"The plated dinosaur Stegosaurus longispinus Gilmore, 1914 (Dinosauria: Ornithischia; Upper Jurassic, western USA), type species of Alcovasaurus n. gen". Neues Jahrbuch für Geologie und Paläontologie - Abhandlungen. 279 (2): 185–208. doi: 10.1127/njgpa/2016/0551. Susannah Maidment and colleagues in 2008 proposed extensive alterations to the taxonomy of Stegosaurus. They advocated synonymizing S.stenops and S.ungulatus with S.armatus, and sinking Hesperosaurus and Wuerhosaurus into Stegosaurus, with their type species becoming Stegosaurus mjosi and Stegosaurus homheni, respectively. They regarded S.longispinus as dubious. Thus, their conception of Stegosaurus would include three valid species ( S.armatus, S.homheni, and S.mjosi) and would range from the Late Jurassic of North America and Europe to the Early Cretaceous of Asia. [22] However, this classification scheme was not followed by other researchers, and a 2017 cladistic analysis co-authored by Maidment with Thomas Raven rejects the synonymy of Hesperosaurus with Stegosaurus. [2] [57] In 2015, Maidment et al. revised their suggestion due to the recognition by Galton of S. armatus as a nomen dubium and its replacement by S. stenops as type species. [26] Doubtful species and junior synonyms [ edit ] Stegosaurus longispinus was named by Charles W. Gilmore in 1914 based on a fragmentary postcranial skeleton that has largely been lost. [61] [7] It is now the type species of the genus Alcovasaurus, though it has been referred to Miragaia. [62] [61]Delta Kite Pterosaur Dinosaur really comes to life with a slow soaring flight with a glancing eye as if searching the ground for dinner along with its large and unusual size it’s a real eye grabber Many of the species initially described have since been considered to be invalid or synonymous with earlier named species, [5] leaving two well-known and one poorly known species. Confirmed Stegosaurus remains have been found in the Morrison Formation's stratigraphic zones 2–6, with additional remains possibly referrable to Stegosaurus recovered from stratigraphic zone 1.

Most of the information known about Stegosaurus comes from the remains of mature animals; more recently, though, juvenile remains of Stegosaurus have been found. One subadult specimen, discovered in 1994 in Wyoming, is 4.6m (15.1ft) long and 2m (6.6ft) high, and is estimated to have weighed 1.5-2.2metric tons (1.6-2.4short tons) [35] while alive. It is on display in the University of Wyoming Geological Museum. [36] Skull [ edit ] S.stenops skull cast, Natural History Museum of Utah

Soon after its discovery, Marsh considered Stegosaurus to have been bipedal, due to its short forelimbs. [69] He had changed his mind, however, by 1891, after considering the heavy build of the animal. [11]a b c d e f "Denver's Fighting Dinosaurs". EXTINCT MONSTERS. August 14, 2015 .
