摘　　要：对2004—2006年在湖北省郧西县黄龙洞发现的7枚更新世晚期人类牙齿进行了观测与分析,在此基础上与相关的化石人类及近代现代人类标本进行了对比。本研究发现:黄龙洞人类牙齿总体特征与现代人接近,同时也保留部分可能属于更新世晚期人类的特点,包括前部牙齿(侧门齿与犬齿)尺寸及粗壮程度都明显大于现代人。黄龙洞人类牙齿呈现的铲形门齿、双铲形门齿及臼齿釉质延伸说明,当时人类已经具有了东亚人群的典型牙齿形态特征。The morphological and metrical features of seven late Pleistocene human teeth found in Huanglong Cave, Yunxi County, Hubei Province, were compared with relevant fossil and recent human samples. Our work indicates that most of the dental features of the Huanglong Cave teeth resemble those of modem humans, with a few features also identified in the late Pleistocene humans. The occurrence of shoveling and double shoveling on the upper incisors, and enamel extension on the upper molar from the Huanglong Cave suggest that these humans already had typical dental morphological features of East Asian populations. This study also found a greater size and more pronounced robustness in the Huanglong Cave anterior teeth as compared to modem humans. Obvious damage and chipping caused by non-mastieatory utilization of teeth was also recognized.
