At 6m long, the edmontonia was one of the largest and last armoured dinosaurs to ever walk the earth. Its huge size meant it had strong legs to help support its weight and was also covered in sharp horns for protection against predators and as a weapon during fights. The only section of this species not covered in heavy armour was its underbelly.
The first edmontonia fossil was discovered by George Paterson in 1924 near Red Deer River in Canada. Scientists know more about this armoured dinosaur than any other due to the condition of the skeletons found.
As a plant-eater, it’s thought they use the sharp point at the end of their nose to cut through vegetation. The edmontonia existed around 67–65 million years ago, during the Late Cretaceous Period and is believed to have lived in forests and floodplains across North America and Canada.
