Triassic Period



The Triassic period was the first of three periods in the Mesozoic Era (the others being the Jurassic period and the Cretaceous period), and occured between 248 million and 213 million years ago.

It was during the Triassic period that archosaurs ("ruling reptiles"), including dinosaurs, crocodiles, and Pterosaurs first evolved. Prior to the Triassic, during the previous Permian era, mammal-like reptiles had been the dominant land animals. Some survived into the Triassic, but they dramatically declined, apparently out-competed by the dinosaurs. The mammal-like reptiles did however give rise to the first mammals, these being tiny mouse-sized animals. The dominant plants during the Triassic period were conifers, ferns, ginkgos and horsetails.

The late Triassic period

The World in the Triassic
Here is a map of the world during the early Triassic (about 225 million years ago). At this time, all the continents were combined into one massive super-continent, known as Pangaea:

The different geography of the world also led to a different climate. On the whole, the Triassic was generally hot and dry, and there was no glaciation or ice caps at the poles (polar regions were moist and temperate). The interior of Pangaea would have had a highly seasonal continental climate, with very hot summers and cold winters.
