Stegosaurus stenops, meaning "narrow-faced roof lizard", was named by Marsh in 1887, [11] with the holotype having been collected by Marshall Felch at Garden Park, north of Cañon City, Colorado, in 1886. This is the best-known species of Stegosaurus, mainly because its remains include at least one complete articulated skeleton. It had ...
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. [54] Stegosaurus stenops had four dermal spikes, each about 60–90 cm (2–3 ft) long. Discoveries of ...

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.
S. armatus is both the first Stegosaurus to be discovered and the type species. [44] Its type specimen is poorly preserved, incomplete, and lacks diagnostic features. [43] It has been considered dubious, with S. stenops as the neotype species for the genus. [43] S. stenops [14] Colorado, Utah and Wyoming, Brushy Basin member [16] [14] [9] [45]
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 ...
Description. Apex is the largest and most complete known Stegosaurus skeleton, with 254 bones preserved out of approximately 319. It measures 3.4 metres (11 ft) in height and 8.2 metres (27 ft) in length. [1] The specimen is 150 million years old, dating to the Late Jurassic epoch. [2] The exact species it belongs to is not known.
The nearly complete fossilized remains of a stegosaurus fetched $44.6 million at auction Wednesday, Sotheby's said. The fossil, dubbed “Apex,” is considered to be among the most complete ever ...
