| Abstract: | The ostracods studied in this paper were collected in 1989 from the Neogene strata of the JingguBasin, Yunnan,containing 13 genera and 30 species (including 19 new species and 1 indeterminablespecies). According to their vertical distribution, 3 assemblages are recognized in ascending order,namely, Potamocyoris--Candoniella Assemblage, Herptocyprella--Metacypris Assemblage and Leucocythere-I-lyocypris Assemblage, which occur in the Sanhaogou, Huihuan and Dahongmaocun Formations respec-tively. Based on these assemblages,the Sanhaogou and Huihuan Formations may be assigned to early tomiddle late Miocene,while the Dahongmaocun Formation may be Pliocene. |
