The story in short
In 1932, C. W. Gilmore published the name Polyodontosaurus. The name means “many-toothed lizard.”
Fossils referred to Polyodontosaurus 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 a carnivore and walked on two legs.
The fossils of Polyodontosaurus 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 Troodontidae, among the theropod dinosaurs.
