| Abstract: | For lacking of absolute dating, and because of the strong mammalian faunal endemism, the Chinese late Neogene has long been subdivided into mammalian ages mostly based on isolated local faunas by evolutionary stages of fossil taxa. The correlation with European stages and or mammalian units remains unsatisfied. We report the recent advances of the land mammal biochronology of late Neogene based on fossils found from continuous sections located at Lantian, Shaanxi Province and Lingtai, Gansu Province. There recognized three biozones for the late Miocene by fossils from the Bahe and Lantian formations, and three biozones for Pliocene on the data from Lingtai. The detailed biochronology work in combination with paleomagnetic data may improve the precision of correlation in the continental scale. |
