Thyreophora is the suborder of dinosaurs (order: Ornithischia) that includes Stegosaurus and Anklyosaurus. Its name comes from the Greek meaning "shield bearing", and that pretty much describes the group's chief characteristics: bony armor from head to tail ensured maximum protection and defense for the group. They existed primarily during the Jurassic and Cretacious periods.

Despite their warlike look and spiky countenances, members of the Thereophora clade were herbivorous. They generally had low centers of gravity (relatively speaking) and walked on four legs. They exhibited herdlike tendencies, and are generally seen as ancestors of the modern ungulates such as the cow and pig. They are also a sister group to the Cerapods, the group including Hadrosaurs and Triceratops.
