If dinosaur evolution were an Austin Powers movie, T. rex would be Dr. Evil. And today scientists unveiled Mini-Me. But in this case, it was the tiny terror that gave rise to the larger, more infamous relation. Raptorex kriegsteini likely lived about 125 million years ago, during the Cretaceous period.
