文章报告了在广西崇左生态公园三合大洞中新发现的巨猿牙齿化石,这些新化石材料为研究巨猿演化及华南地区更新世动物群时代演化及环境变迁有着重要意义。三合大洞共出土巨猿牙齿56枚,除上犬齿,其他上、下颌牙齿种类齐全;从牙齿发育及磨损情况判断,这些材料代表了婴幼年、青少年、青壮年、中年及老年各年龄阶段的至少5个个体。测量了牙齿大小,并与其他的巨猿化石点的材料进行对比,认为三合大洞的巨猿牙齿与武鸣、巴马的巨猿有可比性。在此基础上,结合动物群组合特征及时代意义,探讨巨猿的牙齿大小时代演化趋势,同时提出存在的问题。
The article reports on the newly discovered giant ape dental fossils found in the Chonghe Ecological Park in Chongzuo, Guangxi. These new fossil materials are of great significance for studying the evolution of the great apes and the evolution of the Pleistocene fauna and the environmental changes in southern China. There are 56 teeth of great apes unearthed in Sanhe Dadong. In addition to upper canines, the other upper and lower jaws have many kinds of teeth. Judging from the development and wear of teeth, these materials represent all ages of infants, adolescents, young adults, middle-ages and seniors Of at least 5 individuals. The size of the teeth was measured and compared with the materials of other Great Apes fossils, suggesting that the giant ape’s teeth in Sanhe Cave were comparable to Wuming and Bama’s great apes. On the basis of this, combined with the characteristics of the fauna assemblages and the significance of the times, this paper discusses the evolutionary trend of the teeth age of the great apes and presents the existing problems.
