Paleontologists at the University of Alberta
have found evidence that a feathered, but flightless raptor-like dinosaur preyed on ancient birds. Three fossils of Confuciusornis sanctus,
a primitive bird-like creature, were found in the fossilized abdomens of a pair of Sinocalliopteryx gigas -- a relative of T-Rex that was about the size of a large wolf
. It's the first time a predatory dinosaur has been found dining on avian fare, and a reminder that while battles between titans like allosaurus and stegosaurus may dominate our imaginations, the majority of dinosaur-on-dinosaur violence probably looked familiar
to anyone who has watched a modern predator stalk prey in a nature documentary. Except it would be with dinosaurs, and thus a billion times cooler.
