Restoration with hypothetical body

Quaesitosaurus (meaning "extraordinary lizard") is a genus of nemegtosaurid sauropod containing only the type species, Q. orientalis, described by Kurzanov and Bannikov in 1983.[1] It lived from 85 to 70 million years ago during the Late Cretaceous (Santonian to Campanian ages). Its fossils, consisting solely of a partial skull, were found in the Barun Goyot Formation near Shar Tsav, Mongolia.[1] With long, low and horse-like with frontally located peg-teeth, the skull of Quaesitosaurus is similar enough to the skull of Diplodocus and its kin to have prompted informed speculation that the missing body was formed like those of diplodocids.[2]

It is possible that Nemegtosaurus, also known from only skull material, is a very close relative of Quaesitosaurus.[2]
