context_page_description: Gastonia is a genus of herbivorous ankylosaurian dinosaur from the Early Cretaceous of North America, around 125 million years ago. It is often considered a nodosaurid closely related to Polacanthus. Gastonia has a sacral shield and large shoulder spikes.
context_section_description: Kirkland in 1998 placed Gastonia in the Ankylosauridae, more precisely the Polacanthinae. Later, polacanthines were often seen as Nodosauridae. However, in 2014 an analysis by Victoria Megan Arbour recovered Gastonia as a non-polacanthine basal member of the Ankylosauridae.
