摘要
简述了4个双壳类化石组合特征及沉积环境,描述了双壳类2新属(Sichuatrigonia, Pseudoburmesia)和11新种(包括新亚种).
The strata of Upper Triassic is well-developed in Maantang area, Jiangyou, Sichuan, with continuous sections and various genera and species of fossils. This paper makes a study of the rich fossil bivalves in this area, with description of 2 new genera (Sichuantrigonia, Pseudoburmesia), 9 new species and 2 new subspecies, and publication of major fossil bivalve photos; in addition, a brief account is also given on the characteristics of fossil bivalve assemblages and the sedimentary environment. This study should be of theoretical and practical significance to subdivision and correlation of the Upper Triassic strata in the northwestern part of the Sichuan Basin, and also to the understanding of faunal characteristics.
