The flowers are only a tenth of an inch in diameter, and they’re the first complete flowers that have ever been discovered from so long ago, according to a study released this week from Oregon State University.

He’s been forging the kinds of weapons used by the Clovis people who inhabited North American some 12,000 years ago.
