Marsh had discovered the partial skeleton of an giant, long-necked dinosaur he called the Apatosaurus, affixing the skull of another dinosaur, believed to be a Camarasaurus, to complete the find. Two years later, a second, more complete Apatosaurus skeleton was found, which Marsh called the Brontosaurus.
