Mosasaurs are large, carnivorous marine reptiles that went extinct at the same time as the dinosaurs. Michael Caldwell is a paleontologist and mosasaur expert from the University of Alberta in Canada. He has visited sites around the world examining mosasaur fossils, and has found that New Zealand mosasaurs were much more wide-ranging than previously thought.
