Emsian

From Wikipedia, the free encyclopedia

The Emsian is one of three faunal stages in the Early Devonian epoch. It lasted from 407 ± 2.8 million years ago to 397.5 ± 2.7 million years ago. It was preceded by the Pragian stage and followed by the Eifelian stage.


In North America the Emsian Stage is represented by Sawkill or Sawkillian time.
