The AMNH mount is cast and on display at the Field Museum, which didn't collect any Stegosaurus skeletons during the Second Dinosaur Rush.There has been debate about whether the tail spikes were used for display only, as posited by Gilmore in 1914 [14] or used as a weapon. The other, Stegosaurus sulcatus, was named based on a left forelimb, scapula, left femur, several vertebrae, and several plates and dermal armor elements (USNM V 4937) collected in 1883. mjosi) and would range from the Late Jurassic of North America and Europe to the Early Cretaceous of Asia. 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.

S. stenops preserves 46 caudal vertebrae, and up to 49, and along the series both the centrums and the neural spines become smaller, until the neural spines disappear at caudal 35. The Armored Dinosaurs; 2001, Chapter: "Posttraumatic Chronic Osteomyelitis in Stegosaurus dermal spikes". The tail appears to have been held well clear of the ground, while the head of Stegosaurus was positioned relatively low down, probably no higher than 1 metre (3. S. stenops is known from at least 50partial skeletons of adults and juveniles, one complete skull, and four partial skulls. Due to their distinctive combination of broad, upright plates and tail tipped with spikes, Stegosaurus is one of the most recognizable kinds of dinosaurs.Arthur Lakes made another discovery later in 1879 at Como Bluff in Albany County, Wyoming, the site also dating to the Upper Jurassic of the Morrison Formation, when he found several large Stegosaurus fossils in August of that year. Farlow JO, Thompson CV, Rosner DE, 1976; "Plates of the dinosaur Stegosaurus:Forced convection heat loss fins? Susannah Maidment and colleagues in 2008 proposed extensive alterations to the taxonomy of Stegosaurus. The Carnegie Museum in Pittsburgh on the other hand collected many Stegosaurus specimens, first at Freezout Hills in Carbon County, Wyoming in 1902–03. Although it makes no actual appearance in the film, the name is used; it is on one of the embryo vials stolen (misspelled as 'Steg asaurus').

In the past, some palaeontologists, notably Robert Bakker, have speculated the plates may have been mobile to some degree, although others disagree. As further and complete plates were found, their form showed that they stood on edge, rather than lying flat. 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. Debate has been going on about whether the tail spikes were used for display only, as posited by Gilmore in 1914 [7] or used as a weapon.

Bakker suggested in 1986 that the plates were covered in horn comparing the surface of the fossilized plates to the bony cores of horns in other animals known or thought to bear horns.
