Torvosaurus tanneri is a species of theropod dinosaur from the Late Jurassic Morrison Formation of North America. It is known from the Carnegie Quarry at Dinosaur National Monument from a single bone, the humerus. This upper arm bone is more robust and straighter than its more common contemporary, Allosaurus. Torvosaurus was likely the largest theropod in the Morrison Formation.
