This Jinniushan Man skull stands 12.3 cm high. Other fossilized remains of Jinniushan Man unearthed at the same site included vertebrae, ribs, ulnas, wrist bones, finger bones, palm bones, kneecaps, tarsal bones and metatarsal bones, all belonging to one young male. These fossils provided new material for studying the posture, gait and division of labor between hands and feet of primitive humans. Discovered in the same geological stratum were fossils of over 20 other animals, including the brown bear, the Zhoukoudian wolf (Canis variabilis), the thick-jawed deer and the rhinoceros. Stone tools and traces of human use of fire were also discovered, suggesting that Jinniushan Man, like Peking Man, lived by hunting and gathering.
