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]
