Cretaceous Reptiles (1865) Plate XIII
This is Plate XIII from "Cretaceous Reptiles of the United States" (1865). Most of the fossils shown are teeth and jaw fragments of Hadrosaurus foulkii. The two larger items in the bottom right are two views of what Leidy suspected was a vertebra (backbone) fragment of a young Hadrosaurus. The four teeth shown on the bottom left belonged to Astrodon, which may have been a sauropod dinosaur.
