Cretaceous Period. The Cretaceous period began at the end of the Jurassic period approximately 144 million years ago and extended longer than any period (79 ma) to approximately 65 million years ago. The word Cretaceous comes from the word for chalk and the geological remains do indeed contain heightened chalk deposits.
The Mid-Cretaceous period is one period in the geologic past that stands out as distinctly warmer than today, particularly at high latitudes. During the mid-Cretaceous Period, 120-90 million years ago, fossil remains of plants and animals believed to inhabit warm environments, were found at much higher latitudes.he Mid-Cretaceous period is one period in the geologic past that stands out as distinctly warmer than today, particularly at high latitudes.
