Stegosaurus longispinus was named by Charles W. Gilmore in 1914 based on a fragmentary postcranial skeleton that has largely been lost. [61] [8] It is now the type species of the genus Alcovasaurus, though it has been referred to Miragaia. [62] [61] Stegosaurus madagascariensis from Madagascar is known solely from teeth and was described by ...
Stegosauria is a group of herbivorous ornithischian dinosaurs that lived during the Jurassic and early Cretaceous periods. Stegosaurian fossils have been found mostly in the Northern Hemisphere, predominantly in what is now North America, Europe, Africa, South America and Asia. Their geographical origins are unclear; the earliest unequivocal ...
Skeletal mount of Stegosaurus. This timeline of stegosaur research is a chronological listing of events in the history of paleontology focused on the stegosaurs, the iconic plate-backed, spike-tailed herbivorous eurypod dinosaurs that predominated during the Jurassic period. The first scientifically documented stegosaur remains were recovered ...
Hesperosaurus. Hesperosaurus (meaning "western lizard", from Classical Greek ἕσπερος (hesperos) "western" and σαυρος (sauros) "lizard") is a herbivorous stegosaurian dinosaur from the Kimmeridgian age of the Jurassic period, approximately 156 million years ago.

The hole perfectly matches a thagomizer spike. [1] A thagomizer (/ ˈθæɡəmaɪzər /) is the distinctive arrangement of four spikes on the tails of stegosaurian dinosaurs. These spikes are believed to have been a defensive measure against predators. [2][1] The arrangement of spikes originally had no distinct name.
The clade Stegosauridae is composed of the genera Stegosaurus, Dacentrurus, Miragaia, Loricatosaurus, and Kentrosaurus, with the last considered to be at the base of the clade. The stegosaurids like all other stegosaurians were quadrupedal herbivores that exhibited the characteristic stegosaurian dorsal dermal plates.
Thyreophora ("shield bearers", often known simply as "armored dinosaurs") is a group of armored ornithischian dinosaurs that lived from the Early Jurassic until the end of the Cretaceous. Thyreophorans are characterized by the presence of body armor lined up in longitudinal rows along the body.
