6.3" Fossil Phytosaur Sacral Vertebra - Arizona
This is a 6.3" wide fossil sacral vertebra from a Triassic Phytosaur (Leptosuchus sp.?) collected from the Chinle Formation of Arizona. The remaining process is warped as a result of being subjected to millions of years of geologic forces. The vertebra was found in multiple pieces, requiring crack repair and gap fill restoration to piece it back together. It comes with the pictured, custom built display stand for presentation.
Phytosaurs are members of the order Phytosauria. These are 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.
