a herbivorous polacanthid ankylosaurian dinosaur from the Early Cretaceous of North America.
for Robert Gaston
James Kirkland (1998
(for Gaston and Burge)Etymology
is named in honor of Robert Gaston, discoverer of the fossil site.
The species epithet
(BUHR-jie), honors Donald L. Burge, director of the College of Eastern Utah Prehistoric Museum.
The first remains of Gastonia
were discovered at "Gaston Quarry" in the Yellow Cat Member of the Cedar Mountain Formation, Grand County, Utah, by Robert Gaston in 1999. The holotype
(CEUM 1307) is an adult skull, 295mm long and 283 mm wide.
Many hundreds of disarticulated bones and pieces of armour, from perhaps ten individuals of different growth stages, have been discovered at Gaston Quarry and the Dalton Wells Dinosaur Quarry combined, which makes Gastonia
the best-represented basal ankylosaur by far. The former site also yielded the remains of an as-yet unnamed iguanodontid and the holotype of Utahraptor
