In the past, some paleontologists, notably Robert Bakker, have speculated the plates may have been mobile to some degree, although others disagree.[ Bakker suggested that the plates were the bony cores of pointed horn-covered plates that a Stegosaurus could flip from one side to another to present a predator with an array of spikes and blades that would impede it from closing sufficiently to attack the Stegosaurus effectively. The plates would naturally sag to the sides of the Stegosaurus, the length of the plates reflecting the width of the animal at that point along its spine. His reasoning for these plates to be covered in horn is that the surface fossilized plates have a resemblance to the bony cores of horns in other animals known or thought to bear horns, and his reasoning for the plates to be defensive is that the plates had insufficient width for them to stand erect easily in such a manner as to be useful in display without continuous muscular effort.
The function of the plates has been much debated. Initially thought of as some form of armor, they appear to have been too fragile and ill-placed for defensive purposes, leaving the animal's sides unprotected. More recently, researchers have proposed that they may have helped to control the body temperature of the animal, in a similar way to the sails of the pelycosaurs Dimetrodon and Edaphosaurus (and the ears of modern elephants and jackrabbits). The plates had blood vessels running through grooves and air flowing around the plates would have cooled the blood. Recent structural comparisons of Stegosaurus plates to Alligator osteoderms seem to support the conclusion that the potential for a thermoregulatory role in the plates of Stegosaurus exists. This theory has been seriously questioned, since its closest relatives, such as Kentrosaurus, had more low surface area spikes than plates, implying that cooling was not important enough to require specialized structural formations such as plates.
--------
The spikes of Stegosaurus were most likely used for defense. The back plates have also been proposed as a defensive mechanism, as well as having display and thermoregulatory functions.
The most recognizable features of Stegosaurus are its dermal plates, which consist of 17 separate flat plates. These were highly modified osteoderms (bony-cored scales), similar to those seen in crocodiles and many lizards today. They were not directly attached to the animal's skeleton, instead arising from the skin. The largest plates were found over the animal's hips and measured 60 centimeters (2 ft) wide and 60 centimeters tall.
By the early 1960s, two rows of alternating plates had become (and remains) the prevalent idea, mainly because the one Stegosaurus stenops fossil with the plates still articulated indicates this arrangement.

Stegosaurus had a stiffened tail held high in the air. Its array of plates and spikes has been the subject of much speculation.
There has been debate about whether the tail spikes were used for display only, as posited by Gilmore in 1914 or used as a weapon. Robert Bakker noted the tail was likely to have been much more flexible than that of other dinosaurs, as it lacked ossified tendons, thus lending credence to the idea of the tail as a weapon. However, as Carpenter has noted, the plates overlap so many tail vertebrae that movement would be limited. Bakker also observed that Stegosaurus could have maneuvered its rear easily, by keeping its large hindlimbs stationary and pushing off with its very powerfully muscled but short forelimbs, allowing it to swivel deftly to deal with attack. More recently, a study of tail spikes by McWhinney et al., which showed a high incidence of trauma-related damage, lends more weight to the position that the spikes were indeed used in combat. This study showed that 9.8% of Stegosaurus specimens examined had injuries to their tail spikes. Additional support for this idea was a punctured tail vertebra of Allosaurus into which a tail spike fit perfectly.
Stegosaurus stenops had four dermal spikes, each about 60–90 centimeters (2–3 ft) long. Discoveries of articulated stegosaur armor show that, at least in some species, these spikes protruded horizontally from the tail, not vertically as is often depicted. Initially, Marsh described S. armatus as having eight spikes in its tail, unlike S. stenops. However, recent research re-examined this and concluded this species also had four.
The tail spike of Stegosaurus have been called Thagomizers after Gary Larson's "Far Side" comic strip.

Huayangosaurus taibai skull cast replica |  Huayangosaurus taibai skull cast replica pronounced: HWA-yang-oh-SORE-us Middle Jurassic Zigong, Sichuan Measures 42x20x29cm (16.535 x 7.87 x 11.41 inches ) Purchase price: $3,500
Kingdom: Animalia, Phylum: Chordata, Class: Sauropsida, Superorder: Dinosauria,
Order: Ornithischia, Suborder: Thyreophora, Infraorder: Stegosauria, Family: Huayangosauridae |  Huayangosaurus is a genus of stegosaurian dinosaur from the Middle Jurassic of China. The name derives from "Huayang", an alternate name for Sichuan (the province where it was discovered), and "saurus", meaning "lizard". It lived during the Bathonian to Callovian stages, before its famous relative, Stegosaurus appeared in North America. At only 4.5 metres long, it was also much smaller than its famous cousin. Found in the Lower Shaximiao Formation, Huayangosaurus shared the local Middle Jurassic landscape with the sauropods Shunosaurus, Datousaurus, Omeisaurus and Protognathosaurus, the ornithopod Xiaosaurus and the carnivorous Gasosaurus. As it is the most basal stegosaurian, it is placed in within its own family Huayangosauridae. It is also morphologically distinct from later (stegosaurid) forms. Its skull was broader and had premaxillary teeth in the front of its mouth. All later stegosaurians lost these teeth. Please call (314) 556-0650 or email us for more pictures or information.

The type and only species, Tuojiangosaurus multispinus, was named in 1977 (exactly a hundred years after Stegosaurus) on the strength of two specimens, one over half complete.
Like its compatriot Kentrosaurus, Tuojiangosaurus had two rows of pointed plates along the spine, which became taller over the hip region. It also had two outward-pointing spikes on each side of the end of the tail (click for picture), angled approximately at 45 degrees to the vertical. In stegosaurs, this spike arrangement has become affectionately known as the "thagomizer". It also had the typical narrow head, bulky body, and low teeth of other stegosaurids.
Because it lacked the tall spines for muscle attachment found on the vertebrae of Stegosaurus, it was probably unable to rear up on its hind legs like that animal. This suggests that it would have eaten low-lying, ground vegetation

Stegosaurus is a genus of stegosaurid armoured dinosaur from the Late Jurassic period (late Kimmeridgian to Early Tithonian) in what is now western North America. In 2006, a specimen of Stegosaurus was announced from Portugal, showing that they were present in Europe as well. Due to its distinctive tail spikes and plates, Stegosaurus is one of the most recognizable dinosaurs, along with Tyrannosaurus, Triceratops, and Apatosaurus. The name Stegosaurus means "roof-lizard" and is derived from the Greek stegos- ("roof") and -sauros ("lizard"). At least three species have been identified in the upper Morrison Formation and are known from the remains of about 80 individuals. They lived in an environment and time dominated by the giant sauropods Diplodocus, Camarasaurus, and Apatosaurus.
A large, heavily built, herbivorous quadruped, Stegosaurus had a distinctive and unusual posture, with a heavily arched back, short forelimbs, head held low to the ground and a stiffened tail held high in the air. Its array of plates and spikes has been the subject of much speculation. The spikes were most likely used for defense, while the plates have also been proposed as a defensive mechanism, as well as having display and thermoregulatory (heat control) functions. Stegosaurus was the largest of all the stegosaurians (bigger than genera such as Kentrosaurus and Huayangosaurus) and, although roughly bus-sized, it nonetheless shared many anatomical features (including the tail spines and plates) with the other stegosaurian genera.
Stegosaurus was the first-named genus of the family Stegosauridae. It is the type genus that gives its name to the family. Stegosauridae is one of two families within the infraorder Stegosauria, with the other being Huayangosauridae. Stegosauria lies within the Thyreophora, or armoured dinosaurs, a suborder which also includes the more diverse ankylosaurs. The stegosaurs were a clade of animals similar in appearance, posture and shape that mainly differed in their array of spikes and plates. Among the closest relatives to Stegosaurus are Wuerhosaurus from China and Kentrosaurus from east Africa.

Nomina dubia (dubious names):
Strata at Como BluffStegosaurus ungulatus, meaning "hoofed roof lizard", was named by Marsh in 1879, from remains recovered at Como Bluff, Wyoming.[15] It is known from a few vertebrae and armour plates. It might be a juvenile form of S. armatus,[16] although the original material of S. armatus is yet to be fully described. The specimen discovered in Portugal and dating from the upper Kimmeridgian-lower Tithonian stage has been ascribed to this species.[1]
Stegosaurus sulcatus, meaning "furrowed roof lizard" was described by Marsh in 1887 based on a partial skeleton.[13] It is considered a synonym of S. armatus.[16] Stegosaurus duplex, meaning "two plexus roof lizard" (in allusion to the greatly enlarged neural canal of the sacrum which Marsh characterized as a "posterior brain case"), is probably the same as S. armatus.[16] Although named by Marsh in 1887 (including the holotype specimen), the disarticulated bones were actually collected in 1879 by Edward Ashley at Como Bluff, Wyoming.
Stegosaurus seeleyanus, originally named Hypsirophus, is probably the same as S. armatus. Stegosaurus (Diracodon) laticeps was described by Marsh in 1881, from some jawbone fragments.[17] Just as some consider S. stenops a species of Diracodon, others consider Diracodon itself to be a species of Stegosaurus. Bakker had resurrected D. laticeps in 1986,[18] although others note that the material is non-diagnostic and likely synonymous with S. stenops.[11]
Stegosaurus affinis, described by Marsh in 1881, is only known from a pubis and is considered a nomen dubium.[16] It is possibly synonymous with S. armatus.[14]
Reassigned species
Stegosaurus madagascariensis from Madagascar is known solely from teeth and was described by Piveteau in 1926. The teeth were variously attributed to a stegosaur, the theropod Majungasaurus,[19] a hadrosaur or even a crocodylian.
Other remains originally attributed to Stegosaurus are now considered to belong to different genera. This is the case for Stegosaurus marshi, which was described by Lucas in 1901. It was renamed Hoplitosaurus in 1902. Stegosaurus priscus, described by Nopcsa in 1911, was reassigned to Lexovisaurus,[16] and is now the type species of Loricatosaurus.[20]
