Euhelopus

Euhelopus is a genus of sauropod dinosaur that lived during the Early Cretaceous, sometime between 130 and 112 million years ago (Barremian or Aptian stages). It lived in what is now Shandong Province in China. A large herbivore, it weighed approximately 15-20 tons and attained an adult length of 15m (50 feet). Unlike most other sauropods, Euhelopus had longer fore legs than hind legs.

Discovery and Species
It was originally named Helopus, meaning "Marsh Foot" by Wiman in 1929, but this name already belonged to a bird. It was renamed Euhelopus in 1956 by Romer. There is a plant genus (a grass) with the same generic name. However, a genus in one biological kingdom is allowed to bear a name that is in use as a genus name in another kingdom, and the name Euhelopus has been allowed. The type species is Euhelopus zdanskyi. Euhelopus is known from a partial skeleton composed of most of the neck and spinal column and a skull that was missing its teeth. The type material is in the Paleontological Museum of Uppsala University, Uppsala, Sweden.
