not oldest known amniote, the group that includes all vertebrates that can reproduce out of water.[9] In 2002, Hylonomus lyelli was named the provincial fossil of Nova Scotia. Another vital early tetrapod fossil has been found here, the earliest synapsid, Protoclepsydrops, which is actually earlier thanHylonomus.[10]p39

John Day Fossil Beds
Wikipedia (http://en.wikipedia.org/wiki/Clarno_Formation)
Fossils found in the John Day Strata include a wide variety of plants and more than 100 species of mammals, including dogs, cats, oreodonts, saber-toothed tigers, horses, camels, and rodents.[37][45] The Blue Basin and the Sheep Rock unit contain many of these same fossils, as well as turtles, opossums, and large pigs.[46] More than 60 plant species are fossilized in these strata, such ashydrangea, peas, hawthorn, and mulberry, as well as pines and many deciduous trees.[47] One of the notable plant fossils is the Metasequoia (dawn redwood), a genus thought to have gone extinct worldwide until it was discovered alive in China in the early 20th century.[48]

Judith River Formation
Wikipedia (http://en.wikipedia.org/wiki/Judith_River_Formation)
The Judith River Formation is a fossil-bearing geologic formation in Montana, and is part of the Judith River Group. It dates to the upper Cretaceous, between 80 and 75 million years ago, corresponding to the "Judithian" land vertebrate age. It was laid down during the same time period as portions of the Two Medicine Formation of Montana[1] and the Oldman Formation of Alberta.[5] It is an historically important formation, explored by early American paleontologists such as Edward Drinker Cope, who named several dinosaurs from scrappy remains found here on his 1876 expedition (such as Monoclonius). Modern work has found nearly complete skeletons of the hadrosaurid Brachylophosaurus.

Krukowski Quarry - Blackberry Hill
Location: fossilmall.com
Wikipedia (http://en.wikipedia.org/wiki/Krukowski_Quarry)
Krukowski Quarry is a sandstone quarry near Mosinee, Wisconsin. In the late Cambrian period (510 m.y.a), this area was a beach and shoreline, and the quarry is well known for abundant fossil impressions of Climactichnites, Protichnites, and beached jellyfish, Scyphozoan Medusae. Pre-Devonianevidence of this jellyfish is exceedingly rare; this location and one in New Brunswick hold the only known fossils. The fossilized tracks ofClimactichnites and Protichnites are also amongst the best preserved examples in the world. No fossilized remains of the either animal exist, making them enigmatic species. The quality and quantity of these fossil tracks in the quarry are extremely valuable to paleontologists.

La Brea Tar Pits

The La Brea Tar Pits (or Rancho La Brea Tar Pits) are a group of tar pits around which Hancock Park was formed, in urban Los Angeles. Asphaltum or tar (brea in Spanish) has seeped up from the ground in this area for tens of thousands of years. The tar is often covered with dust, leaves, or water. Over many centuries, the bones of animals that were trapped in the tar were preserved. The George C. Page Museum is dedicated to researching the tar pits and displaying specimens from the animals that died there. The La Brea Tar Pits are a registered National Natural Landmark.

Lance (Creek) Formation
Location: Book - Paleocene Flora of the Rocky Mountains and Great Plains, Issue 375, page 20, by Roland Wilbur Brown
Wikipedia (http://en.wikipedia.org/wiki/Lance_Formation)
At least tens of thousands of Late Cretaceous vertebrate remains have been recovered from the Lance Formation. Fossils ranging from microscopic elements to extensive bonebeds, with nearly complete, sometimes articulated dinosaur skeletons, have been found. Most other animals known from the formation are freshwater animals, and some are exclusively freshwater forms (for instance, frogs and salamanders). However, marine fossils are also found in the formation, suggesting that the sea was nearby. The bird fauna is mainly composed of orders still existing today.

Invertebrate fossils include bivalves,clam shrimp, insect wings (Homoptera and Coleoptera),pygocephalomorphs, and Chondrites. Vertebrate fossils include fragmentary remains of actinistians (coelacanths) andactinopterygians (tentatively identified as belonging toElonichthyidae), possible ichnofossils of acanthodians (Undichna insolentia), and numerous and well-preserved skulls and partial skeletons of mesosaurs (Stereosternum and Mesosaurus).[3]

Manuels River
Wikipedia (http://en.wikipedia.org/wiki/Manuels_River#Fossils)
Trilobites are the primary fossil remains found in the rocks of the Manuels River. These prehistoric animals lived on the seabed and left trails as they crawled around in search of food. Trilobites resemble sow bugs (commonly known as 'carpenters') or crabs and were first discovered along the river in 1874 by T.C. Weston of the Geological Survey of Canada. Complete specimens are rare, however, some have been found measuring as long as 30 cm. Many of the fossil remains are fragments of their shells discarded in a manner similar to today's lobsters.
Removing fossil specimens and rock samples is prohibited, but the Society encourages observation and provides educational tours of these wonders from our prehistoric past.

Mazon Creek fossil beds
The Field Museum
Wikipedia (http://en.wikipedia.org/wiki/Francis_Creek_Shale)
fossil beds are located in ironstone concretions, formed approximately300 million years ago in the mid-Pennsylvanian epoch of the Carboniferous period. These concretions frequently preserve both hard and soft tissues of animal and plant materials, as well as many soft-bodied organisms that do not normally fossilize. The quality, quantity and diversity of fossils in the area, known since the mid-nineteenth century, make the Mazon Creek lagerstätteimportant to paleontologists, in attempting to reconstruct the paleoecology of the sites.[3] The locality was declared a National Historic Landmark in 1997.[2][4]

McAbee Fossil Beds

Some of the fish, fauna, and spore fossils found at Miguasha are rare and ancient species. For example, Spermasposita is thought to be one of the oldest flowering plant[2] genera on Earth.[3]
Miguasha National Park is considered to be the world's greatest palaeontological record of fossils from the Devonian Period, known as the 'Age of Fishes'. Five of the six main fossil fish groups from this period (dating from 370 million years ago) can be found here. A great quantity of some of the best-preserved fossil specimens of lobe-finned fish, ancestors to the tetrapods (believed to be the first four-legged air-breathing terrestrial vertebrates), were found here.

Natural Trap Cave, WY
phys.org
(AP)—For the first time in three decades, paleontologists are about to revisit one of North America's most remarkable troves of ancient fossils: The bones of tens of thousands of animals piled at the bottom of a sinkhole-type cave.
Natural Trap Cave in Wyoming is 85 feet (25 meters) deep and almost impossible to see until you're standing right next to it. Over tens of thousands of years, many, many animals—including now-extinct mammoths, short-faced bears, American lions and American cheetahs—shared the misfortune of not noticing the 15-foot-wide (4 meters) opening until they were plunging to their deaths.
Now, the U.S. Bureau of Land Management is preparing to reopen a metal grate over the opening to offer scientists what may be their best look yet at the variety of critters that roamed the foothills of the Bighorn Mountains during the planet's last glacial period around 25,000 years ago.

The Nature Center has a display of fossils found in the area. They also rent screens and trowels for use while looking for fossils. The fossils in the exposed Navesink Formation are in the stream bed and are easily accessible from the parking lot along Middletown road. There is a display sign with pictures of the fossils likely to be found. The Conservancy asks that visitors collect from the stream bed only and not to dig into the banks which only hastens erosion. They also ask that visitors collect conservatively and that anything unusual be given to the Nature Center.[3][5]
Common fossils include Pyncnodonte mutabilis, Pyncnodonte convexa, Exogyra cancellata, Exogyra costata, Ostrea mesenterica,Agerostrea, Belemnitella americana and shark teeth. These are mostly extinct version of oysters and clams.

Some 25 species of fossil fishes are often found with stomach contents preserved, enabling paleontologists to study predator-prey relationships in this ecosystem. There are also fine examples of pterosaurs, reptiles and amphibians, invertebrates (particularly insects), and plants. Even dinosaurs are represented: a new maniraptor was described in 1996. The unusual taphonomy of the site resulted in limestone accretions that formed nodules around dead organisms, preserving even soft parts of their anatomy. In preservation, the nodules are etched away with acid, and the fossils often prepared by the transfer technique.[1]

Snowmastodon site
Wikipedia (http://en.wikipedia.org/wiki/Ziegler_Reservoir_fossil_site)
The Snowmastodon site, also known as the Snowmass Village fossil site or the Ziegler Reservoir fossil site, is a fossil excavation nearSnowmass Village, Colorado. It was discovered on October 14, 2010, when construction workers building a reservoir dam to supply water to Snowmass Village uncovered fossil bones that turned out to belong to a young female mammoth. Official fossil excavations, organized by the Denver Museum of Nature and Science under the nickname "Snowmastodon Project," began on November 2, 2010. They ended, as agreed, on July 1, 2011, so that construction work could resume. During this short period, the project unearthed 4,826 bones from 26 different Ice Agevertebrates, including mammoths, mastodons, bisons, camels, a Pleistocene horse, and the first ground sloth ever found in Colorado.
The site, once the shores of a small glacial lake, dates from the Illinoian age of the Pleistocene epoch, around 150,000 to 130,000 years ago.

Two Medicine Formation - Egg Mountain
Egg Mountain was discovered in 1977 by Marion Brandvold, owner of the Trex Agate Rock Shop in Bynum, Montana, who discovered the bones of juvenile dinosaurs at this site. It is a colonial nesting site on the Willow Creek Anticline in the Two Medicine Formation that is famous for its fossil eggs ofMaiasaura, which demonstrated for the first time that at least some dinosaurs cared for their young. The eggs were arranged in dug-out earthen nests, each nest about a parent's body length from the next, and baby dinosaurs were also found with skeletons too cartilaginous for them to walk - similar to those of altricial (helpless) baby birds. The parent(s) must then have brought food to the young, and there is plant matter in the nests that may be evidence of either this or for incubation of the eggs. Maiasaura also grew extremely fast, at rates comparable to modern birds. Skeletons of Orodromeusand skeletons and eggs of Troodon were also found at Egg Mountain.

Urumaco
Wikipedia (http://en.wikipedia.org/wiki/Urumaco)
Urumaco is a town in the state of Falcón in Venezuela. It is of world importance for its fossils. Thearid climate of the region means that the fossils are not hidden by vegetation. They were first made known to science by geologists who came across them while looking for oil (which is abundant in some parts of Venezuela). The paleontological wealth of Urumaco makes it the most fossil-rich zone of northern South America.
Stupendemys geographicus, the largest turtle ever to have existed was found here in the 1970s by researchers from Harvard University. More recently publicity has been attracted by discoveries of the giant rodent Phoberomys pattersoni from the Miocene epoch.[1]

Villavieja Formation - La Venta
The fossils occur in Middle Miocene rocks of the Villavieja Formation and La Victoria Formation. The La Venta fauna contained ancient species of animal genera and families still alive today, as well as some entirely extinct prehistoric lineages. These animals lived some 13.8 to 12million years ago in the Laventan age, which was named after La Venta. At that time, theclimate of the region was wetter than today and there was much forest of trees similar (and probably related) to the sapino (Goupia glabra) of our time.

Wannagan Creek site
Location coordinates: fossilworks.org
Wikipedia (http://en.wikipedia.org/wiki/Wannagan_Creek_site)
Many mammals are found at the site. All are small compared to modern mammals, the largest being sheep-sized. Preserved mammals include a squirrel-like primitive primate and Ptilodus; an arboreal multituberculate. The largest mammal at the site is the condylarth herbivore Phenacodus. An additional mammal fossil is Protictis, a weasel sized member of Viverridae that may have hunted on the forest floor.
Reptiles are the dominant animal type preserved at Wannagan. The largest animal (~4 meters [13 ft] in length) found at the site is the eusuchian crocodilian Borealosuchus formidabilis(formerly known as Leidyosuchus formidabilis). B. formidabilis is also thought to be the apex predator of the fauna. The second largest reptile is the champsosaur Champsosaurus gigas. C. gigas is unusual among Paleocene reptiles in that it is larger than its known Mesozoic ancestors; 3 meters (10 ft) in length versus 1.5 meters (4.5 ft) for the largest Cretaceouschampsosaurs. Reptiles as a whole decreased in size after the Cretaceous–Paleogene extinction event. Other reptiles include soft-shelled turtles, varanid lizards, a small alligatorid calledWannaganosuchus, palaeophid snakes, and the snapping turtle-like Protochelydra zangerli.

Long-Necked Sauropod Dinosaur Unearthed In Argentina (approximated)
huffingtonpost
It's not exactly small at 30 feet long (9 meters), but you might want to call this newly identified dinosaur the littlest giant.
Scientists in Argentina on Wednesday announced the discovery of the fossilized remains of a unique member of the famous long-necked, plant-munching dinosaurs known as sauropods, the largest land creatures in Earth's history.
Leinkupal lived in a semiarid environment south of a large desert, the researchers said. Its incomplete remains were found in Patagonia - a region renowned for its dinosaur finds - in 2010 and 2012 in Argentina's Neuquen province, they added.

A Gigantic, Exceptionally Complete Titanosaurian Sauropod Dinosaur from Southern Patagonia, Argentina
nature.com
Titanosaurian sauropod dinosaurs were the most diverse and abundant large-bodied herbivores in the southern continents during the final 30 million years of the Mesozoic Era. Several titanosaur species are regarded as the most massive land-living animals yet discovered; nevertheless, nearly all of these giant titanosaurs are known only from very incomplete fossils, hindering a detailed understanding of their anatomy. Here we describe a new and gigantic titanosaur, Dreadnoughtus schrani, from Upper Cretaceous sediments in southern Patagonia, Argentina. Represented by approximately 70% of the postcranial skeleton, plus craniodental remains, Dreadnoughtus is the most complete giant titanosaur yet discovered, and provides new insight into the morphology and evolutionary history of these colossal animals. Furthermore, despite its estimated mass of about 59.3 metric tons, the bone histology of the Dreadnoughtus type specimen reveals that this individual was still growing at the time of death.
