Huge, 2.15" Fossil Phytosaur Vertebra - Arizona
This is a huge, 2.15" tall fossil vertebrae from a Triassic Phytosaur (Leptosuchus?) collected this fall from the Chinle Formation of Arizona. It's in pretty good condition with minimal erosion.
Phytosaurs looked similar to modern day crocodiles with one of the primary differences in appearance being that their nostrils were high in the head instead of at the front of the snout. This feature can be seen at the lower portion of this piece. Growing up to 16 feet long, they were one of the dominant predators of their time.
