Ancient Siberians may have rarely hunted mammoths

Study suggests Stone Age folk sporadically killed the beasts, primarily for ivory

Contrary to their hunting reputation, Stone Age Siberians killed mammoths only every few years when they needed tusks for toolmaking, a new study finds.

People living between roughly 33,500 and 31,500 years ago hunted the animals mainly for ivory, say paleontologist Pavel Nikolskiy and archaeologist Vladimir Pitulko of the Russian Academy of Sciences. Hunting could not have driven mammoths to extinction, the researchers report June 5 in the Journal of Archaeological Science.

On frigid tundra with few trees, mammoth tusks substituted for wood as a raw material for tools, they propose. Siberian people ate mammoth meat after hunts, but food was not their primary goal.

Several European and North American sites have yielded single mammoth carcasses lying amid stone tools. Such finds could reflect either hunting or scavenging. Finds at Siberia’s Yana archeological site provide an unprecedented window on the hunting and killing of mammoths over a long time period, says archaeologist John Hoffecker of the University of Colorado Boulder.
