Arctoceras is a genus of ceratitid ammonoids from the Lower Triassic with a moderately narrow discoidal shell and ceratitic suture.[1][2]
The shell of Arctoceras is generally involute with compressed whorls that are much higher than wide, flattened sides, narrowly rounded ventral rim, and sutures with wide low saddles and simple serrated lobes.[1]
