Globidens was a marine lizard that lived in the warm, shallow seas of the Late Cretaceous. It had strange, round teeth like little balls, perfect for crushing the hard shells of its prey. Unlike many other sea reptiles, Globidens was a shell-crushing specialist!1

Globidens was first described in 1912 by Charles W. Gilmore, based on an incomplete skull and a neck bone from Alabama, USA. The name means 'globe tooth' because of its round teeth.1
Oraindik eztabaidagai
Scientists are still debating exactly how many species of Globidens existed, as some fossils have been moved to other groups like Prognathodon.1
