Apatosaurus the problem of supplying blood to the brain because it would not have been elevated. James Farlow (1987) calculates that an "Apatosaurus"-sized dinosaur about would have possessed of fermentation contents. Assuming "Apatosaurus" had an avian respiratory system and a reptilian resting-metabolism, Frank Paladino etal. (1997) estimate the animal would have needed to consume only about of water per day. A 1999 microscopic study of "Apatosaurus" and "Brontosaurus" bones concluded the animals grew rapidly when young and reached near-adult sizes in about 10years. In 2008, a study on the growth rates of sauropods was published by Thomas Lehman and Holly Woodward.
Apatosaurus was found a short distance from a skeleton (specimen CM3018) identified as the new species "Apatosaurus louisae", named after Louise Carnegie, wife of Andrew Carnegie, who funded field research to find complete dinosaur skeletons in the American West. The skull was designated CM11162; it was very similar to the skull of "Diplodocus". Another smaller skeleton of "A.louisae" was found nearby CM11162 and CM3018. The skull was accepted as belonging to the "Apatosaurus" specimen by Douglass and Carnegie Museum director William H. Holland, although other scientistsmost notably Osbornrejected this identification. Holland defended his view in 1914 in an address to the
