Rhaetian

See Raetians for the Alpine people of antiquity. See Raetian language for their language.

The Rhaetian is, in geochronology, the latest age of the Triassic period or in chronostratigraphy the uppermost stage of the Triassic system. It lasted from ~208.5 to 201.3 ± 0.2 million years ago. It was preceded by the Norian and succeeded by the Hettangian (the lowermost stage or earliest age of the Jurassic).
