About Quaesitosaurus
What it was like
Quaesitosaurus was a titanosaur, a long-necked, four-legged plant eater, known only from a partial skull. Its skull was long and low, with thin, peg-like teeth at the front of its jaws, a little like that of Diplodocus.
Its ear region suggests it had good hearing.
Its world
It lived in the Late Cretaceous in what is now Mongolia. Its skull comes from the Baruungoyot Formation, where it shared the land with the armored Saichania and Tarchia.
How it was found
Kurzanov and Bannikov named Quaesitosaurus in 1983, from a single find. It may be a close relative, or even the same animal, as Nemegtosaurus, which is also known only from a skull.
