Odobenus (walrus) (see text for more) |
Odobenidae is a family of pinnipeds, of which the only extant species is the walrus (Odobenus rosmarus). In the past, however, the group was much more diverse, and includes more than a dozen fossil genera.
Taxonomy
All genera, except Odobenus, are extinct.[1]
- †Archaeodobenus
- †Prototaria
- †Proneotherium
- †Nanodobenus
- †Neotherium
- †Imagotaria
- †Kamtschatarctos
- †Pelagiarctos
- †Pontolis
- †Pseudotaria
- †Titanotaria
- Clade Neodobenia[2]
- †Gomphotaria
- Subfamily Dusignathinae
- Subfamily Odobeninae
In re-analyzing Pelagiarctos, Boessenecker et al. (2013) proposed the phylogenetic relationships of Odobenidae as follows (this analysis excluded Archaeodobenus, Titanotaria, Nanodobenus, and Pliopedia; and included Enaliarctos, Pteronarctos, Allodesmus, Desmatophoca, Callorhinus, Monachus, and Erignathus):[3]
| | Enaliarctos emlongi † | | | | Pteronarctos goedertae † | | | Desmatophocidae | | | Otariidae | Callorhinus ursinus | | Phocidae | | | Imagotariinae | | Prototaria primigenia † | | | | Proneotherium regenningi † | | | | Neotherium mirum † | | | Kamtschatarctos sinelnikovae † | | | | Pseudotaria muramotoi † | | | | | Pelagiarctos sp. † | | | Imagotaria downsi † | | | | | | Pontolis magnus † | | | Dusignathinae | | Dusignathus santacruzensis † | | | Gomphotaria pugnax † | | | Dusignathus seftoni † | | | | Odobeninae | | | | | | | | | | | | | | | | | | | | | |
