Phanerozoic the Mesozoic features the rise of reptiles on their 150 million year conquest of the Earth on the land, in the seas, and in the air. There are three periods in the Mesozoic: Triassic, Jurassic, and Cretaceous. The Triassic ranges from 250 million to 200 million years ago. The Triassic is a transitional time in Earth's history between the Permian Extinction and the lush Jurassic Period. It has three major epochs: Early Triassic, Middle Triassic and Late Triassic. The Early Triassic lasted between 250 million to 247 million years ago, and was dominated by deserts as Pangaea had not yet
Eldon George as a sparrow or robin. In 1986, a scientific team that included Paul Olsen, discovered hundreds of thousands of fossils at Wasson Bluff, one of the biggest troves ever found. Fossil discoveries on the Fundy shoreline are especially significant because they date from 200 million years ago, the boundary between the Triassic and Jurassic geological periods, when about half of the Earth's living creatures suddenly became extinct giving rise to dinosaurs and the mammals that eventually succeeded them. Many of the fossils that date from that time remain hidden, buried under North American forests, farmland or cities. But, the Fundy
