This project will continue a survey and inventory of the famous Late Cretaceous Flaming Cliffs deposits in the Gobi Desert, Mongolia, site of the Central Asiatic Expeditions in the 1920s. Three previous expeditions by the AMNH has succeeded in recovering a wealth of well-preserved tetrapod vertebrates, especially theropod dinosaurs, mammals, and a new lineage of extraordinary flightless birds with mole-like adaptations for digging. These expeditions have also mapped old and new localities using GPS. Specimen and locality/geological information for the 10,000 specimens will be entered in a computer database. Cooperation with Mongolian authorities and scientists is excellent and includes field work in Mongolia and long-term study visits of Mongolian scientists to the AMNH. %%% This project will continue a survey of the fossil mammals, reptiles, amphibians and birds from the famous Late Cretaceous dinosaur beds in the Gobi Desert, Mongolia. This survey is revisiting the sites of the Central Asiatic Expeditions in the 1920s, which first discovered dinosaur egg nests and other important fossils. Three previous expeditions by this current survey team has succeeded in recovering a wealth of well-preserved fossil vertebrates, especially theropod dinosaurs, mammals, and a new lineage of extraordinary flightless birds with mole-like adaptations for digging. Cooperation with Mongolian authorities and scientists is excellent and includes field work in Mongolia and long-term study visits of Mongolian scientists at the American Museum in New York. Study of the fossils recovered by these expeditions will help elucidate the nature of dinosaur extinctions and climate change 65 million years ago.

本项目将继续调查和盘点著名的 晚白垩世火焰崖沉积在戈壁沙漠， 蒙古，20世纪20年代中亚探险队的所在地。 AMNH之前的三次探险成功地恢复了 大量保存完好的四足脊椎动物， 兽脚亚目恐龙，哺乳动物，以及一个新的 不会飞的鸟，有鼹鼠般的挖掘适应性。 这些 探险队还利用全球定位系统绘制了新旧地点的地图。 10，000个样本和地点/地质信息 样本将输入电脑资料库。 合作 蒙古当局和科学家是优秀的，包括 在蒙古的实地工作和蒙古人的长期考察访问 科学家向AMNH。 %%% 该项目将继续对哺乳动物化石进行调查， 著名的晚白垩世的爬行动物、两栖动物和鸟类 蒙古戈壁沙漠的恐龙床。 本次调查是 重新访问中亚探险队的网站， 20世纪20年代，首次发现恐龙蛋巢和其他 重要化石 在此之前的三次探险 调查小组成功地恢复了大量保存完好的 脊椎动物化石，特别是兽脚类恐龙，哺乳动物， 一种新的不会飞的鸟的血统， 适应挖掘。与蒙古当局的合作， 科学家是优秀的，包括在蒙古的实地工作， 蒙古科学家在美国的长期研究访问 纽约的博物馆。 对这些化石的研究 探险将有助于阐明恐龙进化的本质 和气候变化之间的关系
