Paratypothorax
''Paratypothorax'' is an extinct genus of aetosaur, known from a single species, ''Paratypothorax andressorum''. It was a broadly distributed member of the group found in Germany, North America, and possibly parts of Gondwana. The best specimens come from Germany, though for more than a century they were mistakenly considered phytosaur armor. ''Paratypothorax'' was a large and wide-bodied typothoracine aetosaur, as well as the namesake of the tribe Paratypothoracisini. Discovery and distribution ''Paratypothorax'' was first known from specimens collected from the Heslach area near Stuttgart in Germany. These hail from the Stubensandstein (also known as the Löwenstein Formation), a mid- Norian age geological unit. Heslach has also produced many fossils of a smaller aetosaur, ''Aetosaurus''. The holotype specimen of ''Paratypothorax'', SMNS 5721, consists of a series of articulated osteoderms alongside a few hip and leg bones. Large osteoderms of ''Paratypothorax'' were lo ...

Aetosaur
Aetosaurs () are heavily armored reptiles belonging to the extinct order Aetosauria (; from Greek, (aetos, "eagle") and (, "lizard")). They were medium- to large-sized omnivorous or herbivorous pseudosuchians, part of the branch of archosaurs more closely related to crocodilians than to birds and other dinosaurs. All known aetosaurs are restricted to the Late Triassic, and in some strata from this time they are among the most abundant fossil vertebrates. They have small heads, upturned snouts, erect limbs, and a body ornamented with four rows of plate-like osteoderms (bony scutes). Aetosaur fossil remains are known from Europe, North and South America, parts of Africa, and India. Since their armoured plates are often preserved and are abundant in certain localities, aetosaurs serve as important Late Triassic tetrapod index fossils. Many aetosaurs had wide geographic ranges, but their stratigraphic ranges were relatively short. Therefore, the presence of particular aetosaurs can ...

Paratypothoracisini
Paratypothoracini is a clade of aetosaurs within the group Typothoracinae. It is a node-based taxon that includes '' Rioarribasuchus'' (='' Heliocanthus''), '' Paratypothorax'', '' Tecovasuchus'', and all descendants of their most recent common ancestor. The clade was first named in 2007 under the spelling Paraypothoracisini, after its namesake ''Paratypothorax''. However, this spelling was based on incorrect taxonomic nomenclature, and the clade's name was corrected to Paratypothoracinae in 2016. All synapomorphies that diagnose Paratypothoracini can be found in their osteoderm Osteoderms are bony deposits forming scales, plates, or other structures based in the dermis. Osteoderms are found in many groups of extant and extinct reptiles and amphibians, including lizards, crocodilians, frogs, temnospondyls (extinct amp ...s. The paramedian osteoderms are wide and lie flat, without any apparent flexure (a trait convergent with some desmatosuchin aetosaurs) The paramedians po ...

Fleming Fjord Formation
The Fleming Fjord Formation, alternatively called the Fleming Fjord Group is an Upper Triassic geological formation in the northeastern coast of Jameson Land, Greenland. It consists of terrestrial sediments and is known for its fossil content. Description It is of Norian to Rhaetian age and is subdivided into three members; at the base the Edderfugledal Member, followed by the Malmros Klint Member with the Ørsted Dal Member at the top. It was deposited in a large shallow to ephemeral lake. Paleobiota The fauna of Fleming Fjord is diverse, including sauropodomorph dinosaurs, pterosaurs, temnospondyls, mammaliaforms, aetosaurs, and other taxa. Freshwater unionid bivalves and conchostracans have been reported from the Malmros Klint Member. Fish Lungfish, actinopterygian, and chondrichthyan teeth have been reported from the Malmros Klint Member. Amphibians Reptiles Besides the forms described below, a diverse ichnofauna of small and large tracks has also been reported ...

Typothoracinae
Typothoracinae is a clade of aetosaurs within the subfamily Aetosaurinae. It was originally defined as a stem-based taxon including all aetosaurs closer to ''Typothorax'' than to ''Stagonolepis'' or ''Desmatosuchus''. This definition was later expanded to specifically exclude ''Aetosaurus''; as of 2016, Typothoracinae is defined as the least inclusive clade containing ''Typothorax'' and ''Paratypothorax'', but not ''Aetosaurus,'' ''Stagonolepis'', or ''Desmatosuchus''. The clade was first named in 2007 under the spelling Typothoracisinae, after its namesake ''Typothorax''. However, this spelling was based on incorrect taxonomic nomenclature, and the clade's name was corrected to Typothoracinae in 2016. Typothoracines can be distinguished by their wide bodies. The transverse processes of the dorsal (trunk) vertebrae are reinforced and elongated, more than twice the width of the centrum. Their neural spines, on the other hand, are short. The overlying carapace A carapace is a Do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belodon
''Belodon'' (meaning "arrow tooth") is a genus of phytosaur, a crocodile-like reptile that lived during the Triassic. Its fossils have been found in Europe and elsewhere. The type species, ''Belodon plieningeri'', was named by prolific German paleontologist Christian Erich Hermann von Meyer in 1844. Many other species were also named, among them ''Belodon buceros'' (named by Edward Drinker Cope in 1881),Cope, E.D. (1881). "''Belodon'' in New Mexico". ''American Naturalist'' 15: 922-923. ''Belodon kapfii'' (von Meyer, 1861), ''Belodon lepturus'' (Cope, 1870),Cope, E.D. (1870). "Reptilia of the Triassic Formation of the United States". ''American Naturalist'' 4: 562-563.

Aetosaurus
''Aetosaurus'' is an extinct genus of pseudosuchian reptile belonging to the order Aetosauria. It is generally considered to be the most primitive aetosaur. Three species are currently recognized: ''A. ferratus'', the type species from Germany and Italy; ''A. crassicauda'' from Germany; and ''A. arcuatus'' from eastern North America. Additional specimens referred to ''Aetosaurus'' have been found in the Chinle Group of the southwestern United States, and the Fleming Fjord Formation of Greenland. Specimens of ''Aetosaurus'' occur in Norian-age strata. Description ''Aetosaurus'' was a small, primitive aetosaur. Unlike more derived aetosaurs such as ''Desmatosuchus'' or '' Typothorax'', the carapace was long and narrow and lacked spikes. The paramedian scutes that covered the back (with one row on each side of the vertebrae) are considerably wider than they are long. The lateral scutes, which are beneath the paramedians and formed a row on either side of the animal, do not bear a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carnian
The Carnian (less commonly, Karnian) is the lowermost stage of the Upper Triassic Series (or earliest age of the Late Triassic Epoch). It lasted from 237 to 227 million years ago (Ma). The Carnian is preceded by the Ladinian and is followed by the Norian. Its boundaries are not characterized by major extinctions or biotic turnovers, but a climatic event (known as the Carnian pluvial episode characterized by substantial rainfall) occurred during the Carnian and seems to be associated with important extinctions or biotic radiations. Stratigraphic definitions The Carnian was named in 1869 by Mojsisovics. It is unclear if it was named after the Carnic Alps or after the Austrian region of Carinthia (''Kärnten'' in German) or after the Carnia historical region in northwestern Italy. The name, however, was first used referring to a part of the Hallstatt Limestone cropping out in Austria. The base of the Carnian Stage is defined as the place in the stratigraphic record where t ...

Chinle Group
The Chinle Formation is an Upper Triassic continental geological formation of fluvial, lacustrine, and palustrine to eolian deposits spread across the U.S. states of Nevada, Utah, northern Arizona, western New Mexico, and western Colorado. In New Mexico, it is often raised to the status of a geological group, the Chinle Group. Some authors have controversially considered the Chinle to be synonymous to the Dockum Group of eastern Colorado and New Mexico, western Texas, the Oklahoma panhandle, and southwestern Kansas. The Chinle Formation is part of the Colorado Plateau, Basin and Range, and the southern section of the Interior Plains.GEOLEX database entry for Chinle USGS (viewed 19 March 2006) A probable separate depositional basin within the Chinle is found in northwestern Colorado and northeastern Ut ...
