Edmontonia is named for the rock formation where this genus of dinosaur was first found near Edmonton, Alberta in Canada. This member of the nodosaur family (“knob lizard”) is part of the larger ankylosaur (“stiff joint lizard”) group of dinosaurs that were known for their armor and spikes.
Identification level: Genus
Edmontonia was a genus within the family Nodosauridae within the suborder Ankylosauria. An Edmontonia skull was discovered in the Talkeetna Mountains just south of Denali and is an example of an ankylosaur that may have made the tracks in the park.
What is for dinner?
Small ridged cheek teeth suggest that ankylosaurs browsed on low-growing plants like ferns and cycads. Since they lacked grinding teeth, it is probable that they swallowed their food into a digestive system that used fermentation. As with modern-day cows, this process likely resulted in large amounts of gas.
How do we know I lived in Denali?
A handful of tracks have been found in Denali that were likely made by an ankylosaur.
Some ankylosaurs had complex nasal passages. Do you think this helped them to make noises to communicate? Imagine the sounds made during the hustle and bustle of dinosaur “rush hour”.
