Pachycephalosaurus is an extinct genus of pachycephalosaurid dinosaurs. It lived during the late Cretaceous period in what is now North America from 68 to 65 million years ago. It grew up to about 5 metres (16 feet) long and weighed about 370–450 kilograms, was a biped with strong hind limbs and much less developed forelimbs. It is famous for having a large, bony dome atop its skull, up to 25 cm (10 in) thick, which safely cushioned its tiny brain. The skull was short, and possessed large, rounded eye sockets that faced forward, suggesting that the animal had good eyesight and was capable of binocular vision. It probably had a fairly short, thick neck, a bulky body, long hind legs and a heavy tail, which was likely held rigid by ossified tendons and is largest known dome-skulled and bone-headed dinosaur.
