.58" Triassic Phytosaur (Redondasaurus) Tooth - Arizona

This is a finely serrated, posterior tooth for a Redondasaurus gregorii, one of the largest Phytosaurs. It comes from the Petrified Forest Member of the Chinle Formation in Arizona. Redondasaurus is considered by many to be synonymous with Pseudopalatus.

Fine serrations can be seen on both edges of the tooth. There is some feeding damage to the tip and enamel wear. Comes with an acrylic bubble case.



Phytosaurs looked similar to modern day crocodiles with some minor differences. The main one being that their nostrils were up high on the head instead of at the very front of the snout. They grew up to 16 feet in length and were certainly one of the dominant predators during the Triassic.
