  • Euhelopus zdanskyi

Euhelopus ( "good mud-feet" ) was a sauropod dinosaur , which wasdiscovered and describedby Carl Wiman in1929 in the Meng-Yin Formation in the Chinese province of Shandong . It lived in the Lower Cretaceous about 130 to 112 million years ago and could reach a length of about 15 meters. The weight was estimated to be more than 15 tons. Regarding the system , Euhelopus is counted amongthe Titanosauria . This group is mainly represented by massive sauropods. So faronly one species of this genus is known, Euhelopus zdanskyi . The front extremities, which are longer than the rear ones, arespecial on the physique of Euhelopus . Otherwise, its appearance resembles that of other sauropods, so it had a long neck and tail, a massive body supported by four sturdy legs, and a small skull. Euhelopus was herbivorous (fed on plants).

Originally this dinosaur was named Helopus by Wiman . However, a bird already had this name. Accordingly, in 1956 the name Helopus was changed from Alfred Romer to Euhelopus . There is also a species of plant called Helopus , but this is only possible because plants and birds are in two different realms .

So far no complete skeleton of Euhelopus has been recovered. For the most part, fragments of cervical vertebrae and the spine and a toothless skull have been discovered. These fossil finds are now in the Paleontological Museum of Uppsala University , Sweden .
