Field notes

About Gastonia

What it was like

Gastonia was an armored plant eater about 4.6 meters (15 feet) long. Its back was covered in bony plates, large spikes stuck out from its shoulders and sides, and a solid shield of fused armor covered its hips.

It had a low, wide body and walked on four short legs. Its closest relative was probably Polacanthus from England.

Its world

It lived in the Early Cretaceous, in what is now Utah. Its fossils come from the Cedar Mountain Formation, where the big raptor Utahraptor also lived and may have been among its dangers.

Other neighbors included the plant eater Falcarius and the armored Peloroplites.

How it was found

Kirkland named Gastonia in 1998. Three finds are known, and its bones were found in the same quarry as Utahraptor.
