新近的古生物、古地磁和碳同位素研究为中国陆相古新统-始新世界线的确定提供了新的证据，支持中国陆相古新统-始新世界线位于湖南衡阳盆地岭岔组底部和内蒙古二连盆地诺蒙组上部。根据哺乳动物和介形类生物地层学资料，该界线也可大致与广东三水盆地的宝月组和华永组、江西的清江组和新余组、江苏北方的阜宁群第四组和戴南组以及新疆吐鲁番盆地的大埔组和十三间房组的接触面进行对比。
Recent paleontological, paleomagnetic and carbon isotopic investigations have provided new evidence supporting placement of the Chinese terrestrial Paleocene–Eocene boundary at the base of the Lingcha Formation in the Hengyang Basin, Hunan Province, and within the upper part of the Nomogen Formation in the Erlian Basin, Inner Mongolia. Based on mammalian and ostracod biostratigraphic data, the boundary can also be roughly correlated with the contacts between the Baoyue and Huayong formations in the Sanshui Basin of Guangdong, the Qingjiang and Xinyu formations of Jiangxi, the Fourth Formation of the Funing Group and the Dainan Formation in northern Jiangsu, and the Dabu and Shisanjianfang formations in the Turfan Basin of Xinjiang.
