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.
