1.1 (as noun the Cretaceous) The Cretaceous period or the system of rocks deposited during it.

The Cretaceous lasted from about 146 million to 65 million years ago. The climate was warm, and the sea level rose; the period is characterized especially in northwestern Europe and parts of North America by the deposition of chalk. The first flowering plants emerged, and the domination of the dinosaurs continued although they died out quite abruptly toward the end of it


Late 17th century: from Latin cretaceus (from creta 'chalk') + -ous.
