Sonidosaurus saihangaobiensis

After half a dozen years of prodding and poking, paleontologists came to the conclusion that Sonidosaurus was a titanosaur, but even then which branch of the titanosaurian tree was unclear because of a pesky hotch-potch of primitive and derived features.

The latest research suggest it's an antarctosaurid (previously known as titanosaurids), sisters of the saltasaurids, and together they make up Lithostrotia — "paved with stones" — which refers to their armoured backs. Funnily enough, the known remains of Sonidosaurus doesn't include an armoured back, or any kind of armour. And its back isn't the best.

Sonidosaurus is a pretty low-key sauropod and little-talked about. Even a television documentary that was being filmed to re-enact its discovery was canned because a bone, pulled at random and dusted off by Chinese paleontologist Xu Xing, turned out to belong to the huge oviraptorosaur Gigantoraptor!

The lizard from Sonid was small for a sauropod, being only a tad larger than the theropod that stole its thunder, and despite being a resident of South America it seems to have more in common with the Asian titanosaur Opisthocoelicaudia.
Etymology
Sonidosaurus is derived from "Sonid" (from Sonid Zuoqi — the large geographical area which contains the type locality) and the Greek "sauros" (lizard).
The species epithet (or specific name), saihangaobiensis, honors the actual type locality - the town of saihangaobi — 15 km southwest of Erenhot (also known as Erlian, Eriyen and Ereenor). "Ensis", in Latin, means "from".
Discovery
The remains of Sonidosaurus were discovered in the Iren Dabasu Formation by an expedition team from the Department of Land and Resources of Nei Mongol in 2001.
The holotype (LH V 0010, housed at the Long Hao Geologic and Paleontological Research Center) is a partial skeleton including five back (dorsal) vertebrae, the last hip (sacral) vertebra, one tail (caudal) vertebra, several ribs, one bone from the underside of the tail (chevron) which protects nerves and blood vessels, and a partial hip (left and right ilia, partial left pubis, and both ischia).
