| 摘 要： | 青藏高原北部雀莫错附近发现大量保存完好的伟齿蛤类等双壳类化石，包括Neomegalodon cornutus(sp．nov．)，Quemocuomegalodon orientus Yao et a1．，Q．longitatus Yao et a1．，Q．circularis(sp．nov．)，共生有Bakevellia praecursor(Quenstedt)等．据此，该含化石地层确定为上三叠统；指出它们属典型的特提斯动物群；并为修订伟齿蛤科的现行分类方案奠定了基础。

| Abstract: | Very abundant and well-preserved bivalves including Neomegalodon cornutus (sp. nov. ), Quemocuomegalodon oricntus Yao et al. , Q. longitatus Yao et al. and Q. circularis (sp. nov. ), associated with Bakevellia praecursor (Quenstedt), were found from the Quemocuo area, the north part of Qinghai-Tibet Plateau. Accordingly, the fossil-bearing rocks are now placed into the Upper Triassic. These bivalves refer to the Tethy fauna. On the basis of the well-preserved dentitions, a discussion on the classfica-tion of Megalodontidae is also involved. |
