The Cretaceous was a period in Earth's history. This period is notable because it marked the end of the dinosaurs. The Cretaceous period derives its name from the Latin word for chalk, creta, a mineral that has been found in extensive beds at this time. Reptiles were by far the dominant group, with dinosaurs ruling the land, while other creatures inhabited the skies and the seas.
