Edmontonia (Lat. Edmontonia) - the genus of the shelter dinosaurs, which belongs to the family of the Nodozavride, from the late chalk. The skeletons of Edmontonia were found on the territory of Canada and the United States.
The lizard is named after the Edmonton geological formation, which is located in the Canadian province of Albert, where his remains were found for the first time
Edmontium was a herbivore dinosaur weighing about 4 tons with a height of 2 meters and a length of 7 meters [2]. Its back and the top of the head were covered with bone plates that closer to the tail became more like spikes.
The four of the largest spikes were left from the shrug of the lizard in different directions, serving as protection or tools for the struggle between relatives
A typical view of the lizard (E. Longiceps) was first discovered in 1924 by George Panson in the geological formation of Horsehoe Canyon near the village of Morrin. However, the name was given to him only in 1928 by Charles Sternberg. Holotype NMC 8531 consists of a partial skeleton.
Later in the geological formation of Aguya in Texas, another species was found, which in 1930 was named E. Rugosidens. Due to differences in the structure of the skull with a typical view, Robert Beckker treated him to a separate family or the ratio of Chassternbergia (in honor of Sternberg), which, however, does not find general recognition in the scientific environment
The third known view is E. Australis, which is known only on the found cervical panels [6], is currently synonymous with Glyptodontopelta (Burns, 2008)
