9315831 Woodburne This award supports a study of terrestrial vertebrates from lower Cenozoic sediments on Seymour Island in the Antarctic Peninsula. Seymour Island contains rich and well preserved faunal and floral assemblages in a thick stratigraphic section that encompasses the Cretaceous-Tertiary boundary. Previous work has yielded marsupial and placental mammal fossils. The lower Cenozoic Sobral Formation contains terrestrial sediments that are likely to yield substantially more fossil material and this material would represent the earliest Tertiary vertebrates known from Antarctica. The objectives of this proposal are to understand the role of high latitude locations in biological evolution and dispersal of vertebrates in the early Tertiary. This work is likely to lead to a better understanding of migration patterns and evolutionary relationships between Australian and South American vertebrates. ***

9315831 Woodburne该奖项支持对南极半岛西摩岛新生代沉积物中陆生脊椎动物的研究。 西摩岛包含丰富的和保存完好的动物群和植物群组合在一个厚厚的地层部分，包括古近纪-第三纪的边界。 先前的工作已经产生了有袋动物和胎盘哺乳动物化石。 下新生代索布拉尔组含有陆地沉积物，可能产生更多的化石材料，这些材料将代表南极洲已知的最早的第三纪脊椎动物。 这个建议的目的是了解高纬度地区的生物进化和脊椎动物的扩散在第三纪早期的作用。 这项工作可能会导致更好地了解澳大利亚和南美脊椎动物之间的迁移模式和进化关系。 ***
