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. Phylogeny ''Qantas'' in a cladogram A cladogram (from Greek ''clados'' "branch" and ''gramma'' "character") is a diagram used in cladistics to show relations among organisms.

Benthosuchidae
''Benthosuchus'' (meaning "deep water crocodile") is an extinct genus of temnospondyl amphibian from the Early Triassic of Russia. It was primarily aquatic, living in rivers and lakes. Multiple species are known, with the largest reaching about 2.5 meters in length. Russian paleontologist Ivan Yefremov fremovcalled the genus ''Benthosaurus'' "deep water lizard" (from Ancient Greek βένθος (''benthos'') "depth, deep water") in his original 1929 description, "in view of its clearly indicated adaptation to life in deep water" shown by "the position of the orbits and the flatness of the skull." The type species ''B. sushkini'' honored his late teacher Petr Sushkin. The generic name was preoccupied by ''Benthosaurus'' Goode & Bean, 1886, a fish, and he renamed the genus ''Benthosuchus'' ("deep water crocodile") in 1937.Efremov, I. A. (1929).

Trematosaurus
''Trematosaurus'' is an extinct genus of trematosaurid temnospondyl amphibian found in Germany and Russia. It was first named by Hermann Burmeister in 1849 and the type species is ''Trematosaurus brauni''. History of study ''Trematosaurus'' was one of the first temnospondyls to be described. The type locality, called Merkel's Quarry, is in east-central Germany at Bernburg an der Saale within the Bausandstein (Olenekian) and was collected for several decades from the 1840s into the early 20th century, producing extensive cranial remains, although the majority of these are preserved as internal molds (steinkerns) or natural molds. The name ''Trematosaurus'' was in fact coined in 1842 by Carl von Braun, a frequent collector who used the Greek suffix ''trema'' ('hole') in reference to the pineal foramen to form the generic epithet, but as he provided no formal description, the name was not considered valid until the work of Burmeister, who named the type species after Braun.

Thoosuchus
''Thoosuchus'' (meaning "active crocodile") is an extinct genus of basal trematosauroid trematosaurian temnospondyl. Fossils have been found from Russia and date back to the Early Triassic. It is the type genus of the family Thoosuchidae, formerly called the subfamily Thoosuchinae and placed within Benthosuchidae. Efremov, I. A. (1940). Preliminary description of the new Permian and Triassic Tetrapoda from U.S.S.R. ''Trudy Paleontologicheskogo Instituta'' 10:1–140. The benthosuchids were originally composed of the majority of basal trematosaurian forms regarded as the ancestors of the trematosaurids. Although the genus was first named in 1940, material from one species, ''E. yakovlevi'', was originally tentatively referred to ''Trematosuchus'' in 1926. For its family, ''Thoosuchus'' was fairly small, reaching a little over 60 cm with a 15 cm skull. ''Thoosuchus'' superficially resembles the more derived trematosaurids, but can be distinguished from them on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
