Two Alberta scientists have discovered Hesperonychus, a new species of velociraptor the size of a small chicken, reports the Edmonton Journal. It's the smallest dinosaur ever. Judging by its long claws, the researchers believe it probably lived, and hunted, in trees. Paleontologists originally excavated the dinosaur in 1982, but because it was so small, it took more than 25 years to get around to taking a close look at it.
