New discoveries of Gigantopithecus blacki teeth from Chuifeng Cave in the Bubing Basin, Guangxi, south China.
Ninety two Gigantopithecus blacki teeth have recently been recovered in situ at Chuifeng Cave in the Bubing Basin, Guangxi, south China. The hominoid teeth are associated with a typical early Pleistocene fauna. In comparison with Gigantopithecus of known provenience, for which classification is problematic, the Chuifeng sample can be allocated definitively to G. blacki. The new collection represents the largest sample of this species known, with the exception of the material from Liucheng. Statistical analysis of the mammal fauna indicates that G. blacki is one of the dominant elements, comprising 9% of the fauna. Eleven teeth (12% of the sample) of G. blacki are diagnosed as having caries. In addition, wear on M(3) shows that G. blacki was adapted to consume tough or fibrous food and this wear may potentially imply relative longevity. Further study of this large sample of Gigantopithecus will provide additional insight into the paleobiology of this extinct hominoid.
