Cretaceous to Eocene Period- C. 70-33 Million Years Ago

Name of which the family belongs: Otodontidaee
Informal name of the fossil: Otodus obliquus

A multi fossil consisting of multiple Otodus teeth, a Mosasaur tooth and vertebrae in matrix.

Otodus was a giant ocean predators, with an estimated body length between 30 to 40 feet. Otodus teeth were long, tapered and triangular, which were ideal for puncturing fish, as the main tooth was flanked by two smaller structures called cusplets. The Odotus is an extinct species of mackerel shark and based on evolutionary transitional evidence of their teeth, is thought to be one of the oldest ancestors of the megalodon shark.

Mosasaurs were large marine carnivores, feeding on fish, birds & other marine animals. Some species reaching lengths of 50 feet. They were fast, streamline and sleek with large flipper like paddles for arms and legs and a tail fin. Its teeth have a re-curved crown, almost smooth and slightly triangular in cross-section and is set on a bulbous root. Unlike other lizards, the individual teeth were located in separate sockets and not attached to the side of the jaw.
