Two Phytosaur Teeth In Sandstone - New Mexico
This is two Phytosaur (Redondasaurus) teeth still embedded in the sandstone in which they were found. These teeth are still embedded in the rock.
Phytosaurs are members of the order Phytosauria. These were semiaquatic, crocodile-like reptiles characterized by long snouts, conical teeth, short legs and long, low slung bodies. They had skin armored with scale like scutes. It is not clearly understood when Phytosaurus evolved. A number of apparently antecedent species have been found in the fossil record but their relationship to Phytosaurs is still being debated. Phytosaurus disappears from the fossil record during the Triassic- Jurassic Extinction, about 200 million years ago.
