Stegosaurus
Stegosaurus is a genus of herbivorous thyreophoran dinosaur. Fossils of this genus date to the Late Jurassic period, between 155 and 150 million years ago. Only three species are universally recognized; S. stenops, S. ungulatus and S. sulcatus. Due to their distinctive combination of broad, upright plates and tail tipped with spikes, StEGosaurus is one of the most recognizable kinds of dinosaurs.
About Stegosaurus in brief
Stegosaurus is a genus of herbivorous thyreophoran dinosaur. Fossils of this genus date to the Late Jurassic period, between 155 and 150 million years ago. Stegosaurus would have lived alongside dinosaurs such as Apatosaurus, Diplodocus, Brachiosaurus, Allosaurus, and Ceratosaurus. Only three species are universally recognized; S. stenops, S. ungulatus and S. sulcatus. Due to their distinctive combination of broad, upright plates and tail tipped with spikes, StEGosaurus is one of the most recognizable kinds of dinosaurs. StEGosaurians were first identified during the Bone Wars by Othniel Charles Marsh in 1877. Despite its popularity in books and film, mounted skeletons did not become a staple of major natural history museums until the mid-20th century. Many museums have had to assemble composite displays from several different specimens due to a lack of complete skeletons. The next species to be named was S. marshi, which was reclassified in the new genus Hoplitosaurus in 1901. The first attempt at a complete reconstruction of S. stenops was published in 1891 by Marsh, from a missing parts filled in with missing parts of S ops. The specimen was later lost, and Marsh later lost 18 new species: stenops duplex, and S sul catus. He later re-examined a nearly complete specimen of stenops and articulated the type specimen of Segosaurus armatus. This first reconstruction, of Sul catus, was published by Marsh in 1896, and was the first time a complete skeleton of a stegosaurian was published.
It is generally agreed that their spiked tails were most likely used for defense against predators, while their plates may have been used primarily for display, and secondarily for thermoregulatory functions. It would be many years before the true appearance of these animals, including their posture and plate arrangement, became well understood. One species is the largest known of all the Stegosaurosaurians, and it is called S. armatus, or ‘roof lizard’ The first known skeletons were fragmentary and the bones were scattered, and they were found in the Morrison Formation of the western U.S. and Portugal. The remains of over 80 individual animals have been found. A wealth of Steg dinosaurs were recovered over the next few years, and a wealth of material was recovered from 1877 to 1897. In 1881, Marsh named a third species Stegosaurs affinis, based only on a hip bone, and later lost it in a fire. In 1987, Marsh published several papers on the genus from 1887 to 1897, and named three species: S. stegosaurus, stenops,. S. duplex,. and S sulcatus, which he later later lost he later lost. The last species of Stegaosaurus to be identified is S. scepsoi, named by Frederick Lucas in 1901, and the next year it was re-classified as’marshi’
