One of the major subjects of books and articles about Stegosaurus is the plate arrangement. [18] The argument has been a major one in the history of dinosaur reconstruction. Four possible plate arrangements have been proposed over the years: The plates lie flat along the back, as a shingle-like armor. This was Marsh's initial interpretation ...
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 ...
Its array of plates and spikes has been the subject of much speculation. The spikes were most likely used for defense, while the plates have also been proposed as a defensive mechanism, as well as having display and thermoregulatory functions. Stegosaurus had a relatively low brain-to-body mass ratio. It had a short neck and small head, meaning ...
This Stegosaurus fossil was found in Colorado and fetched a record $44.6 million at a Sotheby's auction in July. The buyer has loaned it to the New York museum, one of the leading natural history ...
How big is stegosaurus skeleton? Why is it named Apex? Find the answers to those questions and more.
The stegosaurus was one of the world's most distinctive dinosaurs, featuring pointy plates on its back. Hatton has called Apex “a coloring book dinosaur,” for its well-preserved features.
Stegosaurus fossils have potential sexual dimorphism in the shape of their back plates, with males having rounder and wider back plates while female's have taller more diamond shaped back plates. [13] These plates may have displayed colors and been a sign of health in males, while female's plates acted as defense, like a cow's horns. [13]
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.
