Jurassic Period

Detailed Overview

The Jurassic period was the golden age of dinosaurs, featuring the largest land animals ever to exist, including giant sauropods like Diplodocus and Brachiosaurus. This period saw the first appearance of birds, evolving from small theropod dinosaurs. The world was generally warm and humid, with no polar ice caps, and featured extensive shallow seas teeming with marine reptiles like ichthyosaurs and plesiosaurs. Primitive mammals remained small and mostly nocturnal.
