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 ...
Those would have been useful as protection against meat-eating dinosaurs like Allosaurus. This Stegosaurus fossil was found in Colorado and fetched a record $44.6 million at a Sotheby's auction in ...
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.
Galton and Carpenter considered Alcovasaurus a member of the Stegosauridae, not more closely related to Kentrosaurus than to Stegosaurus. [1] However, a 2017 phylogeny of stegosaurids by Thomas Raven and Susannah Maidment found that Alcovasaurus lacked the fusion between the trochanters of the femur seen in adult eurypodans (stegosaurians and ankylosaurians), which means that it cannot be ...
This too supports the theory that the spikes were used in combat. There is also evidence for Stegosaurus defending itself, in the form of an Allosaurus tail vertebra with a partially healed puncture wound that fits a Stegosaurus tail spike. [53] Stegosaurus stenops had four dermal spikes, each about 60–90 cm (2–3 ft) long. Discoveries of ...
