Globidens is an extinct genus of lizard belonging to the marine mosasaur family.

The 6 m (20 ft) long creature looked like a regular mosasaur, possessing a streamlined body with flippers, a laterally flattened tail and powerful jaws. However, its teeth were vastly different from other mosasaurs. Generally, these creatures had sharp teeth evolved to grab soft, slippery prey like fish and squid. Globidens, on the other hand, had blunt, round teeth which were much better suited for crushing tough armored prey like ammonites. While other mosasaurs also had blunt teeth in the back of the jaws which could crush ammonites, none were as specialized in armored prey as Globidens.
