New cervid and bovid material from Yongdeng, Gansu Province, China, is described here. It should be attributed to Cervavitus cf. C. shanxius and 'Gazella' paotehensis. At least 12 mammal species occur at the Xingjiawan locality, and the coexistence of Stegodon sp., Chilotherium habereri, Chleuastochoerus stehlini, Cervavitus cf. C. shanxius, and 'G...

Faunal provincialism between the North and South parts of Eastern Asia is shown to have been in place since the late Eocene. This provincialism structured the mammalian dispersals across Eurasia for millions of years and provides insights into both palaeonvironments and palaeoclimate zonation. In addition, this study reveals the oldest record of a...

The cranial appendage (headgear) is an iconic structure of modern ruminants, and four of the five extant pecoran families display morphological and physiological specialties. They probably share one origin from the same genetic basis, whereas the evolution of the cranial appendages is still debatable, especially in consideration of fossil taxa lack...

Bovid material from Xishuigou, Tabenbuluk area, Gansu Province, China, is described here. The type material of ‘Eotragus’ halamagaiensis from the Halamagai Formation, Junggar Basin, Xinjiang Uygur Autonomous Region, China is reviewed as well. Both should be attributed to Turcocerus halamagaiensis comb. nov. The short and almost straight horn cores...

the taxonomy of Chinese Late Miocene Gazella fossils

Anatomic modification in evolution process of mammals was closely correlated with the environmental changes, and become the powerful evidence for reconstructing the palaeoenvironment shaped their evolution. Rhinocerotid fossils are important indicators of the ecosystems inhabited by the mammalian faunas. Here, we first described remains of two rhin...

Two Hipparion species, H. forstenae and H. hippidiodus from Gaojiashan locality in the Linxia Basin, Gansu, China are described in this paper, with the first presence of the former in the Linxia Basin. The lower cheek teeth of Hipparion from Gaojiashan bear deep ectoflexids, and after comparisons to other Chinese Hipparion fossils with deep ectofle...

Abstract A new skull of Urmiatherium intermedium (Bovidae, Artiodactyla) from the Linxia Basin, Gansu Province is described here. U. intermedium is a large Late Miocene bovid with an odd-looking horn apparatus, consisting of a pair of degenerate, closely situated horn-cores, and a large area of exostoses on the frontal and the parietal bones. Plent...

A completely preserved mandible of Leptobos from the Early Pleistocene mammalian fauna of Longdan, Gansu Province, China, is described here. The mandible has a long thin mandibular body, and a long mandibular diastema. The premolar row is short. The mandibular body forms an obtuse angle of about 120° with the mandibular ramus, while the angle of th...

Fossils of Gazella unearthed from the Linxia Basin, Gansu Province are studied in this paper. The fossils localities, Baihuacun (LX0205, 35°23′43.2″N, 103°29′45.2″E) and Shilei (LX0031, 35°25′19.7″N, 103°27′30.3″E), locate in Guanghe County, Linxia Hui Autonomous Prefecture, Gansu Province. The fossiliferous layers correspond to the upper part of t...

A new species, Eostyloceros hezhengensis sp. nov., is established based on a skull with its cranial appendages collected from the Late Miocene Liushu Formation of the Linxia Basin in Gansu Province, northwestern China. It is a large-sized muntjak with a distinct longitudinal ridge along the lateral margin of the frontal bone that joins the antler p...

Because few Upper Miocene localities have been discovered in South China, rhinoceros specimens from the Upper Miocene hominoid fauna of the Yuanmou Basin are critical for understanding the taxonomy and distribution of rhinoceroses of South China during this time interval. Here we report new specimens from this basin, including three isolated lower...
