World of Mesozoic Dinosaurs
Section Introduction
- The Mesozoic Era marks the period from 2.45 billion years to 65 million years ago, and ran for approximately 180 million years. The ancient reptiles that appeared in the late Paleozoic era rapidly developed and experienced explosive growth during the Jurassic Period(213 million∼144 million years ago), when large dinosaurs thrived on land, plesiosaurs in sea, and avian dinosaurs in the sky. At that time, ammonites, the invertebrate marine lifeforms, thrived, therefore this period is also called the Reptilian Age or the Dinosaur Age.
