Continued Research on the Vertebrate Paleontology of the Upper Fremouw (Early-Middle Triassic) and the Falla Formations (Jurassic), Beardmore Glacier Region, Antarctica

9315830 Hammer 该奖项支持对在横贯南极山脉的比尔德莫尔冰川地区收集的三叠纪和侏罗纪脊椎动物材料的继续研究。 这些化石包括三叠纪合弓动物和来自南极洲的第一批侏罗纪恐龙。 由于之前的实地工作收集了大量材料，而且化石制备工作非常耗时，因此需要持续提供资金。 迄今为止，该收藏已产生至少五个侏罗纪时代的类群，其中包括一种新的大型冠肉食性恐龙。 其他恐龙材料包括原蜥脚类动物的部分和食腐肉食动物的牙齿。 除了恐龙材料外，还发现了其他侏罗纪动物，包括翼龙和三亚齿类合弓动物。 正在研究的早期侏罗纪动物群是已知的少数高纬度动物群之一，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群相对稀少，这些化石可以提供晚三叠世至中晚侏罗世间谱系演化的重要信息。 三叠纪材料的制备将在侏罗纪材料完成之后进行。 ***

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. ***
