Miocene mammalian faunas from Wushan, China and their evolutionary, biochronological, and biogeographic significances
چکیده انگلیسی
We report Miocene mammalian faunas from three nearby localities: Kangping, Nanyu, and Yangping, in the Wushan Subbasin, Gansu Province, China. From the Kangping locality, we identified four species, Platybelodon grangeri, Hispanotherium wushanense n. sp., Kubanochoerus sp., and Turcocerus cf. kekemaidengensis, which indicate that this fauna can be correlated with MN7/8. From the Nanyu locality, we identified Platybelodon aff. tongxinensis, which, together with the previously reported specimens of Gomphotherium wimani and Micromeryx cf. flourensianus, enables us to correlate this fauna with MN6. The Yangping locality is found to be early Miocene in age based on the presence of cf. Gomphotherium sp. This occurrence is the earliest record of proboscideans in China, and thus represents the “Proboscidean Datum Event”. Evolutionary trends of Platybelodon and Hispanotherium are figured and discussed. The possibility of a geographic boundary associated with the eastern and western differentiation of species of Turcocerus and bunodont listriodonts in China is also evaluated. This boundary was consistent with the major division of the eastern and western mammalian faunas of the middle Miocene in China. The localities in Inner Mongolia suggest a large area with transitional habitats.
