Two Upper Jurassic–Lower Cretaceous palynological successions from the Qinghai-Xizang Plateau, China, are briefly introduced in this paper. The northern succession, from the Tanggula Mountains area, consists of three assemblage zones whereas the southern comprises two zones. Both of them are from marine sequences with diverse dinoflagellate cysts occurring in association. The positions of the J–K boundary are discussed and evaluated through comparison with the dinocyst stratigraphy. It shows that the first occurrences of Aequitriradites spinulosus and Cicatricosisporites sp. may be the best markers for the boundary from a miospore perspective. The peak occurrence of Dicheiropollis in the equatorial Tethys region might be significant for this boundary.
