Paleontologists have long known that dinosaurs had tiny brains, but they had no idea the beasts were such airheads. Scientists suggest that newly discovered large air spaces helped lighten the load of the head, making it about 18 percent lighter than it would have been without all the air. That savings in weight could have allowed the predators to put on more bone-crushing muscle or even to take larger prey.
