The Lantian people are older. The Lantian people are about 800,000-750,000 years old, and the Beijing people are about 700,000 to 200,000 years old. Lantian people are early Paleolithic humans and belong to Homo erectus. It was found in Gongwangling and Chenjiawo in Lantian County, Shaanxi. The Lantian human fossils of Gongwangling have skulls, nasal bones, right maxillas, and three molars, all belonging to an adult, possibly female. The skull is low and flat, the forehead is significantly tilted, the brow spine is thick, the bone wall is thick, the brain volume is small, estimated at 780 ml, and the snout protrudes forward, showing a more primitive form. Stone tools such as large sharpeners, choppers, scrapers and stone balls have been found in the layers of the Lantian man fossils. The processing method is a simple hammering method, and the stone chips are generally used without the second step of processing.
There are forty-one symbiotic fauna, including giant pandas, eastern saber-toothed elephants, and hairy-crested deer, with strong southern fauna colors. Chen Jiawo's Lantian man fossil has a mandible and belongs to an elderly woman. The Lantian people of Gongwangling are about 800,000-750,000 years old, and the Lantian people of Chenjiawo are about 530,000 years old. Between 800,000 and 750,000 years ago, some primitive humans lived in the Gongwangling area of present-day Lantian County, Shaanxi Province. On their low, flat foreheads, there was a noticeable bulge of thick brow bones. The stone tools they made were relatively simple, thick and large, but a closer look revealed that there were already signs of different types of stone tools. This is the famous Lantian people. Their fossils were found in the early Pleistocene strata of Gongwangling in Lantian County, Shaanxi Province, between 1963 and 1965. Archaeologists have shown that the Brain Capacity of lantian people is smaller than that of later Beijingers, about 778 milliliters. But one thing that has caught the eye is that they have been able to walk completely upright, and this is the earliest Homo erectus in northern Asia that has been discovered. The significance of this discovery is very significant, because standing upright is an important sign of becoming a person. The study of the age of the Peking Man Site has a development process. Originally, Anderson and Shidansky thought it was the Pliocene.
By the end of the 1920s, french paleontologist De Rijin (1881-1955) and Chinese vertebrate zoologist Yang Zhongjian, etc., based on the nature of the fauna, determined that the site belonged to the Middle Pleistocene, which was later than the Nihe Bay Period and earlier than the Loess Period. After the discovery of the Lantian man site in the 1960s, some people proposed to divide the Central Pleistocene in North China into early and late stages, the early ones were represented by the Lantian man site containing the Gongwangling fauna, and the late Beijing man site with the Zhoukoudian fauna was represented (see Chinese Paleolithic Archaeology). After 1976, the dating of the Peking man site was determined by various methods such as uranium system method, fission trail method, and paleomagnetic method, and it was learned that the 13th layer above was about 700,000 to 200,000 years old, and the 14th layer was earlier than 700,000 years ago.
