Mosasaurus Fossil Collection
Mosasaurs were air-breathing marine predators living in shallow inland seas in the late Cretaceous period. These large animals (up to 50') are not dinosaurs but reptiles related to snakes and monitor lizards. Mosasaurs give birth to live young in water, unlike turtles, which give birth to live young on land. Due to the delicate nature of their scales, mosasaurid fossil specimens rarely show scale imprints. Teeth are a different matter! They ate ammonites, fish, turtles, plesiosaurs, and even sea birds. Explore our selection, which is regularly updated with new items discovered during our travels.
