High-speed camera images of force-test of Clovis-pointed spear (IMAGE)
Caption
A high-speed photo sequence during a test after an 11.34 kg weight was dropped from 35 cm shows various moments as the stone point recedes into and splinters the pike shaft. Researchers said the way the stone point could have pierced animal flesh and the wood-and-bone shaft opened up suggests that the spear as a system functioned similar to a hollow-point bullet.
