The story in short
The genus Hypsirhophus dates to 1878, the year E. D. Cope described it. The name means “high roof.”
Fossils referred to Hypsirhophus date to the Late Jurassic · Early Cretaceous (Oxfordian–Berriasian), roughly 161.5 to 137.1 million years ago. Finds come from the United States, including the Morrison Formation. It was a herbivore and walked on four legs.
The fossils of Hypsirhophus 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 Stegosauria, among the plated dinosaurs.
