Apatosaurus had a long, whiplike tail, stout legs, and a long neck. It was herbivorous and dwelled on land, possibly in forests, using its long neck to feed from trees. The eyes and nostrils were located toward the top of the skull. It flourished in the late Jurassic period. Apatosaurus bones and those of other sauropods have long been excavated in the Morrison formation of the late Jurassic and early Cretaceous strata in Colorado, Wyoming, and other Western states. No satisfactory skull specimen has been discovered attached to an Apatosaurus, and for many years an incorrect Camarasaurus -like head was mounted on the famous skeleton on display at the American Museum of Natural History in New York City. Apatosaurus is related to Diplodicus and Barosaurus.
