9419802 Archibald This taxonomic, phylogenetic and functional studies of fossil walruses (Odobenidae sensu Demere) will focus on exceptionally well preserved and systematically informative skeletal material from the Emlong Collection (USNM, Smithsonian Institution). Specific objectives of this study are: (1) to document obobenid diversity from the early Miocene through the Pliocene (17-3 million years ago), (2) to evaluate the systematic relationships of these Neogene odobenids that are especially critical to walrus phylogeny, and (3) to use this phylogenetic framework to investigate adaptation of feeding strategies and locomotor patterns among odobenids and related pinnipeds (seals and sea lions).

9419802 Archibald 这项对海象化石 (Odobenidae sensu Demere) 的分类学、系统发育和功能研究将重点关注来自 Emlong 收藏（USNM、史密森学会）的保存异常完好且信息系统丰富的骨骼材料。 这项研究的具体目标是：(1) 记录从中新世早期到上新世（17-300 万年前）的奥贝尼科生物多样性，(2) 评估这些新近纪奥贝尼科生物的系统关系，这对海象系统发育尤其重要， (3) 利用这一系统发育框架来研究奥多贝科动物和相关鳍足类动物（海豹和海狮）的摄食策略和运动模式的适应性。
