First appearance: "Raptor's Last Stand" (only appearance)

Gastonia is a genus of nodosaurid dinosaur from the Early Cretaceous of North America, around [147-127] Closely related to Polacanthus, it has a sacral shield and large shoulder spikes. It is also the first polacanthine dinosaur to have been mounted for display at the Denver Museum of Nature and Science, together with the related Gargoyleosaurus. This dinosaur was found in the same quarry as Utahraptor, the largest known dromaeosaurid.

Gastonia made its first appearance in "Raptor's Last Stand", where it fought a Utahraptor during a drought.


This tank-like ankylosaurid dinosaur stood 5 feet tall, measured 5 meters (16.5 feet) long and weighed about 2 tons. It walked on four short stocky legs and its entire body was covered by bony plates and spikes of different sizes and shapes. Gastonia was also the spiniest of all ankylosaurs.

Fighting StyleEdit

Because of all its heavy armor, Gastonia was slow-moving with poor eyesight but a powerful sense of smell and hearing. while the solid bony plate over its hips allowed it to crouch and protect its vulnerable abdominal zone from attacking predators, it used the spikes all over its body and particularly on its tail as offensive weapons. The sharp bony triangular plates near the base of Gastonia's tail acted like powerful, sharp shears, seriously wounding a predator unlucky enough to get caught in its path.


  • Gastonia was named for the paleontologist Robert Gaston, who made the first discovery of its fossilized remains in Moab, Utah, in 1989.
