Near the end of the last ice age, a group of hunters in Washington State bagged a mastodon. A new Texas A&M University-led study of a mastodon rib—with a projectile point still embedded in it—shows that the animal lived 13,800 years ago. It’s some of the oldest evidence of hunting in the New World, and more evidence that humans arrived well before the Clovis people, once thought to be the first Americans.
