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. Unlike most other sauropods, Euhelopus had longer forelegs than hind legs. This discovery was paleontologically significant because it represented the first dinosaur scientifically investigated from China: seen in 1913, rediscovered in 1922, and excavated in 1923. Unlike most sauropod specimens, it has a relatively complete skull.
