Abstract: A human maxilla associated with fossil mammals has been discovered during the 1983 excavation season at the site which yielded an occipital bone in 1982. The maxilla, though not complete, shows characters of early Homo sapiens Based on faunal dating, the geological age of the human fossils is equal to or somewhat later than that of the layers I-4 of Zhoukoudian Cave, as suggested by fossil materials from the ame site in 1982.
