摘要
该文首次报道景谷盆地介形类化石13属30种(其中19新种,1未定种)并建立3个介形类化石组合,三号构组以Potamocypris-Candoniella为代表的介形类化石组合,时代为中新世早期;回环组以Herpetocyprella-Metacypris为代表的组合,时代为中新世中晚期;大红猫村组以Leucocythere-Ily-ocypris组合为代表,时代为上新世。
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.
