Jinchuanloong is a relatively basal sauropod that measured an estimated 10 m in length. Sauropod skulls typically don't preserve well in the fossil record, but Jinchuanloong is known mainly from the skull, and parts of the neck and tail. Like all sauropods, Jinchuanloong was a quadrupedal herbivore that used its long neck to reach the vegetation that it fed on.
