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] Flood geologists use a geological system that more heavily relies on catastrophism and reject the uniformitarian assumptions behind the dates derived by secular geologists, and thus reject these dates (see geologic system). Instead, they would consider most if not all Jurassic strata to be laid during Noah's Flood. Flood geologists also point out that catastrophism is increasingly being accepted in the field of geology.

Many sediments containing dinosaur fossils are assigned to the Jurassic, which evolutionists believe to be the the peak time of the dinosaurs.
