摘要
笔者首次发现内蒙古阿拉善左旗地区井下早石炭世晚期有孔虫动物群，经研究计有１４属１８种，其中小有孔虫１２属１６种（１新属、新种），２属２种。这一有孔虫动物群的发现，除证明该地区存在早石炭世地层外，对当时岩相古地理面貌的分析。
The late Early Carboniferous foraminiferal fauna first discovered and described in this paper
was collected from Alxa Zuoqi, Nei Mongol. This foraminiferal fauna contains 18 species in 14
genera, including 1 new genus and species as listed below: Ammodiscus sp.,
Archaesphaera minima Suleimanov, A. squalida (Antropov), Eotuberitina reitlingerae A.D.
M. Maclay, Neimongollagena alashanica gen. et sp. nov., Palaeotextularia gibbosaeformis
(Reitlinger), Tetrataxis minima Lee et Chen, Endothyra? hemievoluta Lin, E. cf.
guangdongensis Li, Medocris brevisculus (Ganelina), M.ovalis (Vissarionova), Priscella
sp., Bradyina modica Ganelina, Archaediscus krestovikovi koktjubensis Rauser, A. sp.,
Asteroarchaediscus rugosus (Rauser), Eostaffella ikensis Vissarionova, Shouguanica sp.
The discovery of foraminiferal fauna in this region is of great geological significance, for it not
only shows the existence of Early Carboniferous strata, but also helps in the interpretation of
palaeogeographic environment at that time. It is concluded that the region then belongs to
“QILIAN SHALLOW SEA OR BAY”, and not “NORTH CHINA PENEPLATE OR OLDLAND”.
