Abstract: This paper reports a new tillodont species, Yuesthonyx tingae gen. et sp. nov., belonging to a new family, Yuesethonychidae. The new taxa is created based on the materials collected from the Late Paleocene Dazhang Formation of the Tantou Basin, Henan Province, in 1978. The associated mammal fossil in the Dazhang Formation is a mandible of pseudictopid (Anagalida) (Tong and Wang, 1980). We also briefly review the Asian tillodonts and noticed the tillodonts were diversified during Early Paleocens.
