Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| G. Bianucci et al. 2013 | Globicetus hiberus n. gen., n. sp. differs from all other ziphiids in the large spherical medial rostral prominence formed by the fused premaxillae, in the large prominence of the right premaxilla anterior to the right premaxillary sac fossa, and in the barely marked antorbital notch, related to the important widening of the rostrum base. Among the other ziphiine genera it further differs from Ziphius and Izikoziphius in the medial fusion of the premaxillae closing the mesorostral groove; it shares with Imocetus n. gen. and Tusciziphius the anterior part of the nasal contacting the premaxillary crest and the extreme ossification and fusion of the vertex elements, but it differs from Imocetus n. gen. in lacking a wide facial depression, rostral maxillary spur-shaped crest, and in having the premaxillary foramina not located posterior to the level of the antorbital notch; it differs from Tusciziphius in the less transversally expanded vertex (lower width between the premaxillary crests, and lower distance between maxillae posterior to the vertex), and in the posterolateral direction of the right premaxillary crest. It further differs from the possible ziphiine Caviziphius in shallower excavation of the premaxillary sac fossae. |
