Fossil, Discoclymenia sp. Goniatit #11295847
Description
This is a fossil of a goniatite, Discoclymenia sp, from the Devonian era of Marocco. Goniatites are extinct ammonoids, shelled cephalopods related to squid, octopus, and belemnites, that form the order Goniatitida. The Gonatitida originated from within the more primitive anarcestine ammonoides in the Middle Devonian some 390 million years ago. Surviving the Late Devonian extinction, goniatitids flourished during the Carboniferous and Permian only to become extinct at the end of the Permian some 251.4 million years ago.
