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.
Total known weight found, the "total known mass" could, in principle, rise. However, this is complicated by the method by which meteorites are named. Historically (before the 1970s), every meteorite was given a simple geographical name. The total number of known meteorites was small and it was generally a simple matter to determine when a newly found fragment was "paired" to a previously discovered meteorite. When pairing could be established, the new fragment would not be given a new name, and the "total known mass" of the original meteorite would increase. But, recent discoveries of arid regions containing large concentrations of meteorites have
