Brachiosaurus

Brachiosaurus is a genus of sauropod dinosaur from the Jurassic Morrison Formation of North America. Brachiosaurus had a disproportionately long neck, small skull, and large overall size, all of which are typical for sauropods. It is regarded as a high browser, probably cropping or nipping vegetation as high as possibly 9 metres (30 ft) off of the ground. The skull had a robust, wide muzzle and thick jaw bones, with spoon–shaped teeth.
