Kentrosaurus
Kentrosaurus (ˌkɛntroʊˈsɔːrəs ; prickle lizard) is a genus of stegosaurid dinosaur from the Late Jurassic in Lindi Region of Tanzania. The type species is K. aethiopicus, named and described by German palaeontologist Edwin Hennig in 1915. Often thought to be a "primitive" member of the Stegosauria, several recent cladistic analyses find it as more derived than many other stegosaurs, and a close relative of Stegosaurus from the North American Morrison Formation within the Stegosauridae. Fossils of K.
Hesperosaurus
Hesperosaurus (meaning "western lizard", from Classical Greek ἕσπερος (hesperos) "western" and σαυρος (sauros) "lizard") is a herbivorous stegosaurian dinosaur from the Kimmeridgian age of the Jurassic period, approximately 156 million years ago. Fossils of Hesperosaurus have been found in the state of Wyoming and Montana in the United States of America since 1985. The type species Hesperosaurus mjosi was named in 2001. It is from an older part of the Morrison Formation, and so a little older than other Morrison stegosaurs.
Miragaia longicollum
Miragaia (named after Miragaia, the parish in Portugal and geologic unit where its remains were found) is a long-necked stegosaurid dinosaur. Its fossils have been found in Upper Jurassic rocks in Portugal (Lourinhã Formation, Sobral Unit) and possibly also Wyoming, United States (Morrison Formation). Miragaia has the longest neck known for any stegosaurian, which included at least seventeen vertebrae. Miragaia is based on holotype ML 433, a nearly complete anterior half of a skeleton with partial skull (the first cranial material for a European stegosaurid).
Paranthodon
Paranthodon (pəˈrænθədɒn ) is a genus of stegosaurian dinosaur that lived in what is now South Africa during the Early Cretaceous, between 139 and 131 million years ago. Discovered in 1845, it was one of the first stegosaurians found. Its only remains, a partial skull, isolated teeth, and fragments of vertebrae, were found in the Kirkwood Formation. British paleontologist Richard Owen initially identified the fragments as those of the pareiasaur Anthodon.
Stegosaurus
Stegosaurus (ˌstɛɡəˈsɔːrəs; roof-lizard) is a genus of herbivorous, four-legged, armored dinosaur from the Late Jurassic, characterized by the distinctive kite-shaped upright plates along their backs and spikes on their tails. Fossils of the genus have been found in the western United States and in Portugal, where they are found in Kimmeridgian- to Tithonian-aged strata, dating to between 155 and 145 million years ago. Of the species that have been classified in the upper Morrison Formation of the western US, only three are universally recognized: S.
