Anatibetites is an extinct genus of cephalopods belonging to the Ammonite subclass.
Himalayasaurus is an extinct genus of ichthyosaur from the Late Triassic Qulonggongba Formation of Tibet. The type species Himalayasaurus tibetensis was described in 1972 on the basis of fragmentary remains, including teeth, limb bones, and vertebrae. The entire body length of Himalayasaurus is estimated to have been over 15 metres (49 ft) in length. Himalayasaurus has since been considered a nomen dubium or "dubious name" because of the lack of features that set it apart from other ichthyosaurs, although the presence of distinct cutting edges on its teeth have more recently been proposed as a unique feature of the genus. Himalayasaurus belongs to the family Shastasauridae, which includes other large-bodied Triassic ichthyosaurs like Shonisaurus.
Platyceras is a genus of extinct Paleozoic sea snails, marine gastropod mollusks in the family Platyceratidae. This genus is known from the Silurian to the Middle Triassic periods and especially abundant in the Devonian and Carboniferous. It is the type genus of the family Platyceratidae.
Sagenopteris is a genus of extinct seed ferns from the Triassic to late Early Cretaceous.
Deltasaurus pustulatus is an amphibian fossil species of the family Rhytidosteidae. The temnospondyl hunted invertebrates and fish during the late stage Triassic epoch, and somewhat resembles the only other species of the eastern Gondwanan genus Deltasaurus. The only known evidence of the species was discovered in a drill core in Southwest Australia, near Geraldton, a seemingly improbable event that produced the only known example of Triassic vertebrate fauna in the ecologically exceptional region's Kockatea Formation.
Angusaurus is an extinct genus of trematosaurian temnospondyl within the family Trematosauridae.
Chomatobatrachus is a genus of prehistoric temnospondyl from the Triassic.
Gonioglyptus is an extinct genus of trematosaurian temnospondyl within the family Trematosauridae. It is known from the Early Triassic Panchet Formation of India. It contains two species: G. longirostris and G. fragilis. The species G. kokeni from Pakistan has since been reclassified into Aphaneramma.
Ptychoceratodus is an extinct genus of lungfish living from Early Triassic to Middle Jurassic. It was established by Otto Jaekel for one species, transferred from Ceratodus genus. Type species is P. serratus from the Middle Triassic of Switzerland and Germany. Ptychoceratodus had two pairs of massive dental plates, bearing 4-6 acute ridges. Its skull roof was composed from massive, plate-like bones. In the central part of skull roof was localized an unossified fenestra. Most of the Ptychoceratodus findings are isolated dental plates, some associated with jaws. Other parts of skull or postcranial skeleton are relatively rarely found as fossils. The anatomy of skull is the best recognized in P. serratus, whereas less complete cranial material is available also for P. concinuus, P. phillipsi, and P. rectangulus. Although Ptychoceratodus is known exclusively from the Triassic and Jurassic, there were also Cretaceous specimens referred to this genus. However, they are more often regarded as representants of Metaceratodus. Ptychoceratodus is the only member of the family Ptychoceratodontidae. The first named species is P. phillipsi by Louis Agassiz in 1837 as a species of Ceratodus and later moved to Ptychoceratodus genus. Occurrences of Ptychoceratodus come mainly from Europe. However, occurrences from other continents suggest it was dispersed globally during the Triassic. After 2010, the new fossil material behind the Europe was reported from South America, India, and Greenland
Paraceratodus is an extinct genus of prehistoric lungfish. Only one species, P. germaini, is known from the latest Permian or earliest Triassic period of Madagascar. Phylogenetic evidence supports it being the most basal member of the suborder Ceratodontoidei, which contains modern lungfish, and as with the rest of the order it likely diverged during the late Carboniferous.
Tranodis is an extinct genus of prehistoric sarcopterygians or lobe-finned fish. It was a lungfish from the Upper Mississippian of North America.
Pessosaurus is an extinct genus of ichthyosaurs which existed during the Middle Triassic period.
The Mercia Mudstone Group is an early Triassic lithostratigraphic group which is widespread in Britain, especially in the English Midlands—the name is derived from the ancient kingdom of Mercia which corresponds to that area. It is frequently encountered in older literature as the Keuper Marl or Keuper Marl Series.
Hedenstroemia is an extinct genus of Early Triassic (Olenekian) cephalopods in the ammonoid order Ceratitida. They were nektonic carnivores.
The Sulphur Mountain Formation is a geologic formation of Early to Middle Triassic age. It is present on the western edge of the Western Canada Sedimentary Basin in the foothills and Rocky Mountains of western Alberta and northeastern British Columbia. It includes marine fossils from the time shortly after the Permian-Triassic extinction event.
Ophiceras is an extinct genus of smooth, evolute ceratitid ammonites from the Griesbachian, with a rounded venter. Fossils of the genus have been found in Armenia, Azerbaijan, China, Greenland, and India.
Sturia is a genus of ceratitid ammonoids from the Lower Triassic with an ammonitic suture.
Misikella is an extinct genus of conodonts.
The Spray River Group is a stratigraphic unit of Triassic age. It is present on the western edge of the Western Canada Sedimentary Basin in the foothills and Rocky Mountains of western Alberta. It was originally described as the Spray River Formation by E.M. Kindle in 1924 and was later raised to group status. Its type section is located in the Spray River gorge at the southern end of Sulphur Mountain.
