Gobititan is a genus of sauropod dinosaurs from the Titanosauria group thatlivedin what is now China during the Lower Cretaceous ( Albium ).

So far, only one find is known, which consists of the connected series of 41 middle and rear caudal vertebrae and the left hind leg. The find comes from the Mazongshan area in the northwest of the Chinese province of Gansu, which is known for its wealth of fossils . Gobititan is considered a basic (original) representative of the Titanosauria. Gobititan was scientifically described in 2003 with the only species Gobititan shenzhouensis .

Gobititan is already the third very basal representative of the Titanosauria that was described from Asia - the descriptors interpret this as an indication that the origin of the Titanosauria group could be in Asia.

features

Gobititan can be distinguished from other titanosaurs based on features of the caudal vertebrae. The proximal (on the front) articular surfaces of the middle caudal vertebrae were higher than the distal (on the back). The vertebral arches were placed relatively far back on the anterior of the posterior caudal vertebrae. The rearmost caudal vertebrae were relatively short. Compared to advanced titanosaurs, gobititan exhibited a relatively high number of caudal vertebrae - a basic feature. In advanced titanosaurs, the number of tail vertebrae was reduced to fewer than 35.

Research history and naming

The only known find was recovered from the middle classes of the Xinminbao group in the summer of 1999 . The scientific description of the new species and genus followed in 2003. The name Gobititan refers to the Gobi region and the titans of Greek mythology , which alludes to the large body size. The second part of the species name, shenzhouensis , is derived from Shenzhou, an ancient name for China.
