Abstract: A piece of human skull and seven human teeth were excavated from the deposits in fissures of Qizian Hill, Yiyuan county, Shandong Province (E. 118°9', N.36°12') in 1981-1982.
The piece of skull consists of fragments of parietal, frontal and occipital bones, which belong to an adult individual. The skull is rather thick, 9mm. and 13mm.at the bregma and the left asterion respectively.
Two pieces of the supraorbital torus belong to the left and right on?s separately. They are very heavy. The supratoral sulcus between the torus and the frontal squama is noticeable, with supraorbital incisure. Morphologically they are comparable to Peking Man.
All seven teeth are permanent, which include one canine, four premolars and two molars. They came at least from two individuals. These teeth are similar to those of Peking Man both in size and characters.
We classify the Yiyuan fossil Man to Homo erectus. According to the fauna associated with the human fossil the geological age of Yiyuan Man can be placed in the Middle Pleistocene.
