These are the Kekemaideng, Halamagai, Suosuoquan and Ulunguhe formations. The contact relationships and biochronology of these rock units are discussed. The Kekemaideng beds are considered to be a formation of probably equivalent to middle Miocene Tunggur Fm. in age. The farm from the Halamagai Fm. is correlative to early coddle Miocene Tongxin fauna. The lower part of the Suosuoquan Fm. is younger than Tabenbulukian and probably of earliest Miocene. The Uunguhe Fm. in itS current usage is a mixture of sediments with different lithologies and different ages ranging from Cretaceous to Oligocene and should therefore be redefined.展开更多
Paraceraterium sui sp.nov. is represented by a lower jaw collected at Loc.20004 (46°35.779′N , 87°43.818′E) of Saerduoyila, Halamagai Village, Fuhai County, Xinjiang Uygur Autonomous Region.

The new species is similar to the type species of the genus, P. bugtiense , in general morphology of the mandible and teeth, but differs from the latter in larger size, the proportionally deeper horizontal ramus, the more anteroventrally curved symphysis and the much deeper trenched dorsal surface of symphysis. The associated small mammals indicates an age of Late Oligocene. The occurrence of Para ceratherium sui demonstrates that the genus Paraceratherium erected by Forster Cooper, based on the lower jaw from Pakistan, is a valid taxon different from Indricotherium .展开更多
