神农架旧石器时代遗址犀牛洞是中国中南部犀牛的海拔最高的地方，也是千金牛科化石最南端和最丰富的地方，包括头骨、下颌骨、孤立的牙齿和后脑。这些材料可按以下特征命名：无切牙，下颌联合收缩，枕骨高，耳下通道闭合，鼻角和额角，鼻中隔部分骨化，前磨牙后牙和面颊牙齿釉质表面光滑等；除了其相对较短的四肢骨骼。在《中国》一书中，在过去的几十年里，所有更新世的非腔齿类双角犀牛都被归类为Dicerorhinus属。从今天的观点来看，他们中的大多数都应该被包括在斯蒂芬诺辛斯属中，因为迪克雷乌斯人在以下特征上与斯蒂芬诺斯人有很大的不同：体型较小，鼻中隔一般未骨化，耳下通道开放，门牙减少等。这是首次发现与大足兽-剑齿动物群有关的斯蒂芬诺希斯人，这是中国南部典型的更新世哺乳动物动物群。
The Rhino Cave, a Paleolithic site in Shennongjia, is the highest altitude locality of rhinoceros in the Middle-South part of China, and it is also the southernmost and the richest locality inStephanorhinus kirchbergensisfossils which include cranium, mandibles, isolated teeth and postcranials. These materials can be referred to the speciesStephanorhinus kirchbergensisaccording to the following characters: incisorless, mandibular symphysis contracted, occiput high, subaural channel closed, with nasal and frontal horns, nasal septum partially ossified, premolars hypsodont and cheekteeth with smooth enamel surface, etc.; except its relatively shorter limb bones. In China, all the Pleistocene non-Coelodontatandem-horned rhinoceroses were assigned to the genusDicerorhinusin the past decades. From today’s viewpoint, most of them should be included in the genusStephanorhinus, becauseDicerorhinusis quite different fromStephanorhinusin the following characters: smaller body size, generally unossified nasal septum, subaural channel open and with reduced incisors, etc. This is the first knowledge ofStephanorhinus kirchbergensisassociated withAiluropoda-Stegodonfauna, the typical Pleistocene mammalian fauna in South China.
