Abstract: During 1980~90's, some fossil lagomorphs were collected from Late Eocene of Erenhot, Urtyn Obo(=Erden Obo) and Haosiburdu Basin, Nei Mongol, by the teams of IVPP using screen washing technique. They are first discovered in these localities. The new discovery not only expanded the distribution of the lagomorphs in Asia, added new material of the lagomorphs and augmented the content of the faunas at the localities, but also played an important role in determining the ages of the fossiliferous beds in these localities. The undescribed specimen collected from Jhamo Obo by the Third Asiatic Expedition is also described here.
