State dinosaur of Arkansas. Its generic name was in use informally even before its formal description. Arundel Formation Early Cretaceous , Albian. United States Maryland. Trinity Group Early Cretaceous , Albian. Potentially synonymous with Apatosaurus , [12] but a referred species may represent a separate taxon [13]. Moreno Formation Late Cretaceous , Maastrichtian. State dinosaur of California.

Originally named as a species of Saurolophus. Lacked the fenestrae in its frill, a feature shared only with Triceratops. United States South Dakota Utah. Similar to Diplodocus but larger and with a longer neck. Analysis of its braincase suggest it behaved like tyrannosaurids despite not being a member of that family [14].

Originally identified as a specimen of Pentaceratops. Clearwater Formation Early Cretaceous , Albian. So well preserved that several osteoderms were found in the positions they would have been in when alive.

Wapiti Formation Late Cretaceous , Campanian. Only known from juvenile remains. One specimen has been found to represent a subadult Rubeosaurus. Canada Alberta United States Montana. Possessed an enlarged ilium which supported powerful leg muscles, which it may have used to kick away predators.

Morrison Formation Late Jurassic , Kimmeridgian. United States Utah Wyoming. Popularly associated with Apatosaurus but a study found enough differences for it to be classified as a separate genus [13]. United States Colorado Utah Wyoming. United States Arizona. May have fed on tough vegetation as evidenced by extensive wear frequently exhibited on its teeth [15].

Tecovas Formation Late Triassic , Norian. Possibly synonymous with Chindesaurus. United States Colorado Wyoming. A referred specimen shows possible evidence of a keratinous beak [16].

One specimen preserves over a hundred gastroliths [17]. Known from a partial skeleton. The specific name, C. Hundreds of individuals have been preserved in a single “mega-bonebed” [18].

Although only known from a few bones, this genus is the namesake of the Ceratopsia and the Ceratopsidae. Ceratosaurus C. Chinle Formation Late Triassic , Norian. May have been a close relative of Tawa [19].

Canada Alberta United States Colorado. Niobrara Formation Late Cretaceous , Campanian. United States Kansas. United States Arizona New Mexico. Known from over a thousand specimens, making it one of the more well-known early dinosaurs.

Some referred species may belong to their own genera. Potentially an early member of the tyrannosauroid lineage [20]. Foremost Formation Late Cretaceous , Campanian. Originally described as a species of Stegoceras. Before its formal description, it had been informally referred to as the ” Proctor Lake hypsilophodont”. Chinle Formation Late Triassic , Rhaetian. Lakota Formation Early Cretaceous , Barremian.

United States South Dakota. Originally named as a species of Iguanodon. Instead of lips, it may have possessed crocodile-like scales on its snout [21].

Montana Oklahoma Wyoming. Its discovery helped researchers realize that dinosaurs were active, warm-blooded animals, kicking off the Dinosaur Renaissance.

Lance Formation Late Cretaceous , Maastrichtian. United States South Dakota Wyoming. The youngest known nodosaurid [22]. Kayenta Formation Early Jurassic , Sinemurian. Several features of its hands and feet may be adaptations for increased grip strength [23]. Had a long, thin tail that may have been used like a bullwhip [24]. Hornerstown Formation? Late Cretaceous , Maastrichtian. United States New Jersey. May be synonymous with Ornithomimus edmontonicus.

Remains of multiple growth stages have been found, including embryoes [25]. Menefee Formation Late Cretaceous , Campanian. The holotype specimen preserves skin impressions [26]. Lance Formation? Late Jurassic , Kimmeridgian? Inconsistent in phylogenetic placement, although undescribed remains could further clarify its relationships. Known from multiple well-preserved specimens, including a few “mummies”. Mooreville Chalk Late Cretaceous , Santonian. The first Appalachian hadrosaurid known from a preserved skull [27].

Unusually, its palpebral bone was mobile, allowing it to be used as an eyelid [28]. Transitional between generalized theropods and specialized therizinosaurs [29]. Canada British Columbia. Its holotype was discovered close to a railway line [30]. Has been variously described as a ceratosaurid, a tetanuran, or a close relative of Elaphrosaurus [31].

One of the smallest known ornithischians [32]. Several concentrations of fossils may suggest this species lived in herds [33]. Described as a basal hadrosauroid but may in fact be a juvenile saurolophine [34]. Originally interpreted as possessing a flat mosaic of osteoderms similar to the shields of glyptodonts. May be a chimera consisting of undiagnostic theropod bones mixed with pseudosuchian vertebrae [35]. Potentially synonymous with Stegoceras [36]. Dinosaur Park Formation , Javelina Formation?

One specimen preserves impressions of a row of pyramidal scales running along its back [37]. Woodbury Formation Late Cretaceous , Campanian. Possibly a synonym of Stegoceras [36]. United States Colorado Montana? May have been a basal diplodocoid [13]. United States Montana Wyoming. Two morphotypes of plates are known, which could be explained by sexual dimorphism [38]. Known from some osteoderms, including spikes, similar to those of Polacanthus.

Unnamed formation Late Cretaceous , Santonian. The southernmost non-hadrosaurid hadrosauroid known from North America [39]. United States Missouri North Carolina. Usually seen as synonymous with Stegosaurus but may be a separate genus due to differences in its vertebrae [40].

Only known from a few bones but can be distinguished from other genera by characters of its osteoderms. Greenland Sermersooq. Originally described as an exemplar of Plateosaurus. Its postorbital bone had a rugose texture. One study considered it to be a basal dicraeosaurid [41].

Possessed fifteen horns and horn-like structures, including eight hornlets folding down from the top of the frill. Mexico Baja California. Robustly built with particularly strengthened frontals. Possessed a hollow head crest that varied in shape between species, sexes, and ages.

Most familiarly, it was hatchet-shaped in adult male L. Potentially a chimera composed of lambeosaurine and saurolophine remains [42]. Dockum Group Late Triassic , Norian. Analysis of its teeth show it could chew like a mammal, an adaptation to eating tough, fibrous plants [43].

Has been suggested to be semi-aquatic due to its tall, narrow tail [44]. Remains of hundreds of individuals, including juveniles, eggs, and nests, have been found at a single site [45]. United States Colorado? Potentially a close relative of South America megalosauroids [46]. Had a “wing”-like projection on its squamosal bone. Teeth from Deinonychus have been mistakenly attributed to this species. One of the latest-surviving turiasaurs [47].

Described as a macronarian [48] but has since been reinterpreted as a turiasaur closely related to Mierasaurus [47]. Elsewhere, the most productive dinosaur fossil sites tend to be remote and barren areas where rock is exposed at the surface — such as the Gobi desert in China and Mongolia, and the desert regions of the midwestern United States such as Arizona, Montana and Nevada.

Here, fossils from the Late Jurassic and Late Cretaceous epochs have been collected throughout the 20th century, enabling scientists to develop a very good picture of the development of dinosaurs during this time. The hottest spot of all, however, is currently China, where over the past two decades a huge number of important discoveries have been made in the north-eastern Liaoning province. And at the end of last year, the world’s biggest deposit of dinosaur bones — an estimated 7, samples — was reported to have been found in Shandong province on China’s eastern coast; mindblowing when you consider that, in normal circumstances, there is perhaps a one-in-a-million chance that a dinosaur bone will form a fossil.

What states did dinosaurs live in. In Which States Are Dinosaur Fossils Found?

 

This is a list of dinosaurs whose remains have been recovered from North America. North America has a rich dinosaur fossil record with great diversity of dinosaurs. The earliest potential record of dinosaurs in North America comes from rare, unidentified possibly theropod footprints in the Middle-Late Triassic Pekin Formation of North Carolina. Fossils of Tawa -like dinosaurs have also been found in South America, which has important indications about paleogeography.

During the Early Jurassic Perioddinosaurs such as DilophosaurusAnchisaurusCoelophysis formerly known as Megapnosaurusand the early thyreophoran Scutellosaurus увидеть больше in North America. The latter is believed to have been the ancestor of all stegosaurs and ankylosaurs. The Middle Jurassic is the only poorly represented time period in North America, although several Middle Jurassic localities are known from Mexico.

Footprints, eggshells, teeth, and fragments of bone representing theropods, sauropods, and ornithopods have what states did dinosaurs live in found, but none of them are diagnostic to the genus level. It is notable as being the most fertile single source of dinosaur fossils in the world. The roster of dinosaurs from the Morrison is impressive. An abundance of sauropods has been found there, including ApatosaurusDiplodocusBarosaurusBrachiosaurusCamarasaurusBrontosaurus and Amphicoelias.

Three genera of stegosaurs, AlcovasaurusStegosaurus and Hesperosaurushave been found there. Finally, ornithopods found in the Morrison include CamptosaurusDryosaurusand Nanosaurus. During the Early Cretaceousnew dinosaurs evolved to replace the old ones. Sauropods were still present, but they were not as diverse as they were in the Jurassic Period.

Theropods from the Early Cretaceous of North America include dromaeosaurids such as Deinonychus and Utahraptorthe carnosaur Acrocanthosaurusand the coelurosaur Microvenator. Sauropods included AstrodonBrontomeruswhat states did dinosaurs live in Sauroposeidon.

Ornithischians were more diverse than they were in the Jurassic Period. Tenontosaurus what states did dinosaurs live in, DakotadonProtohadrosand Eolambia are some of the ornithopods that lived during this time period.

Ankylosaurs replaced their stegosaur cousins in the Cretaceous. Finally, during the Late Cretaceous Period, the greatest abundance and diversity of dinosaurs what states did dinosaurs live in all time lived in North America.

During the early part of the Late Cretaceous, the therizinosaur Nothronychus and the ceratopsian Zuniceratops lived. During the Campanian stage of the Late Cretaceous, an enormous diversity of dinosaurs is known. Theropods what states did dinosaurs live in the tyrannosaurs AlbertosaurusGorgosaurusDaspletosaurusTeratophoneusBistahieversorand Appalachiosaurusand the dromaeosaurids DromaeosaurusSaurornitholestesAtrociraptorand Bambiraptor.

Ceratopsians, such as PachyrhinosaurusStyracosaurusCentrosaurusMonocloniusBrachyceratops and Pentaceratops also existed. Among hadrosaurs, HypacrosaurusGryposaurusKritosaurusParasaurolophusCorythosaurusLambeosaurus and Prosaurolophus existed. During the latest Cretaceous, the Maastrichtian age, the diversity of dinosaurs saw a decline from the preceding Campanian stage.

North American herbivorous dinosaurs from this time period include the titanosaur sauropod Alamosaurusthe ceratopsians BravoceratopsRegaliceratopsTriceratopsLeptoceratopsTorosaurusNedoceratopsTatankaceratops the latter two possible species of Triceratopsand Ojoceratopsthe pachycephalosaurs PachycephalosaurusStygimolochDracorexand Sphaerotholusthe hadrosaurs AugustynolophusSaurolophus and Edmontosaurusthe ornithopod Thescelosaurus the ankylosaur Ankylosaurus and the nodosaurs DenversaurusGlyptodontopelta and Edmontonia.

Predatory dinosaurs from this time period included the tyrannosaurids TyrannosaurusNanotyrannus which may just be a juvenile of the former and Dryptosaurusthe ornithomimids OrnithomimusDromiceiomimusStruthiomimusthe oviraptorids AnzuLeptorhynchos and Ojoraptorsaurusthe troodontids PectinodonParonychodon and Troodonthe coelurosaur Richardoestesia and the dromaeosaurs Acheroraptor and Dakotaraptor.

The only recorded find of a dinosaur fossil in Central America consists of a single femur discovered from Middle Cretaceous age deposits in Comayagua Department in the central part of Honduras. The discovery was not formally described until where it was identified as the продолжение здесь of a small hadrosaur or iguanodontid, probably most beautiful place to live in nc former.

The fossil was an isolated metatarsus that had what states did dinosaurs live in collected by University of Pennsylvania explorer George Mason from woods near OlanchitoHonduras, though a vertebra was also mentioned to be found by locals. The bones have since been lost and their true identity remains indeterminable. This is a timeline of selected dinosaurs from the list above.
