Edmontonia longiceps is at least as large as Panoplosaurus mirus (length approximately 6-7 m). It is characterized by a relatively long, narrow skull with a quadrate more oblique than in Panoplosaurus mirus. The premaxillarly palate is longer than wide. as in Panoplosaurus mirus the atlas and axis vertebrae are coossified (Sternberg, 1928).
The skull of Edmontonia rugosidens is pyriform in dorsal view, the premaxillarly palate is wider than long, and the atlas and axis are coossified (Gilmore, 1930). Edmontonia (\\\\\\\"of Edmonton\\\\\\\") was one of the largest and latest of the nodosaurids -armoured dinosaurs without the broad \\\\\\\"horns\\\\\\\", contorted nasal passages, and bony tail club of their relatives the ankylosaurids. 4 specimens including complete skulls, much of the skeleton and armor.
