Daxiatitan

Daxiatitan is a genus of titanosauriform dinosaur from the Lower Cretaceous of Lanzhou Basin, Gansu Province, northwestern China. It is known from fossils including several neck vertebrae, a shoulder blade, and a thigh bone.[1]

It was a very large dinosaur. A mounted cast of the skeleton was measured at 21 meters (69 feet) long when completed.[2] Like both Euhelopus and Huanghetitan, it had an enormously long neck.
