The Cretaceous was a period with a relatively warm climate and high eustatic sea level. The oceans and seas were populated with now extinct marine reptiles, ammonites and rudists; and the land by dinosaurs. At the same time, new groups of mammals and birds as well as flowering plants appeared. The Cretaceous ended with one of the largest mass extinctions in [[Earth]] history, the [[K-T Extinction]], when many species, including the dinosaurs, pterosaurs, and large marine reptiles, disappeared. | The Cretaceous was a period with a relatively warm climate and high eustatic sea level.
