Since the details of the Theromorpha-bearing beds of Sinkiang haveas yet not been fully outlined,we feel that it is too early to draw any reliablestratigraphical and pal(?)ntological conclusions now,but we mention the wealthof the fauna.The two specimens here described are all well preserved andnearly complete.According to the information supplied by Yuan,there arestill a considerable number of boxes unpacked.We hope to find more interest-ing finds so as to obtain a general view of the fauna in Sinkiang. pal(?)ntological seaking,the genera of the fauna so far recognizedare Dicynodon,Lystrosaurus and Chasmatosaurus(a Pelcosimia)(to be describedin the near future).No Cynodontia or other interesting forms are recorded.This strongly suggests that,as in the Karroo formation,Dicynodon andLystrosaurus also represent the most common and widely distributed animalsamong the other Theromorphan reptiles in Sinkiang. As far as the known forms in Sinkiang are concerned,no remarkableanatomical characters are found.All three genera are known in S.Africa.It therefore seems,that either a land connection between both existed or thatthe conditions between both during the Permo-Triassic time were extremelysimilar.  相似文献

严格言之,两次去新,于地质上均无重大收获,仅于天山南北麓地质,有局部的认识。惟由局部的认识,亦可得若干比较可靠之结论。此结论惟何,即天山两麓,中生代以後地层,发育伟大,且有一部情况特殊,实非再加以详尽研究,不足以探尽其奇胜。然此等地层中,虽有若干含有丰富之生物群,堪  相似文献
