The story in short
The genus Asiatosaurus dates to 1924, the year H. F. Osborn described it. The name means “asian lizard.”
Fossils referred to Asiatosaurus date to the Early Cretaceous (Aptian · Albian), roughly 121.4 to 100.5 million years ago. Finds come from Mongolia, including the Öösh Formation. It was a herbivore and walked on four legs.
The fossils of Asiatosaurus are too incomplete for a responsible length, hip height, or weight, so those fields are left blank on purpose.
On the family tree it sits in Sauropoda, among the sauropod dinosaurs.
