Mammoth image carved into bone authenticated

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.[tweetmeme][Full story] Story: Christine Dell'Amore, National Geographic News | Photo: Chip Clark, Smithsonian Institute
