项目摘要
The early and middle Miocene (ca. 23 to 11 million years ago) witnessed an expansion of the world's tropical and subtropical forests, and an increase in the diversity and distribution of mammals that thrived in forests with low seasonality and high productivity. Apes flourished under these conditions in the Old World. The contraction of subtropical forests in the late Miocene in Eurasia resulted in a decline in the diversity and abundance of apes, and the rise of monkeys and other mammals able to survive in more open and seasonal habitats. Several fossil sites in southern China provide evidence of this critical transition. In this project, the fossil site of Shuitangba, Yunnan Province, China, will be investigated because it has yielded the abundant and well-preserved remains of many mammal species of terminal Miocene age (~6.1 mya). Among them are an ape and a monkey, the first such co-occurrence in the Miocene of Eurasia. Recovery and detailed study of the fossils by an international team of American and Chinese investigators will make possible the characterization of the paleoenvironment of Shuitangba and the nature and adaptations of the site's many species, especially its primates and carnivores. Direct comparison of the Shuitangba biota with others of similar age in eastern Asia will provide a clearer idea of the nature and pace of environmental evolution in the region.Shuitangba captures a unique snapshot of the transition from the widespread evergreen forests of the Miocene to the more heterogeneous and seasonal habitats that followed. This project thus promotes the understanding of an ecosystem poised at the tipping point of a major change. The Shuitangba fauna and environment provide an unusually clear picture of a distinctive regional ecosystem that contained long-established species alongside new arrivals. A better understanding of the adaptations of species within such ecosystems may shed light on the dynamics of modern unstable environments.This project fosters strong international collaboration with Chinese scholars, including advanced training for Chinese paleoanthropologists, paleobiologists, and fossil preparators, and promotes public science education in China through media coverage and development of museum displays. A junior US scientist will be integrally involved in the research, and US undergraduate students also will receive substantial participatory research training.
早中新世和中中新世(约。2300万至1100万年前),见证了世界热带和亚热带森林的扩张,以及在低季节性和高生产力的森林中茁壮成长的哺乳动物的多样性和分布的增加。猿类在旧大陆的这些条件下繁衍生息。中新世晚期欧亚大陆亚热带森林的收缩导致猿类的多样性和丰富度下降,猴子和其他哺乳动物能够在更开放和季节性的栖息地生存。中国南方的几个化石遗址提供了这一关键转变的证据。 在本项目中,将对中国云南省的水塘坝化石遗址进行调查,因为该遗址已发现大量保存完好的中新世末期(约6.1百万年)哺乳动物物种的遗骸。其中有一只猿和一只猴,这是欧亚大陆中新世第一次同时出现。由美国和中国调查人员组成的国际团队对化石的恢复和详细研究将使描述水塘坝的古环境以及该遗址许多物种的性质和适应性成为可能,特别是灵长类和食肉动物。通过将水塘坝生物群与东亚其他类似年代的生物群进行直接比较,可以更清楚地了解该地区环境演变的性质和速度。水塘坝捕捉到了从中新世广泛分布的万年青森林到随后更异质和季节性栖息地过渡的独特快照。因此,该项目促进了对处于重大变化临界点的生态系统的理解。 水塘坝的动物群和环境提供了一个独特的区域生态系统的异常清晰的画面,其中包括长期存在的物种和新来的物种。 更好地了解物种在这种生态系统中的适应性可能会揭示现代不稳定环境的动态。该项目促进与中国学者的强有力的国际合作,包括对中国古人类学家,古生物学家和化石鉴定员的高级培训,并通过媒体报道和博物馆展览的发展促进中国的公共科学教育。 一名美国初级科学家将全面参与研究,美国本科生也将接受大量的参与性研究培训。
