Cretaceous. The Cretaceous ended with a large mass extinction, the Cretaceous - Paleogene extinction event, in which many groups, including non-avian dinosaurs, pterosaurs and large marine reptiles died out. The end of the Cretaceous is defined by the abrupt Cretaceous - Paleogene boundary (K - Pg boundary), a geologic signature associated with the mass extinction which lies between the Mesozoic and Cenozoic eras. The Cretaceous - Paleogene (K - Pg) extinction event, also known as the Cretaceous - Tertiary (K - T) extinction, was a mass extinction of some three-quarters of the plant and animal species on Earth that occurred over a geologically short period of time approximately 65 million years ago. Dinosaur. Their dominance continued through the Jurassic and Cretaceous periods and ended when the Cretaceous - Paleogene extinction event led to the extinction of most dinosaur groups 66 million years ago. Paleogene. The Paleogene is most notable for being the time during which mammals diversified from relatively small, simple forms into a large group of diverse animals in the wake of the Cretaceous - Paleogene extinction event that ended the preceding Cretaceous Period.
The Cretaceous is unrelated with Paleogene extinction event.
