|---|---|---|
| P. Gol'din and M. E. Steeman 2015 | Modified from [12]. The scapula is anteroposteriorly elongated; the glenoid cavity displaced toward the anterior end. The deltopectoral crest of the humerus is long. Differ- ing from all Plicogulae, except Mesocetus longirostris, Pelocetus calvertensis and Parietobalaena campiniana, in: retaining plesiomorphic features of the lower jaw: the dorsal border in front of the mandibular condyle gradually ascending towards the coronoid process, wide mandibular foramen and wide mandibular canal. Differing from Mesocetus longirostris, “Aulocetus” latus, “Cetotherium” megalophysum and “Cetotherium” vandelli in: the wide skull with laterally expanded squamosals; straight ascending processes of maxillae which extend parallel to each other (rather than tapering and converging posteriorly); small lateral projection of the poste- rior meatal crest on the posterolateral side of the postglenoid process and paroccipital processes extending far posterior to the occipital condyles. Sharing only with Mesocetus longirostris: pos- terior ends of premaxillae fused with the maxillae and divided on the vertex by long, narrow and high (vertical plate-like) nasals; cervical vertebrae with wide transverse foramina, almost as wide as the centra (see also [12]).
