Collaborative Research: The Geology and Paleontology of one Sobral Formation, Seymour Island, Antarctic Peninsula

9315831伍德伯恩该奖项支持对南极半岛西摩岛下新生代沉积物中陆生脊椎动物的研究。西摩岛在围绕白垩纪-第三系界线的厚厚的地层剖面中包含丰富且保存良好的动植物组合。之前的工作已经产生了有袋类和胎盘类哺乳动物化石。下新生代Sobral组含有陆地沉积物，很可能产生更多的化石物质，这些物质将代表南极洲已知的最早的第三纪脊椎动物。这一建议的目的是了解高纬度位置在早第三纪脊椎动物生物进化和扩散中的作用。这项工作可能有助于更好地理解澳大利亚和南美脊椎动物之间的迁徙模式和进化关系。***

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. ***
