is a genus
of polacanthine ankylosaurid 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. 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
Discovery and species
Named by James Kirkland
in 1998 from material recovered in Grand County Utah
, more complete material exists for Gastonia
than for any other polacanthine ankylosaur. Unfortunately, a wealth of disarticulated material from a bonebed presents problems as it can be hard to tell how many spikes a particular Gastonia
actually had. Gastonia
was named after Robert Gaston.
The type species is G. burgei.
- Gastonia is featured in an episode of Paleoworld where it is presented as the most heavily armored dinosaur.
- Gastonia is featured in a chapter of Raptor Red, Robert T. Bakker's fictional account of the events in the life of a female Utahraptor. Defense behaviors are described as an Acrocanthosaurus attacks a young Gastonia (without success). Later on, male Gastonia are shown to compete in leks, and losers wallow in shallow pools, sometimes exposing their armor-less bellies. Because of this, one is killed by a Utahraptor pack.
- Gastonia appeared in an episode of Jurassic Fight Club, where it fights a Utahraptor.
