Goniatites are extict ammonoids, shelled cephalopods related to squid, octopus, and belemnites, that form the order Goniatitida. The Gonatitida originated from within the more primitive ammonoids in the Middle Devonian Period some 390 million years ago. Surviving the extinction of Late Devonian Period, goniatitids flourished during the Carboniferous and Permian Periods, only to become extinct at the end of the Permian some 250 million years ago.
