The story in short
The genus Priodontognathus dates to 1875, the year H. G. Seeley described it. The name means “saw tooth jaw.”
Fossils referred to Priodontognathus date to the Late Jurassic (Oxfordian), roughly 161.5 to 154.8 million years ago. Finds come from the United Kingdom, including the Calcareous Grit Formation. It was a herbivore and walked on four legs.
The fossils of Priodontognathus 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 Ankylosauria, among the armored dinosaurs.
