However, material of this group from the Upper Miocene of northern China is rare and easily to be confused with the similar taxa such as Konobelodon and Stegolophodon. The stratigraphy of this group is also unclear in China. Here we described the first mandible from northern China that can be definitely attributed to Tetralophodon, and erected a new species Tetralophodon euryrostris n. sp. Furthermore, we amended the previously reported tetralophodont gomphotheres from northern China. We attributed the type material of "Tetralophodon exoletus" to ?Paratetralophodon exoletus, the material from Lantian region ("Tetralophodon exoletus") to Paratetralophodon sp., and the material from the Qaidam Basin (Tetralophodon sp.) to Tetralophodon aff. xiaolongtanensis. We also discussed the stratigraphic ranges of the tetralophodont proboscideans from the Upper Miocene of China, that is, Tetralophodon aff. xiaolongtanensis from MN9, Tetralophodon cf. euryrostris from MN10, Konobelodon robustus from MN9 MN10, Paratetralophodon sp. from MN11, ?Paratetralophodon exoletus from MN12, and Stegolophodon licenti from MN13. This work is important for the study of the taxonomy and biostratigraphy of tetralophodont gomphotheres from the Upper Miocene of northern China.

While there is some consensus on key relationships among their members, on the basis of molecular- or morphology-based analyses, or combined approaches, many questions remain, and the bony labyrinth has shown considerable potential for the phylogenetics of this and other groups. Here we examine its shape in 29 species of living and fossil deer using 3D geometric morphometrics and cladistics. We clarify several issues of the origin and evolution of cervids. Our results give new age estimates at different nodes of the tree and provide for the first time a clear distinction of stem and crown Cervidae. We unambiguously attribute the fossil Euprox furcatus (13.8 Ma) to crown Cervidae, pushing back the origin of crown deer to (at least) 4 Ma. Furthermore, we show that Capreolinae are more variable in bony labyrinth shape than Cervinae and confirm for the first time the monophyly of the Old World Capreolinae (including the Chinese water deer Hydropotes) based on morphological characters only. Finally, we provide evidence to support the sister group relationship of Megaloceros giganteus with the fallow deer Dama.

Here, I reanalyse a maxilla containing M1-3 from the Lunan Basin, Yunnan Province, China. This element was initially assigned to a new tapiromorph species, Lophialetes yunnanensis, but is here placed in a new genus Lophiohippus within Pachynolophinae based mainly on the absence of mesostyles, the strongly oblique metalophs, the strong development of lophodonty, parastyles overlapping metastyles of preceding teeth and situated mesial to the paracone, and the fact that M3 is longer than wide and has a large and buccally deflected metastyle. Lophiohippus differs from European Anchilophus and Paranchilophus in that the parastyles are situated mesial or even slightly lingual, rather than mesiobuccal, to the paracones, and M3 is markedly relatively larger than M1. I further reanalyse Qianohippus magicus from the Shinao Basin of Guizhou Province, China, in which the complete dentition is known. Qianohippus is characterized by a molariform P2 and non-molariform P3-4; a relatively high degree of lophodonty; the absence of mesostyles; an angular bending in the protoloph on P3-M3 and the metaloph on M1-3 at the paraconule and metaconule, respectively; and weakly developed metastylid' on the lower cheek teeth. A cladistic analysis supports a close relationship between Lophiohippus yunnanensis and Paranchilophus, and suggests that Qianohippus is closely related to some derived pachynolophs. The appearance of the pachynolophins Lophiohippus and Qianohippus in China supports the existence of a biogeographical connection between Europe and Asia in the Middle-Late Eocene, and the dispersal route was probably along the Tethyan microcontinents in the south.
