http://news.nationalgeographic.com/news/2009/08/090811-t-rex-dinosaurs-bully.htmlA mighty hunter has fallen—at least in the eyes of countless kids who admire the fearsome Tyrannosaurus rex.Contrary to depictions in films, in books, and with plastic toys on the living room rug, T. rex and its large predatory kin very rarely attacked full-grown adult dinosaurs, a new study says.Instead the famed carnivore was most likely a dinosaur bully, picking off defenseless youngsters."Several aspects of the supposed lifestyle of these animals didn't fit with what we knew about the behavior of modern predators," noted study co-author David Hone of the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing, China."The titanic fights often depicted were in conflict with the normal style of predation in large predatory mammals, such as lions and tigers, which usually go for the weak and inexperienced."
