Jurassic

The Jurassic is a geologic period and stratigraphic system that lasted about 58.3 million years, spanning from the end of the Triassic Period 201.4 Ma to the beginning of the Cretaceous Period, 143.1 Ma. The Jurassic constitutes the second and middle period of the Mesozoic Era as well as the eighth period of the Phanerozoic Eon and is named after the Jura Mountains, where limestone strata from the period were first identified.
