All the material was collected from the Late <a href="/wiki/Miocene" title="Miocene">Miocene</a> to Early <a href="/wiki/Pliocene" title="Pliocene">Pliocene</a> (<a href="/wiki/Messinian" title="Messinian">Messinian</a> to <a href="/wiki/Zanclean" title="Zanclean">Zanclean</a>) <a href="/wiki/Capistrano_Formation" title="Capistrano Formation">Capistrano Formation</a>, <a href="/wiki/Orange_County,_California" title="Orange County, California">Orange County, California</a> alongside the remains of several other early odobenids.

The nares are large with thick borders and roofed by the <a href="/wiki/Nasal_bones" class="mw-redirect" title="Nasal bones">nasal bones</a>. The <a href="/wiki/Palate" title="Palate">palate</a> is arched and a pair of <a href="/wiki/Infraorbital_foramen" title="Infraorbital foramen">infraorbital foramen</a> enlarged. The later suggest that much like the modern species, <i>Osodobenus</i> had a mustache-like collection of whiskeres covering the upper lip. Behind the canines, the teeth are single-rooted with inflated bulbous crowns showing little wear. The first two <a href="/wiki/Incisors" class="mw-redirect" title="Incisors">incisors</a> of <i>Osodobenus</i> are transversely compressed with minor wear of the apices. The third incisor is notably longer and slender and there is no <a href="/wiki/Cingulum_(tooth)" title="Cingulum (tooth)">cingulum</a> on the inner side of the jaws as in other odobenids. The prominent <a href="/wiki/Canine_(tooth)" class="mw-redirect" title="Canine (tooth)">canines</a> are robust, conical and recurved. Compared to the width of the skull, these canines are approximately 50% larger than those of other basal walrus genera. The <a href="/wiki/Pulp_(tooth)" title="Pulp (tooth)">pulp cavity</a> is open which indicates that the canines were continuously growing, something only known from tusked odobenids. This however only applies to the males, while the female has smaller canines more proportional to the skull width. This indicates that the presence of tusks in <i>Osodobenus</i> was <a href="/wiki/Sexually_dimorphic" class="mw-redirect" title="Sexually dimorphic">sexually dimorphic</a>. The teeth of <i>Osodobenus</i> show a somewhat transitional form between the less specialised odobenids with a tooth specialisation score of 0.4 and lower and the more derived and specialised members of the group (score >0.5). This indicates that odobenids rapidly specialised during the late <a href="/wiki/Tortonian" title="Tortonian">Tortonian</a> to early <a href="/wiki/Messinian" title="Messinian">Messinian</a> of the Miocene, which included the development of tusks in later taxa. This again corresponds to what is observed in <i>Osodobenus</i>, whose canines form an intermediate form between what has previously been considered tusked and tuskless. Biewer and colleagues argue that the continuous nature of tusk growth in an evolutionary context makes a rigid separation futile and that <i>Osodobenus</i> represents the first walrus with canines that could be considered tusks.<sup id="cite_ref-B20_1-2" class="reference"><a href="#cite_note-B20-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Phylogeny">Phylogeny</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Osodobenus&action=edit&section=3" title="Edit section: Phylogeny"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p><i>Osodobenus</i> was recovered as a sister taxon to the <a href="/wiki/Neodobenia" class="mw-redirect" title="Neodobenia">Neodobenia</a><sup id="cite_ref-T21_2-0" class="reference"><a href="#cite_note-T21-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> in both parsimony phylogenetic analysis and Bayesian analyses, which makes it the basalmost walrus with canines that can be considered tusks.

of these enlarged canine teeth. <i>Osodobenus</i> and other tusked odobenids share an enlarged <a href="/wiki/Infraorbital_foramen" title="Infraorbital foramen">infraorbital foramen</a>, which correspond with the amount of facial nerves that connect to musculature and <a href="/wiki/Vibrissae" class="mw-redirect" title="Vibrissae">Vibrissae</a> (whiskers), the later being used by extant seals and <a href="/wiki/Sirenians" class="mw-redirect" title="Sirenians">sirenians</a> in foraging. Another trait that suggests that <i>Osodobenus</i> may habe been a <a href="/wiki/Benthic_zone" title="Benthic zone">benthic</a> feeder is the anatomy of the palate, which indicates that this genus much like extant walrus was a specialised suction feeder. Biewer and his colleagues note that these traits alone are not enough to fully establish <i>Osodobenus</i> as a benthic feeder, but argue that its feeding behavior may have been similar regardless. As some more derived odobenids lack these adaptations, it is possible that this ecology was evolved independently from crown walrus.<sup id="cite_ref-B20_1-4" class="reference"><a
