Camarasaurus lewisi

† Camarasaurus lewisi was a Late Jurassic sauropod from the Morrison Formation of Utah and Colorado, United States. Known from the nearly complete specimen 'Baby Bumpus,' it was initially thought to be a juvenile but is now considered a distinct, smaller-bodied species of Camarasaurus. Named after collector Lester F. Lewis, it was a quadrupedal herbivore with the characteristic deep skull and robust teeth of the genus, and may represent the most basal Camarasaurus species.
