"With a few exceptions such as the Schöningen spears and the recent finds of wooden tools at Pogetti Vecchi, almost all of our knowledge about the Middle Paleolithic comes from durable materials (bones and stone tools)."

World's Oldest Spears

"Radiocarbon dating has confirmed that three wooden spears found in a coal mine in Schöningen, near Hannover, Germany, are the oldest complete hunting weapons ever found. Some 380,000 to 400,000 years old, the six- to 7.5-foot javelins were found in soil whose acids had been neutralized by a high concentration of chalk near the coal pit."

It should be pointed out that the radiocarbon limit is about 50K years, and that either the RC level was zero and another method was used, or a radiometric method other than RC dating was used.
