英文摘要Cimolodontan multituberculates are common in the Late Cretaceous and Paleocene of central Asia; they are rarely known from regions south of the Mongolian plateau. Here, we report a new genus and species of multituberculate, Erythrobaatar ganensis gen. et sp. nov., from the Late Cretaceous of Ganzhou, Jiangxi Province, central China, representing the southernmost record of Cretaceous multituberculates in Eurasia. The new species is based on two well-preserved specimens that include cranial and postcranial materials. With a cranium and dentary length of 83 and 66 mm, respectively; it is one of the largest known Cretaceous multituberculates from Eurasia. The present work focuses on the description of the craniodental morphology of the new species, in comparison with that of other Late Cretaceous and Paleogene cimolodontans in order to establish the new taxon. Erythrobaatar ganensis is most closely related to Yubaatar zhongyuanensis and Yubaatar qianzhouensis in the shape and size of the skull and teeth. Phylogenetic analyses place the new species within Taeniolabidoidea, which consists mostly of Late Cretaceous and Paleogene cimolodontans from Asia and North America. The new material also sheds light on tooth replacement, reduction, homologies, and occlusion of multituberculates with a focus on cimolodontans.
