"This is an exciting development," says Mark Weiss, program director of physical anthropology at NSF.

"Not only are we gaining insights into the anatomy of what may be some of our earliest ancestors, but we are seeing a better picture of the environment in which they lived.

Gai and Wei (1974) suggested an Early Pleistocene age more or less equivalent to 1 Ma for the SSZ Paleolithic site based on its Oldowan-like technology.

Further excavation in 1975 yielded three blade-like tools, which were made from good quality flints.

This provides new evidence for hominid occupation in North China in the earliest Pleistocene.

The earliest hominids are argued to have lived in a habitat of open grasslands mixed with patches of forests close to the bank of the Nihewan paleolake as indicated from faunal compositions.

The artifact layer is suggested to be located in the Matuyama reversed polarity chron just above the upper boundary of the Olduvai polarity subchron, yielding an estimated age of ca 1.7–1.6 Ma.

The discovery of this bone is the earliest evidence of a modern ...

The Nihewan Basin in North China has a rich source of Early Pleistocene Paleolithic sites.

Yohannes Haile-Selaissie, a paleontologist at the University of California at Berkeley, made the recent fossil discoveries from these earliest creatures.
