The story in short

In 2012, R. A. Coria and colleagues published the name Lapampasaurus. The name means “la Pampa lizard.”

It lived in the Late Cretaceous (Maastrichtian), roughly 72.2 to 66 million years ago. Finds come from Argentina, including the Allen Formation. It was a herbivore and could move on two or four legs.

The fossils of Lapampasaurus 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 Hadrosauridae, among the ornithopod dinosaurs.
