The carved bone, which depicts a walking mammoth, was found near Vero Beach in east-central Florida in 2006 or 2007. (See a map of the region.) Since its discovery, scientists have been working to determine the authenticity of the 13,000-year-old artifact. Now, several experiments reveal the etching is indeed ancient, scientists reported recently in the Journal of Archaeological Science.

“This is an incredibly exciting discovery,” study co-author Dennis Stanford, an anthropologist at the Smithsonian’s National Museum of Natural History, said in a statement.
“There are hundreds of depictions of proboscideans [the order of animals with trunks] on cave walls and carved into bones in Europe, but none from America—until now.”

Oldest American Art the Real Deal

When preliminary forensic tests on the bone began in 2009, experts went on the assumption that the carving was fake.

But these tests, and further analyses by the Smithsonian team, proved that the etching was real.

The team compared elements in the engraved bones with others from the site, which once hosted giant beasts and nomadic bands of Ice Age hunters.
The scientists also observed the etching via optical and electron microscopy, which revealed “no discontinuity in coloration between the carved grooves and the surrounding material,” according to a statement. This suggests that both surfaces aged at the same time, and that the grooves were not made more recently with metal tools.

Scientists also determined the 15-inch-long (38-centimeter-long) bone fragment had belonged to one of three animals: a mammoth, a mastodon, or a giant sloth—all of which died out in the region at the end of the last ice age, between about 12,000 to 10,000 years ago.

In 2009, discoverer and local fossil hunter James Kennedy noticed the image only after dusting off the bone, which had sat under his sink for a few years.
“I had no idea it was this big of a fuss. [When I heard] there was nothing else like it in the Western Hemisphere, that’s when my heart kind of stopped.”
This is the first glimpse of real art in the Western Hemisphere.

Art and anthropology buffs can see a cast of the carved bone, now part of an exhibit at the Florida Museum of Natural History in Gainesville.
