Edmontonia is one of the largest armoured dinosaurs on record.
Approximately eight complete, or nearly complete, skeletons have been found. Edmontonia was first discovered in 1924 in the dinosaur bone beds around Drumheller, Alberta, western Canada. Since then, other remains have been dug up in Montana, South Dakota and Texas.
There are several different kinds of Edmontonia. They are identified by the length of the shoulder spikes and what kind of body armour they have. The best known form is Edmontonia longiceps or 'the dinosaur with long spines from Edmonton'.
Edmontonia's head was rather box like. The beak seems to have had a rounded shape, and there were several rows of small teeth lining the edges of the jaws. The huge shoulder spikes could be used effectively as horns against a hungry predator.
Rows of bony shields across the neck and more rows of bony plates along the back and tail gave Edmontonia quite a lot of protection. Strangely, it had a very long tail.
