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 ectoflexids, the mandibles with deep ectoflexids on the lower premolars suggest their attributions to H. forstenae. The presence of a deep ectoflexid on p2 may be interpretable as an intraspecifically variable feature in H. forstenae, and can also be found in H. dermatorhinum. Besides the Hipparion material, at least 8 species of large mammals occur at the Gaojiashan locality, including Adcrocuta eximia, Chilotherium wimani, Shansirhinus ringstroemi, Eucladoceros cf. proboulei, Palaeotragus cf. coelophrys, Giraffidae gen. et sp. indet., and the previously studied Promephitis hootoni and Eostyloceros hezhengensis. Although the sample from Gaojiashan shares five species with the Yangjiashan fauna, the Gaojiashan fossil assemblage may date to the Baodean because of the presence of H. forstenae. The overall taxonomic composition of the Gaojiashan assemblage at least suggests an approximate Baodean age, which would imply survival of C. wimani into the Baodean of the Linxia Basin. © 2017 Informa UK Limited, trading as Taylor & Francis Group

Tetralophodont gomphotheres, i.e., Tetralophodon, Paratetralophodon, and Anancus, show significant morphological diversity and are of great importance for the biostratigraphy of the Upper Miocene. 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. © 2017 Elsevier Ireland Ltd Elsevier B.V. and Nanjing Institute of Geology and Palaeontology, CAS.

Gomphotherium is a stem taxon of Elephantida that was widespread in Africa, Eurasia, and North America during the Miocene. However, the evolution of this genus is greatly debated because of morphological variation among the species of Gomphotherium. In the present work, we describe a cranium and accompanying material of Gomphotherium from the late middle Miocene Hujialiang Formation of Linxia Basin, China. The new material shows dental similarities to G. subtapiroideum from the middle Miocene of Europe; however, it displays some cranial, mandibular, and dental feature combinations that are distinct from the known species of Gomphotherium. Therefore, a new species, G. tassyi, is established. We further study the phylogeny of Gomphotherium by cladistic analysis and recognize four groups. The most basal ‘G. annectens group’ is a paraphyletic group that includes G. annectens, G. cooperi, G. sylvaticum, and G. hannibali. The African taxa, G. libycum and G. pygmaeus, constitute a monophyletic group that has not been named. The ‘G. angustidens group’ is a monophyletic group that includes G. inopinatum, G. mongoliense, G. connexum, and G. angustidens. In addition, the ‘derived Gomphotherium group,’ which includes G. subtapiroideum, G. tassyi, G. wimani, G. browni, G. productum, and G. steinheimense, was widely distributed in Eurasia and North America during the middle and late Miocene. http://zoobank.org/urn:lsid:zoobank.org:act:28B89A74-7FF6-41DB-BA3C-C4CDD200A30F SUPPLEMENTAL DATA—Supplemental materials are available for this article for free at www.tandfonline.com/UJVP Citation for this article: Wang, S.-Q., Y.

Here we describe a new species of Konobelodon Lambert, 1990 – a poorly known tetralophodont shovel-tusked proboscidean – from the Late Miocene of the Linxia Basin, China. Detailed osteological anatomies of skulls, teeth, and partial postcranial bones of the new taxon, Konobelodon robustus n. sp., are described and detailed morphological comparisons with the other species of Konobelodon (K. atticus (Wagner, 1857) = Mastodon grandincisivus, Schlesinger 1917, and K. britti (Lambert, 1990)) and other gomphotheres are conducted. The skull and jaw-closing muscles of a juvenile individual of the new species are reconstructed and the body mass is estimated based on its limb bones. Phylogenetic analysis of genera within Elephantimorpha results in three most parsimonious trees, of which two support a sister-group relationship between Konobelodon and Platybelodon, within a monophyletic Amebelodontinae. The new results enhance our knowledge on the anatomy and phylogeny of Konobelodon, and indicate pronounced diversification and strong parallel evolution in the amebelodontines. © Publications scientifiques du Muséum national d’Histoire naturelle, Paris.

The skull and mandible of a Late Miocene fossil pig, Chleuastochoerus, are compared morphologically with those of extant pigs and peccaries, and subjected to a functional analysis. The presence of a rostral bone in the skull and relatively strong rostral muscles indicates that Chleuastochoerus possessed considerable digging ability, though the relatively narrow occipital surface and the shortness of the skull would have restricted the range of motion through which the skull could be swung. The distinctive pre-zygomatic plate and over-canine arch-niche may have played a role in protecting the skull and canines during digging. The massive masticatory muscles, reconstructed based on well-developed parietal and zygomatic crests, would have enabled the mouth to close quickly and contributed to moving the mandible both longitudinally and laterally. The configuration of the cranio-mandibular joint and its relatively high position show clearly that Chleuastochoerus was capable of both crushing and grinding movements during mastication. The comparatively simple structure of the crown surfaces of the cheek teeth suggests that the food of Chleuastochoerus may have been softer than that of extant suids. The diet of Chleuastochoerus is postulated to fall between those of true forest pigs and open habitat pigs, and the habitat of Chleuastochoerus to be relatively humid forest edge or nearby areas of open steppe. © 2013 Science China Press and Springer-Verlag Berlin Heidelberg.

In this paper, we report on abundant fossils of Platybelodon from the Middle Miocene of the Linxia Basin, China. Most of the fossils were discovered at two localities (Laogou and Zengjia) in the upper Middle Miocene Hujialiang Formation, and possess derived characters for the genus, including a relatively slender upper incisor, the development of a transverse ledge on the narrowest part of the mandibular symphysis, narrow, elongate and hypsodont third molars, the development of fourth loph(id)s on the second molars, and the development of small enamel conules and cementum in the interloph(id)s. Following comparisons with other Eurasian platybelodonts, we assign these remains to Platybelodon grangeri, and demonstrate that they are morphologically intermediate between P. grangeri from the Tunggurian localities of Tarim Nor and Platybelodon Quarry in Inner Mongolia. We suggest that the locality of Laogou may be younger than that of Zengjia, based on the occurrence of platybelodonts showing a suite of more derived characters. In addition, we assign two further specimens of Platybelodon from the lower Middle Miocene Dongxiang Formation of the Linxia Basin to Platybelodon danovi, owing to their retention of plesiomorphic characters distinguishing them from other Linxia Platybelodon fossils. Based on a cladistic analysis, we propose an evolutionary sequence of platybelodonts in Eurasia, and discuss potential functional adaptations. © 2013 S. Wang et al.

A new species of the bovid Shaanxispira, from the upper Miocene deposits of the Linxia Basin, Gansu Province, China, is described here. Shaanxispira is endemic to Northern China and was previously known only from the Lantian area, Shaanxi Province, by two species, S. chowi and S. baheensis. The new species, S. linxiaensis nov. sp., is of early Bahean in age, slightly older than the species from the Lantian area. The horn-cores of the new species are more derived, with large wing-shaped antero-medial keels, suggesting the occurrence of a different lineage of Shaanxispira in the Linxia Basin. Although Shaanxispira has homonymously twisted horn-cores, it is not closely related to other late Miocene bovids with homonymously twisted horn-cores, like Oioceros and Samotragus. Its phylogenetic status is still in debate, but might be more closely related to the late Miocene "ovibovines." Copyright © 2014 Magnolia Press.

Though rarely found, chalicotheres have long been considered as indicators of wooded environment because of their unique anatomical structure and inferred ecological habits. A juvenile skull of a chalicothere with its articulated mandible was unearthed from the Duikang locality, Guanghe County, Gansu Province, China. This specimen can be identified as Ancylotherium sp. based on its short symphysis, shallow mandible, high crown and large size of upper molars, obvious crochets on upper milk teeth, complex structure of DP2 and dp2, and developed metastylids on the lower milk teeth. This rare skull differs from all other known species of the genus Ancylotherium. Nonetheless, existence of Ancylotherium in China is confirmed without doubt; at least five species in China (from Gansu, Sichuan, Shanxi and Shaanxi provinces respectively) can be attributed to this genus. Ancylotherium and its contemporaneous faunal components at the Duikang locality, together indicate a subarid steppe environment with small patches of forest in the Linxia Basin during the Early Pliocene. © 2012 Elsevier Masson SAS.

The Lower Pliocene of the Linxia Basin in Gansu Province is one of only a few representative sections for the Early Pliocene sedimentary records in northern China, and even in East Asia. Recently, abundant mammalian fossils were found from the base of red clays of the Lower Pliocene Hewangjia Formation at Duikang in Guanghe County within this basin. Previously, the Pliocene mammals were sparsely found in China, and most were collected from fluvial and lacustrine deposits in the eastern Loess Plateau. Mammals from the widely distributed Pliocene Hipparion Red Clay are less in number. The known fossils from Duikang include 20 species and belong to the Shilidun Fauna. Their faunal components are similar to the Early Pliocene Gaozhuang Fauna from Yushe, Shanxi. On the other hand, some taxa from Duikang have not been found in the Gaozhuang Fauna, are slightly more primitive in evolutionary level, and appeared mainly in the Late Miocene. As a result, the age of the Duikang fossils may be slightly earlier than that of the Gaozhuang Fauna and closer to the lower boundary of the Pliocene. The Duikang fossiliferous bed is 0.8 m above the top of the Late Miocene Liushu Formation, and the first occurrence of the three-toed horse Hipparion pater can be regarded as a biostratigraphical marker of the Miocene/Pliocene boundary.conclusion, Duikang is an ideal candidate locality to establish as the stratotype of the lower boundary of the Chinese terrestrial Pliocene.

Amebelodontidae is the most taxonomically and morphologically diverse group of proboscideans. However, relative to the morphological variation of the mandible and mandibular tusks, ecological and phylogenetic differentiations within Amebelodontidae have been largely debated. Here we evaluate a middle Miocene fossil accumulation of a new amebelodontid, Aphanobelodon zhaoi gen. et sp. nov. This species lacks upper tusks, which is unique in elephantiforms. The mandible and mandibular tusk morphologies of A. zhaoi are similar to those of the genus Platybelodon, which is the typical representative of one of the two main amebelodontid branches (the other branch is represented by Amebelodon). We suggest that Amebelodon potentially used its mandible and mandibular tusks to dig for food in relatively hard substrates; whereas Platybelodon is more specialized and possibly used its mandibular tusks for cutting soft vegetation. Aphanobelodon zhaoi morphology indicates that it is an offshoot of the platybelodont clade within Amebelodontidae, because it has primitive undifferentiated states of the mandible and mandibular tusks. Cladistic analysis indicates that Aphanobelodon, Platybelodon and Torynobelodon comprise a monophyletic group within Amebelodontidae. This study enhances our knowledge regarding proboscidean evolutionary history in terms of morphology, taxonomy and biology. http://zoobank.org/urn:lsid:zoobank.org:pub:8F30BAC7-4245-4952-BFCF-884E3DB839F6 © The Trustees of the Natural History Museum, London 2016.
