Euhelopus
''Euhelopus'' is a genus of titanosauriform sauropod dinosaur that lived between 129 and 113 million years ago during the Early Cretaceous in what is now Shandong Province in China. It was a large quadrupedal herbivore, it weighed approximately 15-20 tons and attained an adult length of 〔 Unlike most other sauropods, ''Euhelopus'' had longer forelegs than hind legs. This discovery was paleontologically significant because it represented the first dinosaur described from China: seen in 1913, rediscovered in 1922, and excavated in 1923.〔H. C. T'an. 1923. New research on the Mesozoic and early Tertiary geology in Shantung. Geological Survey of China Bulletin 5:95-135〕 Unlike most sauropod specimens, it has a relatively complete skull. ==Discovery and naming== It was originally named ''Helopus'', meaning "Marsh Foot" by Carl Wiman in 1929, but this name already belonged to a bird. It was renamed ''Euhelopus'' (Good marsh-foot) in 1956 by Romer. There is a plant genus (a grass) with the same generic name. However, a genus in one biological kingdom may have a name that is used as a genus name in another kingdom, so ''Euhelopus'' was allowed.
