Gastonia is a Ankylosaur from North America that lived during the early crettaceous period. It was covered in a bony armour with several patruding spikes on its back, with a whip like tail. It lived a solitary life only to mate with what ever of its kind is around. They where mainly herbivores and ate the low lying plants. At this time most of North America's top carnivores like Tyrannosaurus Rex has not evolved yet. But this Ankylosaur had to match with the dromeosaur known as Utahraptor. It was a slow walker, but it does not have to worry because it is designed to be as defensive as a tank.
