Mosasaurs breathed air, were powerful swimmers, and were well-adapted to living in the warm, shallow seas that were common during the Late Cretaceous Period. They had a large shark-like tail and a double hinged jaw, like modern day snakes, so they could swallow their prey whole. This large, reddish brown tooth will evoke a lot of discussion about dinosaurs and their choices for dinner.
Teeth measure approximately 1.25" - 2.00"
