Goniatite

Goniatites are extinct ammonoids related to squid, octopus and belemnites that form the order Goniatitida. Goniatites are cephalopods which derived from the Agoniatitida 390 million years ago during the Middle Devonian Era. Goniatites survived during the Late Devonian extinction only to become extinct at the end of the Permian Era (139 million years later.)
