The Jurassic Period is a geological period that lasted from about 200 million to 145 million years ago. The Jurassic Period is characterized by the appearance of the first dinosaurs. During the early part of the Jurassic, there was a major Triassic-Jurassic extinction event, which wiped out many species and paved the way for the Age of Dinosaurs.
The Jurassic was a time of great change on Earth. The climate was warmer than it is today, and there were no polar ice caps. The landscape was lush and green, with dense forests covering much of the land. The seas were teeming with life, including giant reptiles such as ichthyosaurs and plesiosaurs.
The first dinosaurs appeared during the late Triassic period, but it wasn’t until the early Jurassic that they began to dominate the landscape. Among the most famous dinosaurs of this time are Allosaurus, Apatosaurus, Diplodocus, Stegosaurus, and Triceratops. These massive creatures ruled the earth for over 100 million years before finally going extinct at the end of the Cretaceous period.
