A rare, high-shouldered Morrison Formation sauropod named from a partial Colorado skeleton with a huge humerus, deep trunk vertebrae and forelimbs longer than its hind limbs.

A giant armoured titanosaur from the final few million years of the Cretaceous, widespread across the southwestern United States.
