What is List of North American dinosaurs?
This is a '''list of [[dinosaur]]s''' whose remains have been recovered from '''[[North America]]'''. North America has a rich dinosaur fossil record with great diversity of dinosaurs. This may not mean the dinosaurs were more diverse or abundant; it may be because substantial resources have been devoted to the North American fossil record. The [[Middle Jurassic]] is the only poorly represented time period in North America, although several Middle Jurassic [[wikt:locality|localities]] are known from Mexico. Footprints, eggshells, teeth, and fragments of bone representing theropods, sauropods, and ornithopods have been found, but none of them are diagnostic to the [[genus]] level. The [[Upper Jurassic|Late Jurassic]] of North America, however, is the exact opposite of the Middle Jurassic. The Late Jurassic [[Morrison Formation]] is found in several U.S. states, including [[Colorado]], [[Utah]], [[Wyoming]], [[Montana]], [[New Mexico]], [[Oklahoma]], [[South Dakota]], and [[Texas]]. It is notable as being the most fertile single source of dinosaur fossils in the world. During the [[Lower Cretaceous|Early Cretaceous]] period, new, various types of dinosaurs appeared. Sauropods like ''[[Cedarosaurus]]'' were still present, but they were not as diverse as they were in the Jurassic. Theropods from the early Cretaceous of North America include ''[[Deinonychus]],'' ''[[Utahraptor]]'', ''[[Acrocanthosaurus]]'', and a new genus of theropod, ''[[Microvenator]]''. Huge plant-eating, long-necked dinosaurs included ''[[Astrodon]]'' and the [[Upper Cretaceous|Late Cretaceous]] sauropod ''[[Sauroposeidon]]''. Ornithischians were more diverse than they were in the Jurassic Period. ''[[Tenontosaurus]]'', ''[[Hypsilophodon]]'', ''[[Iguanodon]]'', ''[[Protohadros]]'', and ''[[Eolambia]]'' are some of the ornithopods that lived then during the Early Cretaceous. Ankylosaurs replaced their stegosaur cousins in the Cretaceous. Ankylosaurs from the Early Cretaceous timeline of North America include ''[[Sauropelta]]'' and the popu
