Molluscan Transition Across the K/T Boundary and Early Paleocene Recovery, Seymour Island, Antarctica

该奖项支持对南极洲西摩岛古生物学的持续研究。该奖项将允许数据减少，以完成正在进行的白垩纪晚期早期第三纪软体动物动物群的分类研究，这些研究是在之前美国赞助的探险队和最近阿根廷-美国联合探险队收集的材料中收集的。已经完成了对双壳类动物群组成的系统综述。预计随着这项工作的完成，南极晚白垩世/早第三纪的详细数据库将为白垩纪末南纬高纬度地区动物更替的性质以及早第三纪海洋动物的恢复提供新的见解。这些数据将为整合南美和澳大利亚正在进行的生物地理研究提供坚实的基础。

This award supports continued study of the paleontology of Seymour Island, Antarctica. The award will allow data reduction to complete the ongoing taxonomic study of the Late Cretaceous early Tertiary molluscan fauna collected during previous U.S. sponsored expeditions and recently collected material during a joint Argentine-American expedition. The systematic review of the bivalves component of the fauna has been completed. It is anticipated that with the completion of this work, a detailed data base for the late Cretaceous/early Tertiary of Antarctica will provide new insight not only into the nature of the faunal turnover in the high southern latitudes at the end of the Cretaceous, but also in to the recovery of the marine faunas during the early Tertiary. These data will provide a solid foundation for integrating ongoing biogeographic studies in South America and Australia.
