Straight from wikipedia.....
The Cretaceous Period is one of the major divisions of the geologic timescale, reaching from the end of the Jurassic Period (i.e. from about 146 to 136 million years ago (Ma)) to the beginning of the Paleocene epoch of the Tertiary Period (about 65.5 to 64 Ma). As the longest geological Period, the Cretaceous constitutes nearly half of the Mesozoic. The end of the Cretaceous defines the boundary between the Mesozoic and Cenozoic eras.
I am guessing that was a LONG time ago?
