Anisian


Anisian

In the geologic timescale, the Anisian is the age of the Middle Triassic epoch and lasted from 245 million years ago until 237 million years ago, approximately. The Anisian age succeeds the Olenekian age of the Lower Triassic epoch and precedes the Ladinian age of the Middle Triassic epoch.

The earliest dinosaurs to date have been found in rock dating from the Anisian Age. [http://dml.cmnh.org/2003Dec/msg00070.html]
