The story in short
In 1869, E. D. Cope published the name Ornithotarsus.
It lived in the Late Cretaceous (Campanian), roughly 83.6 to 72.2 million years ago. Finds come from the United States. It was a herbivore. A habitual gait is not settled.
The fossils of Ornithotarsus 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.
