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
Geology of the Seychelles 85 million years ago as the Mascarene ocean basin formed. The Deccan Traps hotspot, which poured out immense basalt flows in India 65 million years ago and ultimately formed islands such as Mauritius and Réunion, isolated Seychelles. The microcontinent was confined between northern Madagascar and western India until the Late Cretaceous and evolved during the Cenozoic through a process of rift and drift tectonics. The microcontinent was uplifted, eroded and impacted by volcanic eruptions. In the early Cenozoic, around 63 million years ago, alkaline plutonic and volcanic rocks emplaced to become the Silhouette and North islands. Seychelles sources most of
