This specimen of ankylosaurian dinosaur was originally published by F. A. Lucas as Stegosaurus marshi. It was subsequently transferred to a new genus by Lucas in 1902, where it was recognized as distinct from typical stegosaurs. In 1994, J. Pereda-Suberbiola proposed that Hoplitosaurus is the same dinosaur as the earlier-named Polacanthus. It is not known whether this specimen represents a single individual.
