Woodbury Formation Late Cretaceous , Campanian. Possibly a synonym of Stegoceras . United States Colorado Montana? May have been a basal diplodocoid .
United States Montana Wyoming. Two morphotypes of plates are known, which could be explained by sexual dimorphism . 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 . United States Missouri North Carolina. Usually seen as synonymous with Stegosaurus but may be a separate genus due to differences in its vertebrae . 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 . 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 . Dockum Group Late Triassic , Norian. Analysis of its teeth show it could chew like a mammal, an adaptation to eating tough, fibrous plants . Has been suggested to be semi-aquatic due to its tall, narrow tail . Remains of hundreds of individuals, including juveniles, eggs, and nests, have been found at a single site .
United States Colorado? Potentially a close relative of South America megalosauroids . 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 . Described as a macronarian  but has since been reinterpreted as a turiasaur closely related to Mierasaurus . Horseshoe Canyon Formation , St. Often restored with a short nasal horn although this may be a displaced cheek horn .
Had a nasal arch that was not as tall as that of Gryposaurus. Described as a dwarf tyrannosaurid although undescribed remains suggest a size comparable to Albertosaurus .
Possessed an enlarged nasal cavity and two long, curving horns similar to those of modern cattle. Had a distinctive notch at the very top of its frill, similar to its potential ancestor Pentaceratops . Known from three partial skeletons. The specific name, N. Originally mistakenly believed to have been aquatic .
Closely related to Asian ankylosaurs . United States New Mexico Utah. Would have lived in the marshes and swamps  along the Turonian shoreline . Only known from an incomplete pair of pubes. Potentially a synonym of Scolosaurus . May have possessed a sickle claw similar to those of dromaeosaurids . One referred specimen preserves impressions of ostrich-like feathers covering most of its body .
Eggs considered to belong to this taxon may have actually come from a troodontid . United States Idaho Montana. Lakota Formation Early Cretaceous , Valanginian. Originally named as a species of Camptosaurus. United States Montana South Dakota. Canada Alberta United States Alaska. Although several restorations depict it with the spikes of Edmontonia and the tail club of Ankylosaurus , this is most likely incorrect. Had long toes which may be an adaptation to walking on soft soils in watercourses and marshlands .
Had enlarged nasal cavities that gave it an acute sense of smell, even more powerful than that of contemporary theropods . Originally assigned to Euoplocephalus but given its own genus because of several morphological differences. United States Massachusetts. May have had a tail one and a half times longer than the rest of its skeleton . May be identical to Latenivenatrix . Denver Formation Late Cretaceous , Maastrichtian. Patuxent Formation Early Cretaceous , Aptian.
Woodbine Formation Late Cretaceous , Cenomanian. Potentially synonymous with Corythosaurus , although this cannot be confirmed due to a lack of cranial remains . Originally described as a specimen of Struthiomimus. Canada Alberta United States Texas. Teeth assigned to this genus have been recovered all around the world, although they may not represent a single taxon. Had a short, solid crest that pointed directly upwards.
A larger, more well-known species has been found in Mongolia. United States Oklahoma Texas. Could raise its head up to 18 metres 59 ft in the air, the height of a six-storey building . Its second premaxillary teeth could be adapted to preening feathers .
Preserves evidence of a wishbone similar to that of modern birds. Navajo Sandstone Early Jurassic , Pliensbachian. The holotype may have died when a sand dune collapsed on it . May be part of a unique clade of ceratopsians only known from southern Laramidia . Has been described as “boldly audacious”. Possibly identical to Ceratops . Dinosaur Park Formation? Late Cretaceous , Campanian. May have been an indiscriminate bulk-feeder due to the shape of its snout .
Canada Utah. Canada Alberta United States Montana? Possessed several long horns jutting out from the top of its frill, the patterns of which could have varied between individuals . Small yet already possessed several features of large, derived tyrannosaurids, including an arctometatarsus. Shares features with both diplodocids and dicraeosaurids, but is more likely a member of the latter group  .
The holotype specimen preserves a pathology on its sickle claw . Remains of this genus are often found associated with skeletons of Deinonychus . Had a teardrop-shaped hole on the top of its frill which was almost closed off by a pair of epoccipitals. However, no matter where you live, you can bet there was at least some prehistoric life there five million, 50 million, or million years ago.
Use the list below to see which dinosaurs and prehistoric animals lived in your state during the Paleozoic, Mesozoic, and Cenozoic Eras. It shouldn’t be surprising that Alaska, California , and Colorado are the big winners when it comes to the most fossil finds among these states.
Alaska has long been poised for migration routes, with California and Colorado on the route to South America. Every state here does have some interesting finds, though. For instance, the coastal states like Florida, Georgia , and Delaware have a nice selection of marine fossils. Even Connecticut has a good collection of footprints. Within these states, you’ll find some of the best-known dinosaurs.
The Stegosaurus and Tyrannosaurus rex, for instance, have been found in both California and Colorado. Mammoths ranged from Alaska to California, and over to Arkansas and Florida , while sabertooth cats have been found in both California and Florida.
Alabama was home to a large tyrannosaur called Appalachiosaurus, as well as the prehistoric shark Squalicorax. The most famous dinosaur to be discovered in Arizona is the Dilophosaurus. The mega finds of other states are not found in any from this group, though they do offer some very interesting prehistoric revelations. The state with the most actual dinosaur discoveries here is a surprise: Maryland.
As for the other states, Hawaii has only a few prehistoric animals because it was underwater for much of history. Likewise, the Midwestern states were submerged as well, so many of the fossils found in Kansas , Idaho , and Iowa were aquatic.
While mammoths have been found in Illinois , Indiana , and Iowa, and mastodons in Kentucky and Louisiana , these were simply not fossil-rich states. But reversals happen rather frequently–every million years Fossil photos can also be viewed as published plates within many online USGS publications. The USGS fossil Dinosaur communities were separated by both time and geography. Different dinosaur species lived during each of these three periods.
For example, the Jurassic dinosaur Stegosaurus had already been extinct for approximately 80 million years before the After the dinosaurs died out, nearly 65 million years passed before people appeared on Earth. However, small mammals including shrew-sized primates were alive at the time of the dinosaurs. Some scientists who study dinosaurs vertebrate paleontologists now think that birds are direct descendants of one line of carnivorous dinosaurs, and some consider that they in fact represent modern Scientists have conflicting opinions on this subject.
Some paleontologists think that all dinosaurs were ‘warm-blooded’ in the same sense that modern birds and mammals are: that is, they had rapid metabolic rates. Other scientists think it unlikely that any dinosaur could have had a rapid metabolic rate. Some scientists think that very big dinosaurs could have had warm bodies because of their Dinosaurs went extinct about 65 million years ago at the end of the Cretaceous Period , after living on Earth for about million years.
If all of Earth time from the very beginning of the dinosaurs to today were compressed into days one calendar year , the dinosaurs appeared January 1 and became extinct the third week of September. Using this same time scale, the Earth would have formed Paleontologists don’t know for certain, but perhaps a large body size protected them from most predators, helped to regulate internal body temperature, or let them reach new sources of food some probably browsed treetops, as giraffes do today.
No modern animals except whales are even close in size to the largest dinosaurs; therefore, paleontologists think that the dinosaurs’ world was much Where to Rock Hunt Gems in Idaho.
