ABSTRACTPI will recover important geochronological and paleoenvironmental information for asuite of ~50 Paleocene vertebrate fossil localities in the Nanxiong Basin of south China that are rapidly being destroyed due to high rates of agricultural and urban development. Given the accelerating development in this part of south China and the imminent retirement of the scientists who originally discovered these fossil localities, this proposal meets a key criterion for SGER funding - it has a severe urgency with regard to availability of, or access to data, facilities or specialized equipment. Magnetostratigraphic and chemostratigraphic methods will be applied to Paleocene deposits in the Nanxiong Basin to answer two fundamental questions. (1) Do the major biotic turnovers that mark the boundaries between Paleocene Asian land mammal ages coincide in time with themajor turnovers that mark the boundaries between Paleocene North American land mammal ages? (2) Do the Paleocene Asian land mammal age boundaries correlate to episodes of regional or global environmental change? This project will strengthen international collaborations between Chinese and American paleontologists, which is particularly important given the excellent vertebrate fossil records on each continent and the biogeographic connections that Asia and North America have shared during the Mesozoic and Cenozoic.

摘要南雄盆地古新世脊椎动物化石群约50处，由于农业和城市的高速发展，这些化石群正迅速遭到破坏，利用该项目将恢复这些化石群的重要年代学和古环境信息。 鉴于中国南方这一地区的加速发展以及最初发现这些化石地点的科学家即将退休，该提案符合SGER资助的一个关键标准-它在数据、设施或专用设备的可用性或访问方面具有严重的紧迫性。磁性地层学和化学地层学方法将应用于南雄盆地古新世沉积，以回答两个基本问题。 (1)标志古新世亚洲陆地哺乳动物年龄界限的主要生物更替与标志古新世北美陆地哺乳动物年龄界限的主要更替在时间上是否一致？ (2)古新世亚洲陆栖哺乳动物年龄界线与区域或全球环境变化事件相关吗？ 该项目将加强中美古生物学家之间的国际合作，这一点尤其重要，因为每个大陆都有出色的脊椎动物化石记录，亚洲和北美在中生代和新生代之间有着共同的地理联系。
