西藏岗巴地区的白垩纪地层,最早由海登(H.Hayden,1903—1904)进行过调查, 其后杜维叶(Douville,1916)对该区的双壳类化石进行了最早的描述,但属种极少,资料零星。1976年文世宣对这一地区的双壳类化石也作了研究,描述的有 Vepricardium?, Praeradiolites,Biradiolites,Bournonia,Inoceramus(Endocostea),Inoceramya?, Camptonectes(C.),Neithea(N.),N.(Neitheops),Pycnodonte(P.),P.(Phygraea), Aetostreon,Amphidonte,Pleuromya,Plectomya?等15属(包括亚属),近20多种(包括
The Cretaceous strata in the Gamba area of Tibet were first investigated by H. Hayden (1903-1904). Earlier, Douville (1916) described the bivalve fossils in this area, However, very few species, sporadic data. Studies of bivalve fossils in this area were also published by the 1976 World Wide Scripture and described Vepricardium®, Praeradiolites, Biradiolites, Bournonia, Inoceramus (Endocostea), Inoceramya®, Camptonectes (C), Neithea (N.) 15 genera (including subgenus) such as N. (Neitheops), Pycnodonte (P.), P. (Phygraea), Aetostreon, Amphidonte, Pleuromya, Plectomya ?, nearly 20 species
