Abstract: In 1976, a less-than-complete skull cap was found in Jingchuan, Gansu Province by Liu Yulin. Previous studies showed that this cranium belonged to a female about 20 years old. In this paper, we analyzed eight non-metric features and seven metric traits of this cranium. The non-metric features include sagittal keeling, mastoid process, supra-porion crest, external occipital crest, external occipital protuberance, superior nucha line, occipital torus and occipital muscular. In a comparison of these features between the Jingchuan skull cap, other human fossils and modern Chinese, we find that the Jingchuan cranium is possibly male.
