北京猿人遗址位于北京西南约四十八公里的周口店镇西部龙骨山。自1921年以来,特别是解放以后,经过多次挖掘,在这里找到了丰富的古人类化石和哺乳动物化石。根据伴生动物群的对比和古人类化石特征,我国科学家曾估计北京猿人生存在四、五十万年以前,但未进行同位素年龄测定。 在北京猿人遗址发现了大量用火遗迹。猿人洞有多层灰烬,有的厚达6米。灰烬里有烧 Peking Man Site is located in Longkou Mountain, western part of Zhoukoudian, about 48 kilometers southwest of Beijing. Since 1921, especially after the liberation, after excavations many times, rich ancient fossils and mammal fossils have been found here.

In Peking Man Site found a large number of fire relics. Ape hole many layers of ashes, and some as thick as 6 meters. Burning in the ashes
