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 ...
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.

Its fossils were found in the Xinminbao Group near Heishan in Gansu Province in China. These fossils consist of fragmentary material, including dermal spine elements.
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 ...
