Scientists think this bone fragment with the carved image of a mammoth or mastodon is at least 13,000 years old.
While prehistoric art depicting animals with trunks has been found in Europe, this may be the first in the Western Hemisphere, researchers have reported in the Journal of Archaeological Science.
"It's pretty exciting, we haven't found anything like this in North America," said report co-author Dennis J. Stanford, curator of North American Archaeology at the Smithsonian's National Museum of Natural History.
They hunted these animals, Stanford explained, and "you see people drawing all kinds of pictures that are of relevance and importance to them."
"Much of the significance of such finds is in the tangible, emotional connection they allow us to feel with people in the deep past," said Emory University anthropologist Dietrich Stout.
