Facts about dinosaurs in Triassic Period
The Triassic period was the first period of the Mesozoic Era. It was a miserable time in the Earth’s history. It occurred immediately after the mass extinction. It was the end of Permian period. At the beginning of Triassic period, most of the continents were part of a giant supercontinent named as Pangaea. Climate of this supercontinent was very much dry. Everything was in extreme. Summers were very hold and winters were very cold. Later, the supercontinent Pangaea got divided in two different continents, Gondwana and Laurasia.
It was an era of changes. It was the rising time for huge reptiles, dinosaurs. At the beginning of Triassic period, there was a super continent Pangaea, which was situated on one side of the equator and extended towards the poles. Huge reptiles like ichthyosaurs with dolphin shaped body and plesiosaurs with long neck, preyed on fishes and squids. Microscopic plant named as phytoplankton was at the very bottom of the food chain.
The evolution of dinosaurs happened in the late Triassic period. It happened around 230 million years ago. Dinosaurs were the first mammals on the earth. The two footed carnivore Coelophysis was the first dinosaur that reached up to 9 feet approximately in height and weighed around 45 kg. After sometime, around 28 feet long Plateosaurs showed up. That is how the Triassic period ended and Jurassic Period started. Dinosaurs dominated this next period.
