Atlantosaurus

Atlantosaurus, a name given by Professor Marsh to what appears to be the largest deinosaurian reptile of which any remains have been preserved. The femur of this colossal monster is more than 8 feet in length. The size of the bone indicates a length for the animal of nearly 100 feet, and a height of 30 feet or thereabout. The remains were obtained in the Jurassic strata of Colorado.
