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 ...

Thagomizer on mounted Stegosaurus tail. A thagomizer (/ ˈ θ æ ɡ ə m aɪ z ər /) 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. [1] [2] The arrangement of spikes originally had no distinct name.
The most derived species, like Stegosaurus, Hesperosaurus and Wuerhosaurus, have very large and flat back plates. Stegosaurid plates have a thick base and central portion, but are transversely thin elsewhere. The plates become remarkably large and thin in Stegosaurus. They are found in varying sizes along the dorsum, with the central region of ...
According to Madzia et al., Thyreophora is defined as the largest clade containing Ankylosaurus magniventris and Stegosaurus stenops but not Iguanodon bernissartensis and Triceratops horridus. [2] They also defined the less inclusive Eurypoda as "the smallest clade containing Ankylosaurus magniventris and Stegosaurus stenops " to include the ...

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 authors stressed that the only synapomorphy, shared derived trait, supporting the Dacentrurus-Stegosaurus clade was the possession of the long cervical postzygapophyses, and that these are in fact unknown for Dacentrurus itself, so that its close position to Stegosaurus was merely based on the new data provided by the description of ...
