摘要

目前，海象的活动范围仅限于北极圈附近的寒冷气候地区，它们是以前曾占据整个北半球沿海水域、种类繁多的海象类群的唯一幸存者。

Tusked walruses (Carnivora: Odobenidae) from the Miocene–Pliocene Purisima Formation of Santa Cruz, California (U.S.A.): a new species of the toothless walrus Valenictus and the oldest records of Odobeninae and Odobenini

Currently limited to cold climates near the Arctic circle, living walruses are the sole survivors of a previously much more diverse clade that occupied coastal waters throughout the northern hemisp...

期刊介绍： The Journal of Vertebrate Paleontology publishes original contributions on all aspects of vertebrate paleobiology, including vertebrate origins, evolution, functional morphology, taxonomy, biostratigraphy, phylogenetics, paleoecology, paleobiogeography, and paleoanthropology. JVP publishes high quality peer-reviewed original articles, occasional reviews, and interdisciplinary papers. It is international in scope, and emphasizes both specimen- and field-based based research and the use of high-quality illustrations. Priority is given to articles dealing with topics of broad interest to the entire vertebrate paleontology community and to high-impact specialist studies. Articles dealing with narrower topics, including notes on taxonomic name changes (unless these deal with errors published in JVP), preliminary site reports, and documentation of new specimens of well-known taxa, are afforded lower priority.
