Early Pleistocene Dicerorhinus sumatrensis remains from the Liucheng Gigantopithecus Cave, Guangxi, China

Abstract: The Liucheng Gigantopithecus Cave is very famous for its rich mammalian fauna and Gigantopithecus fossils. The Gigantopithecus Cave Fauna has been regarded as the typical Early Pleistocene fauna in South China. The majority of the fossils unearthed has been studied and published during the past decades. The only group remaining unpublished is the rhinoceros, which is studied in this paper. The rhino materials available today are only mandibles and lower cheek teeth. The dimensions of the tooth rows and the isolated teeth fall well within the range of the recent Dicerorhinus sumatrensis. Therefore, the rhino fossils from the Liucheng Gigantopithecus Cave can be referred to this living species. The reduced lower incisors and the U-shaped lingual contour of the mandible also support this taxonomic determination. The rhino materials from the Liucheng Gigantopithecus Cave represent the earliest known record of this species and the smallest Pleistocene rhinocerotid in China. [Copyright &y& Elsevier]
