Phenacoceratidae is one of three families of the superfamily Dimeroceratoidea.[1] The family is placed in the order Goniatitida,[2] and was first named by Rudolf Wedekind in 1918 who treated the group as a subfamily.[3] The family was named for Phenacoceras, a junior synonym of Clymenoceras.[3] They are an extinct group of ammonoids,[1] which are shelled cephalopods related to squids, belemnites, octopodes, and cuttlefish, and more distantly to the nautiloids.[4] They were fast-moving free-swimming (nektonic) carnivores.[1]
