This award, provided by the Antarctic Geology and Geophysics Program of the Office of Polar Programs, supports a project to investigate Triassic and Jurassic dinosaurs and other vertebrates from the central Transantarctic Mountains of Antarctica. A field program to search for Upper Triassic to Jurassic age fossil vertebrates in the Beardmore Glacier region will be carried out in the 2003-04 austral summer. Initially, field efforts will concentrate on the Hanson Formation that has produced the only Jurassic dinosaur fauna from Antarctica. Further excavation of the Hanson dinosaur locality on Mt. Kirkpatrick will occur, followed by an extensive search of other exposures of the Hanson, Falla and Upper Fremouw Formations in the Beardmore area. A field party of six persons will allow two smaller groups to work independently at different sites. This group will operate for 3-4 weeks out of a small helicopter camp located in the Beardmore area. In addition to collecting new specimens an interpretation of the depositional settings for each of the vertebrate sites will be made. The second and third years of this project will be dedicated to preparation and study of the vertebrates. Antarctic vertebrates provide a unique opportunity to study the evolutionary and biogeographic significance of high latitude Mesozoic faunas and this project should result in significant advances in knowledge in this field.

该奖项由极地项目办公室的南极地质和地球物理项目提供，支持一项研究南极洲中部横贯南极山脉的三叠纪和侏罗纪恐龙及其他脊椎动物的项目。一项在比尔德莫尔冰川地区寻找上三叠纪至侏罗纪脊椎动物化石的实地计划将于 2003-04 年夏季进行。最初，实地工作将集中在汉森组，那里是南极洲唯一的侏罗纪恐龙动物群。将对柯克帕特里克山的汉森恐龙产地进行进一步挖掘，随后将对比尔德莫尔地区的汉森、法拉和上弗雷莫地层的其他暴露区域进行广泛搜索。六人的现场小组将允许两个较小的小组在不同的地点独立工作。该小组将在位于比尔德莫尔地区的一个小型直升机营地执行 3-4 周的任务。除了收集新标本外，还将对每个脊椎动物遗址的沉积环境进行解释。该项目的第二年和第三年将致力于脊椎动物的准备和研究。南极脊椎动物为研究高纬度中生代动物群的进化和生物地理学意义提供了独特的机会，该项目应会导致该领域知识的重大进步。
