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.
Primitive hadrosauromorph. Its only known fossil specimen found appeared to have been 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.
Herbivorous nodosaur from the state of Kansas. Like Claosaurus, the 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.
A small ornithopod endemic to Laramidia. Possible tracks have been discovered in Maryland and Virginia.
