Polacanthus is a Ankylosaur from Western Europe. There is no full skeleton of this dinosaur but scientisis think it may resemble the dinosaur Gastonia. It was covered in bony armour and spikes. It would spend most of its days eating low vegitation in the Cretaceous jungles of Western Europe. Its main defences is its spikey tail where it can swing at predators that might think of it as a snack.
