9315830 Hammer This award supports continued research on Triassic and Jurassic age vertebrate material collected in the Beardmore Glacier region of the Transantarctic Mountains. The fossils include Triassic synapsids and the first Jurassic dinosaurs from Antarctica. This continued funding is required because of the large amount of material that was collected during the previous field work and because of the time consuming nature of fossil preparation work. The collection to date has produced at least five taxa of Jurassic age, including a new large crested carnivorous dinosaur. Other dinosaur material includes portions of a prosauropod and teeth of a scavenging carnivore. In addition to the dinosaur material, other Jurassic animals identified include a pterosaur and a tritylodont synapsid. Early Jurassic fauna under study is one of only a few high latitude faunas known and so has considerable paleoclimatic significance. In addition, because Early Jurassic terrestrial vertebrate faunas are relatively rare, these fossils could provide significant information about the evolution of lineages between the Late Triassic and the Middle to Late Jurassic. Preparation of the Triassic material will follow the completion of the Jurassic material. ***

9315830锤子奖支持在横跨北极山脉的比尔德莫尔冰川地区收集的三叠纪和侏罗纪时代脊椎动物材料的继续研究。这些化石包括三叠纪突触体和来自南极洲的第一批侏罗纪恐龙。由于在以前的实地工作中收集了大量材料，而且化石准备工作非常耗时，因此需要继续提供资金。到目前为止，这些藏品已经产生了至少五个侏罗纪时代的分类群，其中包括一种新的大型羽冠食肉恐龙。其他恐龙材料包括原蜥脚类动物的部分和食肉动物的牙齿。除了恐龙的材料，其他被发现的侏罗纪动物包括一只翼龙和一只三齿突触。正在研究的早侏罗世动物群是为数不多的已知的高纬度动物群之一，因此具有相当大的古气候意义。此外，由于早侏罗世陆生脊椎动物相对罕见，这些化石可以为晚三叠世至中、晚侏罗世之间的谱系演化提供重要信息。三叠纪材料的准备工作将在侏罗纪材料完成之后进行。***
