This award, provided by the Antarctic Geology and Geophysics Program of the Office of Polar Programs, supports vertebrate paleontological research in the Transantarctic Mountains. Antarctic field work, to search for and collect new terrestrial vertebrates of Triassic and Jurassic age, will be conducted in the austral summer of 1999-2000. During this season, exposures of the Feather and Lashly Formations in southern Victoria Land will be explored with the support of helicopters operating from McMurdo Station. Field efforts will concentrate on finding exposures equivalent to the Hanson Formation that has produced the only Jurassic dinosaur fauna from Antarctica and searching for new middle to upper Triassic fossil vertebrates. In addition to collecting new fossil specimens, an interpretation of the taphonomic/depositional settings for each of the localities will be made. The preparation and study of the vertebrates will occur during the second year of this project and will include investigation of the evolutionary significance of the member taxa of these high latitude Mesozoic faunas. Antarctic vertebrates of several different ages spanning the Triassic to Jurassic that have been discovered in recent years provide a unique opportunity to study the evolution of high latitude faunas. These faunas also contribute to our understanding of high latitude climates during the Mesozoic.

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，支持横贯南极山脉的脊椎动物古生物学研究。南极实地工作将在1999年至2000年的南方夏季进行，旨在寻找和收集三叠纪和侏罗纪时期的新陆生脊椎动物。在这个季节，我们将在麦克默多站运营的直升机的支持下探索维多利亚州南部的 Feather 和 Lashly 地层。实地工作将集中于寻找与汉森组相当的暴露区域，该组是南极洲唯一的侏罗纪恐龙动物群，并寻找新的中上三叠世脊椎动物化石。除了收集新的化石标本外，还将对每个地点的埋藏/沉积环境进行解释。脊椎动物的准备和研究将在该项目的第二年进行，其中包括对这些高纬度中生代动物群成员类群的进化意义的调查。近年来发现的跨越三叠纪至侏罗纪的几种不同时代的南极脊椎动物为研究高纬度动物群的演化提供了独特的机会。这些动物群也有助于我们了解中生代高纬度气候。
