Who would have guessed, the Gastonia is a herbivore and wouldn't hurt a fly, even though it looks fearsome with the large spines on its back and long tail. This dinosaur, which belongs to the avian dinosaur family (that means bird-like), only pretends to be dangerous. Instead of getting into trouble, it prefers to wander through the countryside on its sturdy legs. It's probably out looking for a lush meadow.
