Chinese paleontologists dug up a new birdlike dinosaur. Weighing in at 1.5 tons, the feathered fiend was 11 feet tall – high enough to look a T-Rex in the eye. A fringe of feathers ran down its arms toward talon-tipped paws. Its long legs were ideal for sprinting through the forests of ancient Inner Mongolia. And after pouncing, its powerful beak could shred the flesh of its prey.

Its name sounds like something out of a horror flick : Giganto-raptor! The 70-million-year-old beastie was 35 times heavier than even its largest dino/bird cousins, which top out at about 90 pounds.

And here’s the real kicker – the fossils they found were from an adolescent. “It had not reached its full size,” says Xing Xu, the research team’s leader. “It had some growing to do, and full sized Gigantoraptor would have been considerably heavier.”

A cool side note: this is the 25th new dinosaur that Xu has discovered.
