Dystylosaurus was a giant plant-eater that was probably very similar to Brachiosaurus  It is known from one very large back bone. Although this one bone can't tell us exactly what it looked like, if it was like a brachiosaur it would have been more than 70 feet (21 m) long and weighed more than 30 tons (27,000 kilos). Like Brachiosaurus  it would have had front legs longer than its back legs and its head would have been held high off the ground.

Although it is thought to most certainly belong to the brachiosauridae, it is clearly different from Brachiosaurus  It is believed likely that more of this individual was collected and misidentified as the quarry in which it was discovered has yielded a number of large sauropod specimens.
