The Lower Cretaceous strata are well developed and widely distributed in the Liupanshan Basin, Ningxia Hui Autonomous Region, NW China. A variety of spores and pollen have been discovered, whereas few megafossil plants have been reported. In the present study, a new cheirolepidiaceous species, Pseudofrenelopsis liupanshanensis, is described from the Lower Cretaceous Naijiahe Formation of the Liupanshan...
A total of 41 spore species and 63 pollen taxa, including seven angiosperms, were identified from 24 samples of the Early Cretaceous succession (latest Barremian to Aptian) at the Wulan Section in the east part of the Yingen-Ejinaqi Basin, Inner Mongolia, China. In a stratigraphically upward order, three types of palynomorph assemblages were identified. Palynological assemblage I (PA I) was dominated...
