Today, it is generally agreed that their spiked tails were most likely used for defense against predators, while their plates may have been used primarily for display, and secondarily for thermoregulatory functions.

Description
Stegosaurus tail spike and spine plate replicas measure 14.0″L x 8.0″W, Spike measures 20.0″L. Both replicas are museum-quality polyurethane resin castings of original specimens from Cleveland-Lloyd Dinosaur Quarry. Made in USA.
Stegosaurus or Stegosaurus stenops were large, heavily built, herbivorous quadrupeds with rounded backs, short fore limbs, long hind limbs, and tails held high in the air.
Due to their distinctive combination of broad, upright plates and tail tipped with spikes, stegosaurus is one of the most recognizable kinds of dinosaurs. The function of this array of plates and spikes has been the subject of much speculation among scientists.
Today, it is generally agreed that their spiked tails were most likely used for defense against predators, while their plates may have been used primarily for display, and secondarily for thermoregulatory functions. Stegosaurus had a relatively low brain to body mass ratio. It had a short neck and a small head, meaning it most likely ate low-lying bushes and shrubs.
The long and narrow skull was small in proportion to the body. Stegosaurus had a small antorbital fenestra, the hole between the nose and eye common to most archosaurs, including modern birds, though lost in extant crocodylians.
The skull’s low position suggests that stegosaurus may have been a browser of low-growing vegetation. This interpretation is supported by the absence of front teeth and their likely replacement by a horny beak or rhamphotheca.
The stegosaurus lower jaw had flat downward and upward extensions that would have completely hidden the teeth when viewed from the side, and these probably supported a turtle like beak in life. The presence of a beak extended along much of the jaws may have precluded the presence of cheeks in these species.
