Cretaceous


 

The Cretaceous period is one of the major divisions of the geologic timescale, reaching from the end of the Jurassic period (about 146 MYA) to the beginning of the Paleocene epoch of the Tertiary period (65.5 mya). The end of the Cretaceous also defines the boundary between the Mesozoic and Cenozoic eras.
