The story in short
In 1940, R. M. Sternberg published the name Caenagnathus. The name means “recent jaw.”
Fossils referred to Caenagnathus date to the Late Cretaceous (Campanian), roughly 83.6 to 72.2 million years ago. Finds come from Canada, including the Dinosaur Park Formation. It was an omnivore and walked on two legs.
The fossils of Caenagnathus 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 Caenagnathidae, among the theropod dinosaurs.
