Ammonites are externally shelled cephalopods and range in geologic age from the Devonian to the Late Cretaceous. They comprise nine orders that may be informally grouped into the paleo-, meso-, and neoammonoidea. The paleoammonoidea consists of the Devonian-Permian goniatites, anarcestids, clymeniids, and prolecanitids.
