Cretaceous Period, in geologic time, the last of the three periods of the Mesozoic Era. The Cretaceous began 145.0 million years ago and ended 66 million years ago; it followed the Jurassic Period and was succeeded by the Paleogene Period (the first of the two periods into which the Tertiary Period was divided).
What date was the late Cretaceous period?
The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous geological period is divided in the geologic time scale.
How did snakes survive the dinosaur extinction?
But snakes had a trick hidden up their scales: their unique burrowing habits, which helped them survive wildly fluctuating global temperatures. “Part of snakes’ survival comes down to the fact that most of them spend part of their lives in burrows,” Longrich says.

The Jurassic Period was the second segment of the Mesozoic Era . It occurred from 199.6 to 145.5 million years ago, following the Triassic Period and preceding the Cretaceous Period .
What are some Cretaceous organisms?
Lobsters. Lobsters (Decapoda) fossils,for example Hoploparia browni,are relatively rare in Cretaceous deposits.
