Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. W. Boessenecker et al. 2024 | Odobenin walruses possessing a humerus with a broad deltopectoral crest lacking a sharp crest, a greatly thickened greater tuberosity, greatly enlarged medial entepicondyle, proximal and distal ends massively enlarged, dia- physis relatively short, and narrow bicipital groove. Putative synapomorphies preserved in all species with a skull included toothlessness, numerous palatal foramina, and a pentagonal nasal. |
