Diverse and abundant ostracoda fossils were found in the rosoft-com:office:smarttags" />Gyirong Basin in the south of the Tibet. The research is based on 37 species of ostracoda including 8 undefined ones that belong to 9 generas. On the basis of the characteristics of ostracoda fossil succession, the ostracoda fauna in this area can be divided into 2 ostracoda assemblages in ascending order as follows: Ilyocypris pentanoda-Qaidamothere vena assemblage and Leucocythere mirabilis-Leucocytherella assemblage. The authors compared the ostracoda assemblages of Oma Formation with those worldwide at the same stratum and concluded that the age of Oma Formation is Late Miocene to Early Pleistocene.rosoft-com:office:office" />
