Gastonia is a genus of nodosaurid dinosaur from the Early Cretaceous of North America, around 125 million years ago.
Closely related to Polacanthus, it has a sacral shield and large shoulder spikes.
The gastonia has a shield over its pelvis and large, pointed spikes all over it's back. A small set of sidways spikes run sideways all down it's tail.This armor was used to fight off predators,such as utharaptor, which has been found in the same area.
The gastonia was one of the most protected ankylosaurs but it didn't have a tail club, so it was a nodasaur. It lived in North America during the early Cretaceous period. It probably evolved from animals like gargoylesaurus, an early Ankylosaur. It had spikes on it's back for protection.It's spikes, on its tail, can deal a lot of damge to attackers.It was liked because of its spikes.
