These teeth are from an aquatic reptile that swam during the Age of Dinosaurs. Mosasaurs are one of the stars of the hit movie Jurassic World! A ferocious carnivore, these beasts could reach lengths of over 50 feet and fed on fish, turtles, ammonites, sharks and even other mosasaurs! Their closest relative is the Komodo Dragon. A super cool fossil- some of them even have other fossil remnants in the rock matrix!
