The Middle Triassic is the second of three epochs of the Triassic period. It lasted from about 247.2 million years ago (mya) to ~237 mya.
Once the middle series in the Triassic was known as the Muschelkalk. This name is now only used for a unit of rock strata of Middle Triassic age, found in western Europe.
