Yes, They Call It "Thunder Thighs"

A newly described dinosaur from Utah had a huge hipbone that must have supported massive muscles. Why did Brontomerus ("Thunder Thighs") have such beefy limbs? One possibility, suggested by paleontologists at University College London and elsewhere and depicted by artist Francisco Gascó, is that the big muscles gave Brontomerus a formidable kick that enabled it to fight off predators (Utahraptor in the illustration).
