Gorgeous, 2.09" Serrated Fossil Phytosaur Tooth - Arizona
This is a gorgeous 2.09" long tooth of a Triassic Phytosaur collected from the Chinle Formation of Arizona. Both edges still have serrations and the enamel is in excellent condition. There is a repaired crack near the tip with some gap fill restoration along one edge.
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.
