Reptiles were the primary large animals during the Cretaceous period. On land, there were dinosaurs, in the air were pterosaurs, and the oceans were inhabited by plesiosaurs and mosasaurs.
The Cretaceous period followed the Jurassic period and lasted from about 145 million to 66 million years ago. In the Cretaceous period, flowering plants became more dominant, dinosaurs continued to diversify, and large marine reptiles like mosasaurs thrived. However, the end of the Cretaceous period marked by a mass extinction event where dinosaurs and many other species went extinct.
