List of Appalachian dinosaurs
This is a list of dinosaurs whose remains have been recovered from Appalachia. During the Late Cretaceous period, the Western Interior Seaway divided the continent of North America into two landmasses; one in the west named Laramidia and Appalachia in the east. Since they were separated from each other, the dinosaur faunas on each of them were very different. For example, nodosaurs were common in Appalachia, but they were rare in Laramidia, and there were only specialized forms, such as Edmontonia and Panoplosaurus. This is an example of how isolated faunas develop differently.
List of Appalachian dinosaurs
| Name | Period | Diet | Notes |
| Acrocanthosaurus | Cretaceous | carnivore | - Large carnivorous carcharodontosaurid found in Maryland. |
| Ammosaurus | Jurassic | herbivore | - Small herbivorous sauropodomorph found in Connecticut. |
| Anchisaurus | Jurassic | herbivore | - Small herbivorous sauropodomorph found in Connecticut. |
| Appalachiosaurus | Cretaceous | carnivore | - Large tyrannosauroid from Alabama. |
| Arkansaurus | Cretaceous | carnivore | -An indeterminate theropod from Arkansas. Many paleontologists believe it could be related to Ornithomimus. |
| Astrodon | Cretaceous | herbivore | - Large herbivorous sauropod found in Maryland. |
| Claosaurus | Cretaceous | herbivore | - A primitive hadrosaur. The only known fossil specimen found got washed into the Western Interior Seaway. It is believed to be from Appalachia because it was found closer to the Appalachia side of the sea and is unknown from Laramidia. |
| Coelosaurus | Cretaceous | carnivore/omnivore | - May be synonymous with Ornithomimus. |
| Deinonychus | Cretaceous | carnivore | - A medium-sized raptor found in Maryland. |
| Diplotomodon | Cretaceous | carnivore | - A dubious name for a species of tyrannosauroid from New Jersey, possibly for Dryptosaurus or a potentially new genus. |
| Dryptosaurus | Cretaceous | carnivore | - Medium-sized tyrannosauriod from New Jeresy. |
| Eotrachodon | Cretaceous | herbivore | - A hadrosaur from Alabama known from a nearly complete skeleton. |
| Hadrosaurus | Cretaceous | herbivore | - First known dinosaur skeleton from the United States. Discovered in 1858 in Haddonfield, New Jersey. |
| Hypsibema | Cretaceous | herbivore | - Little known hadrosaur first discovered in North Carolina in 1869. Better material of a second species was found in Missouri. |
| Lophorhothon | Cretaceous | herbivore | - A hadrosaur from Alabama with skull fragments discovered. |
| Niobrarasaurus | Cretaceous | herbivore | - Another example of a nodosaurid dinosaur from Kansas. |
| Parrosaurus | Cretaceous | herbivore | - A junior synonym of Hypsibema missouriensis. It is the state dinosaur of Missouri. |
| Priconodon | Cretaceous | herbivore | - A nodosaur from Maryland found only from fossilized teeth. |
| Propanoplosaurus | Cretaceous | herbivore | - A nodosaurid dinosaur from Maryland. |
| Podokesaurus | Jurassic | carnivore | - Small therapod from Connecticut River Valley, may be synonymous with Coelophysis. |
| Silvisaurus | Cretaceous | herbivore | - A herbivorous nodosaur from the state of Kansas. Similarly to Claosaurus, This specimen found was probably washed into the Western Interior Seaway. It is believed to be from Appalachia because it was found closer to the Appalachia side of the sea. |
| Tenontosaurus | Cretaceous | herbivore | - A herbivorous iguanodontid whose fossil remains have been discovered in Maryland. |
| Zephyrosaurus | Cretaceous | herbivore | - A herbivorous hypsilophodontid whose fossil remains have been discovered in Maryland and Virginia. |
