Euhelopus is a genus of sauropod dinosaur that lived between 145 and 133 million years ago during the Berriasian and Valanginian stages of the Early Cretaceous[1] in what is now Shandong Province in China. It was a large quadrupedal herbivore. Like sauropods such as brachiosaurs and titanosaurs, 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 and studied by T'an during the same year.[2] Unlike most sauropod specimens, it has a relatively complete skull.[3]
Euhelopus was a long-necked sauropod similar to Mamenchisaurus, but its affinities are controversial. Most studies favor a close relationship between Euhelopus and titanosaurs, rather than mamenchisaurids.
