Frasnian

The Frasnian is one of two faunal stages in the Late Devonian period. It lasted from 382.7 ± 1.6 million years ago to 372.2 ± 1.6 million years ago. It was preceded by the Givetian stage and followed by the Famennian stage.

Major reef-building was under way during the Frasnian stage, particularly in western Canada and Australia. On land, the first forests were taking shape. In North America, the Antler and Taconic orogenies peaked, which were contemporary with the Bretonic phase of the Variscan orogeny in Europe.
