The Triassic Period, in geological time, is the first period of the Mesozoic Era and began 252 million years, with no end to the Permian Period. This period ended in 201 million years, being realized by the Jurassic period.
It is in the Triassic period that the first dinosaurs appear alongside flying reptiles called pterosaurs. During this period, terrestrial life undergoes intense diversification in both fauna and flora and the phenomenon of the division of the super continent Pangaea begins. The repopulation of the planet occurs after the extinction that marked the end of the Permian Period.
This period is also marked by the absence of polar ice caps, hot and arid climate and low animal diversity in both terrestrial and marine environments.
The name of the Triassic Period was given by the German geologist Friedrich August von Alberti in 1834. The scientist concluded that three rock types characterized the Triassic: red river sandstone, fossiliferous marine limestone and continental sandstone.
