10. Deinonychus
As far as small-but-scary predators go, the petite theropod Deinonychus is one to look out for. In all likelihood a feathered dinosaur like Archaeopteryx, Deinonychus had formidable 5-inch talons on its feet, which it would have used to grab prey. The animal probably weighed about 150 pounds, according to Britannica, but that didn’t stop this raptor from being absolutely terrifying. I’ve included it here as a great example of a small predator being just as scary as the big ones, which tend to get more fanfare.
