广西壮族自治区扶绥县早更新世早期岩梁洞沉积物中发现了大量与巨猿（Gigantopithecus blacki）共生的犀牛牙齿化石，将其命名为Rhinocerosfusuiensissp. nov.（犀牛科，奇蹄目，哺乳目）。新种在形态上与现存种Rhinocerossondaicus（Javanrhinoceros）相似，但与Rhinocerosfusuiensissp. nov.是现生松达古猿R. sondaicus的潜在祖先，也是华南早更新世巨猿-中国乳齿象动物群的共同成分。其他早更新世遗址的犀牛遗骸（例如，中国南方的龙骨坡洞和墨灰洞以及缅甸的伊洛瓦底江沉积物也被归入新种。R.扶绥亚种nov.提供了中国南方第四纪生物地层学的重要信息，并暗示中国南方早更新世是犀牛类重要的演化和动物地理中心。
Abundant dental fossils of Rhinoceros, associated withGigantopithecus blackifrom the early Early Pleistocene Yanliang Cave deposits in Fusui County, Guangxi Zhuang Autonomous Region of southern China, are described asRhinocerosfusuiensissp. nov. (Rhinocerotidae, Perissodactyla, Mammalia). The new species is morphologically more similar to the extant speciesRhinoceros sondaicus(Javan rhinoceros) than to other species of the genus, but differs fromR. sondaicusin bearing a slightly smaller size, a complete protoloph on P2 after heavily worn, a better developed crochet which is close to the protoloph, and a more curved ectoloph.Rhinoceros fusuiensissp. nov. is considered as the potential ancestor of the livingR. sondaicusand the common element of the Early PleistoceneGigantopithecus-Sinomastodonfauna in southern China. TheRhinocerosremains from other Early Pleistocene sites (e.g., Longgupo Cave and Mohui Cave in southern China and Irrawaddy sediments in Myanmar) are also assigned into the new species. The discovery ofR. fusuiensissp. nov. provides important information on Quaternary biostratigraphy in southern China, as well as implicating southern China as a significant evolutionary and zoogeographic center forRhinocerosduring the Early Pleistocene.
