Qantas (genus)
''Qantas'' is a genus of trematosauroid temnospondyl from the Early Triassic. Fossils have been found from the Kamennyi Yar Formation in Borsky District, Samara Oblast. The type species ''Qantas samarensis'' was named in 2012 and placed in the family Benthosuchidae, as it was viewed as a close relative of ''Benthosuchus''. The subfamily Qantasinae was established to include ''Qantas'', and possibly the genus ''Tirraturhinus''. ''Qantas'' is named after the Australian airline Qantas, which supported the original study of the fossils.

Early Triassic
The Early Triassic is the first of three epochs of the Triassic Period of the geologic timescale. It spans the time between Ma and Ma (million years ago). Rocks from this epoch are collectively known as the Lower Triassic Series, which is a unit in chronostratigraphy. The Early Triassic is the oldest epoch of the Mesozoic Era. It is preceded by the Lopingian Epoch (late Permian, Paleozoic Era) and followed by the Middle Triassic Epoch. The Early Triassic is divided into the Induan and Olenekian ages. The Induan is subdivided into the Griesbachian and Dienerian subages and the Olenekian is subdivided into the Smithian and Spathian subages. The Lower Triassic series is coeval with the Scythian Stage, which is today not included in the official timescales but can be found in older literature. In Europe, most of the Lower Triassic is composed of Buntsandstein, a lithostratigraphic unit of continental red beds. The Early Triassic and partly also the Middle Triassic span the in ...

Capitosauridae
Mastodonsauridae is a family of Capitosauroidea, capitosauroid temnospondyls. Fossils belonging to this family have been found in North America, Greenland, Europe, Asia, and Australia. The family Capitosauridae is synonym (taxonomy), synonymous with Mastodonsauridae. Description Size Mastodonsaurids were generally large amphibians, with some length estimates ranging from 3 to 6 meters. Some genera, like ''Mastodonsaurus'' and ''Cyclotosaurus'' were specially large, reaching at least 4 meters or more. Other genera like ''Parotosuchus'' and ''Paracyclotosaurus'' only reached 2 meters or more in length, but it's still pretty large compared to modern-day amphibians. Distinguishing features Some mastodonsaurids including ''Parotosuchus'' were covered in a scaly skin, unlike the smooth skin of modern-day amphibians, and probably moved with an eel-like motion in the water. Another peculiar mastodonsaurid is ''Sclerothorax'', with unusual features including its elongated neural spines. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trematosauridae
Trematosauridae are a family of large marine temnospondyl amphibians with many members. They first appeared during the Induan age of the Early Triassic, and existed until around the Carnian stage of the Late Triassic, although by then they were very rare. By the Middle Triassic they had become widespread throughout Laurasia and Gondwana with fossils being found in Europe, Asia, Madagascar, and Australia. They are one of the most derived families of the Trematosauroidea superfamily in that they are the only family that have fully marine lifestyles. Long, slender snouts that are characteristic of the trematosaurids, with some members having rostrums resembling those of modern-day gavials. Traditionally, two subfamilies within Trematosauridae can be identified, the relatively short-nosed Trematosaurinae and the long-nosed Lonchorhynchinae._A_third_subfamily,_Tertreminae.html" ;"title="....

Vladlenosaurus
''Vladlenosaurus'' is an extinct genus of capitosaur from Russia. It lived during the late Vetlugian (Early Triassic). Based on the type of deposits it was found in, ''Vladlenosaurus'' probably inhabited lacustrine, or lake, habitats. The type species is ''V. alexeyevi'', named in 2000. Description Unlike the flatter, more rounded snouts of other capitosaurs, ''Vladlenosaurus'' had a wedge-shaped snout. This characteristic is also seen in trematosaurians, although it was independently acquired in both cases as a result of convergent evolution. Classification ''Vladlenosaurus'' is similar in appearance to the benthosuchids, a group of trematosauroid temnospondyls, but is more closely related to mastodonsauroids. Among capitosaurs, it shares many features with the basal form ''Wetlugasaurus'', also from the Early Triassic of Russia. ''Vladlenosaurus alexeyevi'' was even considered to be a species of ''Wetlugasaurus'' in a 2006 study. In a 2011 phylogenetic analysis, the first ...

Selenocara
''Selenocara'' is an extinct genus of mastodonsauroid temnospondyl. The type species is ''Selenocara groenlandica'', described by Gunnar Säve-Söderbergh in 1935 on the basis of skull bones from the Lower Triassic Wordie Creek Formation of Greenland. Säve-Söderbergh originally described it as a new species of ''Wetlugasaurus''. The original material was redescribed in 1997 by Hans C. Bjerring, who transferred ''Wetlugasaurus groenlandicus'' to the separate genus named ''Selenocara''. Bjerring listed the quadrate condyles which were about level with the occipital condyles (both transversally and horizontally), the orbitofacial openings wholly visible through the orbitopalatine openings when viewed ventrally, and the long axes of each orbitofacial opening directed toward the ipsilateral auditive incisure as the characters justifying the exclusion of ''S. groenlandica'' from the genus ''Wetlugasaurus''. Bjerring stated that the generic name is derived from the Greek words ''se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
