【Abstract】 The bryozoans dealt with in the present paper were found from the Upper Carboniferous Amushan Formation in Bayan Bulag, Xi Ujimqin Qi, belonging to 9 genera and 18 species （including 2 new species）. The bryozoan specimens are generally well preserved, especially in the section of 7p₃₂ about 1.5 km NNE of Holt Sum （Temple）, with altogether 18 species identified as follows: Fistulipora pseudolifica Yang et Lu, Prismopora sp. 1, Prismopora sp. 2, Prismopora kuzuensis Sakagami, Goniocladia bayanbulagensis sp. nov., G. deformis sp. nov., Ligulockema cf. meridianus （Etheridge）, Rhombotrypella darvasica Gorjunova, Fenestella tuberculifera Schulga-Nesterenko, F. rarispinata Sch.-Nest., F. ninae Viskova, F. sinoregulata Yang et Lu, Folypora tenuata Schulga-Nesterenko, P. subborealis Sch.-Nest., P. abundans Sch.-Nest., P. gzhelensis Sch.-Nest., Tharnniscus cf. dubius （Schlotheim） and Penniretepora cf. beresovensis （Morozova）.Among these species, Fistulipora pseudolifica Yang et Lu and Fenestella sinoregulata Yang et Lu were originally described from the Upper Carboniferous Taiyuan Formation of Qilianshan, Qinghai Province; Fenestella ninae Viskova and Potypora abundans Schuiga-Nesterenko have been reported from the Kasimovian Stage of the Russian Platform; Fenestella gzhelensis Sch.-Nest. and Polypora subborealis （Sch.-Nest.） were originally described from the Gshelian Stage of the Russian Platform;Penniretepora beresovensis was originally reported by Morozova from the Upper Carboniferous in the Don River Basin of the USSR; Polypora tenuata Sch.-Nest., Fenestella tuberculifera Sch.-Nest. and Fenestella rarispinata Sch.-Nest. were found from the Asselian Stage and Rhombotrypella darvasica Gorinnova was described by Gorjunova from the Sakmarian Stage of Darvas, Pamir. Besides these forms, some Permian bryozoans such as Liguloclema cf. meridianus （Etheridge）, etc., are very similar to the Thailand specimens that were also considered to be the Permian age by Sakagami （1973）. The genus Liguloclema was established by Crockford （1957） based on the material from the Nookanbah Series of western Australia, while the genus Liguloclema was first found from the Carboniferous. Thamniscus cf. dubius （Schlotheim） is very similar to the Japanese specimen described from the Parafusulina zone by Sakagami （1961）.According to the faunal analysis, therefore, the present bryzoan fauna is considered as late Late Carboniferous in age.更多还原
