This paper is resulted from a systematic study of sporo-pollen of Ordos Basin of Northwest China has been found. Single spore assemblage in the Taiyuan Formation contains abundant Pteridophic and Pteridosperm spores and a few Gymnosperm pollen. 11 new species are described. New sporopollen taxa include, Punctatisporites gansuensis, Auritulinasporites ningxiaensis, Gulisporites discersus, Trivolites scabratus, Psomospora anulatus, Gravisporites rugu- laris, Velamisporites breviradidlis, Murospora strialatus, Foveomonoletes foveolatus, Cy- clogranisporites microtriagulus (comb. n.), Cycadopites pachyrrhachis (comb. n.) and Punatatisporites sp., Tantillus sp., Converrucosisporites sp., Columnisporites sp.. and Zono- spheridium reticulatoides and Z. granuloides of Acritarchs. There are some differences between spore assemblages of eastern and western parts of Ordos Basin. Western part is characteristic by more abundance of cingulum spores. The age of the microfossil is considered to be of the Late Carboniferous.
