| Abstract: | The Cretaceous outcrops are widespread in central part of Xizang. Transgression took place in a period from the latestage of early Cretaceous to early stage of late Cretaceous(Kf-Kl). Marine bivalvia are very flourishing. For the first time 4new species and 1 undefined species Laevitrigonia(Malagasitrigonia)gegyanensis, Paeudolimea, minima, Lucina grandiformisa, Crassatella(s. l. )comartum, Neithea(N.)sp.] of bivalvia fossils obtained from Gegya, Gerze and Painbo Nongchang area of Lhasa are de-scribed in this paper. |
