The story in short

The genus Jiutaisaurus dates to 2006, the year W. H. Wu and colleagues described it. The name honors a person tied to the fossil or its study.

It lived in the Early Cretaceous (Aptian · Albian), roughly 121.4 to 100.5 million years ago. Finds come from China, including the Quantou Formation. It was a herbivore and walked on four legs.

The fossils of Jiutaisaurus 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 Titanosauriformes, among the sauropod dinosaurs.
