The Jurassic period is part of the geologic system of classifying geologic formations.

The Jurassic period is part of the Mesozoic era, and is divided into Lower, Middle, and Upper epochs. The Jurassic is preceded by Permian era and followed by the Cretaceous era.

The Jurassic was named from the French word (Jurassique) for the Jura mountains of Switzerland.[1][2]

Under the uniformitarian dates assigned by secular geologists, it represents approximately the period of Earth's history from 200 million years ago to 145 million years ago.[3] Young Earth creationists reject these dates (see geologic system).
