The Goniatitida constitute an order of ammonoid cephalopods from the late Paleozoic and are found in Middle Devonian to Upper Permian marine sedimnets. The Goniatitida diversified into two main lineages in the Early Carboniferous (Mississippian) and subsequently into a number of sublineages, forming different families and superfamilies.

Goniatitids (goniatites) are united by a basic suture of 8 simple lobes, less in primitive forms, more that may be ammonitic in advanced forms, and a [[siphuncle]] that is prosiphonate. (M F&S)
