Austria -3 Euro, Ankylosaurus, 2020

Given just how tough the armoured ankylosaurus magniventris was, it is not surprising that this massive herbivore was one of the last large non-avian dinosaurs to roam the earth. Looking like a four-legged tank with a broad torso covered in humps, spines and protected by a bone-plated corset, not to mention horns pointing backwards from the back of its head, ankylosaurus magniventris is brought to life in vivid detail on the fourth coloured coin in the Supersaurs series. Only appearing a couple of million years before the extinction of non-flying dinosaurs, at the end of the cretaceous period some 68–66 million years ago, ankylosaurus magniventris measured 9 metres in length and weighed around 3.5 tons.
