The story in short
Stephanosaurus was formally named in 1914 by L. M. Lambe.
It lived in the Late Cretaceous (Campanian), roughly 83.6 to 72.2 million years ago. Finds come from Canada. It was a herbivore. A habitual gait is not settled.
The fossils of Stephanosaurus 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.
