---|---|---|
Y. Tanaka and N. Kohno 2015 | Archaeodobenus akamatsui is an archaic odobenid with a slender and small cranium and non-tusked, moderate-sized upper canine. Distinguished from other archaic odobenids (Prototaria primigena, P. planicephala, Proneotherium repenningi, Neotherium mirum, Kamtschatarctos sinelnikovae and Pseudotaria muramotoi) by the following derived characters: pentagonal basioccipital (character 30), blade-like spinous process of axis (character 91). Distinguished from later diverging odobenids (Imagotaria downsi, Pontolis magnus, dusignathines and odobenines) by retention of the following primitive characters: deep mandibular fossa (character 26); small mastoid process (character 33); two distinct roots on premolars (expect P1) (character 74 and 76). |
