The Tertiary Period began about 66 million years ago with a mass extinction that ‘clocked’ the dinosaurs and ended when the ice ages of the Quaternary Period began, about 2.6 million years ago.The Cretaceous Period began 145 million years ago (Mya) and ended 66 Mya. It lasted for 79 million years. It was the longest period of the Mesozoic Era. It was the third and final period of the Mesozoic Era. The Cretaceous Period was preceded by the Jurassic Period, and followed by the Paleogene Period.
