Stegouros
''Stegouros'' (, meaning "roofed tail") is a genus of ankylosaurian dinosaur from the Late Cretaceous Dorotea Formation of southern Chile. The genus contains a single species, ''Stegouros elengassen'', known from a semi-articulated, near-complete skeleton. Discovery In February 2018, the skeleton of a small ankylosaur was recovered by a team of Texan researchers near the Río de las Chinas valley of Ultima Esperanza province in the Magallanes y la Antártica Chilena region of southern Chile. In 2021, the type species ''Stegouros elengassen'' was named and described by Sergio Soto-Acuña ''et al''. The generic name combines the Greek ''stegos'', meaning "roof" and ''oura'', meaning "tail", referring to the roof-like covering of the tail end. The specific name ''elengassen'' is derived from an armoured creature in the mythology of the Aónik’enk, the indigenous inhabitants of the region where the holotype was discovered. The holotype, CPAP-3165, was found in a layer of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Antarctopelta
''Antarctopelta'' ( ; meaning 'Antarctic shield') was a genus of ankylosaurian dinosaur with one known species, ''A. oliveroi'', which lived in Antarctica during the Late Cretaceous Period. It was a medium-sized ankylosaur, reaching 4 meters (13 ft) in length or more, and showed characteristics of two different families, making more precise classification difficult. The single known fossil specimen was discovered on James Ross Island in 1986, constituting the first dinosaur remains ever discovered on Antarctica, although it is the second dinosaur from the continent to be formally named. Discovery and naming The holotype (specimen used as the basis for the taxon) is the only known example of this genus and species, and was the first dinosaur ever found in Antarctica. It consists of three isolated teeth, part of the lower jaw with another tooth ''in situ'', some other skull fragments, vertebrae (neck, back, hips and tail), some partial limb bones (scapula, ilium and femur), t ...

Ankylosauria
Ankylosauria is a group of herbivorous dinosaurs of the order Ornithischia. It includes the great majority of dinosaurs with armor in the form of bony osteoderms, similar to turtles. Ankylosaurs were bulky quadrupeds, with short, powerful limbs. They are known to have first appeared in the Middle Jurassic, and persisted until the end of the Cretaceous Period. The two main families of Ankylosaurs, Nodosauridae and Ankylosauridae are primarily known from the Northern Hemisphere, but the more basal Parankylosauria are known from southern Gondwana during the Cretaceous. Ankylosauria was first named by Henry Fairfield Osborn in 1923.Osborn, H. F. (1923). "Two Lower Cretaceous dinosaurs of Mongolia." ''American Museum Novitates'', 95: 1–1/ref> In the Linnaean classification system, the group is usually considered either a suborder or an infraorder. It is contained within the group Thyreophora, which also includes the stegosaurs, armored dinosaurs known for their combination of plate ...

Kunbarrasaurus
''Kunbarrasaurus'' is an extinct genus of small herbivorous ankylosaurian dinosaur from the Cretaceous of Australia. Discovery In November 1989, at Marathon Station near Richmond, Queensland, the skeleton was discovered of an ankylosaurian. In January 1990 it was secured by a team led by Ralph Molnar. In 1996, in a provisional description, Molnar concluded that it could be referred to the genus ''Minmi'' as a ''Minmi'' sp. Subsequently, the specimen was further prepared by an acid bath and investigated by a CAT scan. The new information led to the conclusion that the species could be named in a separate genus of ankylosaur. In 2015, Lucy G. Leahey, Ralph E. Molnar, Kenneth Carpenter, Lawrence M. Witmer and Steven W. Salisbury named and described the type species ''Kunbarrasaurus ieversi''. The genus name is derived from ''Kunbarra'' - the word for 'shield' in the Mayi language of the local Wunumara people. The specific name ''ieversi'' honours Mr Ian Ivers, the property m ...

Postcranial Axial Skeleton Of Stegouros Elengassen
Postcrania (postcranium, adjective: postcranial) in zoology and vertebrate paleontology is all or part of the skeleton apart from the skull. Frequently, fossil remains, e.g. of dinosaurs or other extinct tetrapods, consist of partial or isolated skeletal elements; these are referred to as ''postcrania''. There is some disagreement over whether the skull and skeleton belong to the same or different animals. One example is the case of a Cretaceous sauropod skull of ''Nemegtosaurus'' found in association with the postcranial skeleton ''Opisthocoelicaudia ''Opisthocoelicaudia'' is a genus of sauropod dinosaur of the late Cretaceous, Late Cretaceous Period discovered in the Gobi Desert of Mongolia. The type species is ''Opisthocoelicaudia skarzynskii''. A well-preserved skeleton lacking only the ...''. In paleoanthropological studies, reconstruction of relationship between various species/remains is considered to be better supported by cranial characters rather than postcranial c ...

Comparison Of Teeth And Dentary Of Stegouros Elengassen And Antarctopelta Oliveroi
Comparison or comparing is the act of evaluating two or more things by determining the relevant, comparable characteristics of each thing, and then determining which characteristics of each are similar to the other, which are different, and to what degree. Where characteristics are different, the differences may then be evaluated to determine which thing is best suited for a particular purpose. The description of similarities and differences found between the two things is also called a comparison. Comparison can take many distinct forms, varying by field: To compare things, they must have characteristics that are similar enough in relevant ways to merit comparison. If two things are too different to compare in a useful way, an attempt to compare them is colloquially referred to in English as "comparing apples and oranges." Comparison is widely used in society, in science and in the arts. General usage Comparison is a natural activity, which even animals engage in when deci ...
