The Cretaceous ([pronkrᵻˈteɪʃəs],) is a geologic period and system that spans 79 million years from the end of the Jurassic Period million years ago (Mya) to the beginning of the Paleogene Period Mya. It is the last period of the Mesozoic Era. The Cretaceous Period is usually abbreviated K, for its German translation Kreide (chalk). 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 is yet to start.
