Stereospondyls
The Stereospondyli are a group of extinct Temnospondyli, temnospondyl amphibians that existed primarily during the Mesozoic period. They are known from all seven continents and were common components of many Triassic ecosystems, likely filling a similar ecological niche to modern crocodilians prior to the diversification of pseudosuchian archosaurs. Classification and anatomy The group was first defined by Zittel (1888) on the recognition of the distinctive vertebral anatomy of the best known stereospondyls of the time, such as ''Mastodonsaurus'' and ''Metoposaurus''. The term 'stereospondylous' as a descriptor of vertebral anatomy was coined the following year by Fraas, referring to a vertebral position consisting largely or entirely of the intercentrum in addition to the neural arch. While the name 'Stereospondyli' is derived from the stereospondylous vertebral condition, there is a diversity of vertebral morphologies among stereospondyls, including the diplospondylous ('Tupil ...

Mastodonsaurus
''Mastodonsaurus'' (meaning "teat tooth lizard") is an extinct genus of temnospondyl amphibian from the Middle Triassic of Europe. It belongs to a Triassic group of temnospondyls called Capitosauria, characterized by their large body size and presumably aquatic lifestyles. ''Mastodonsaurus'' remains one of the largest amphibians known, and may have exceeded 6 meters (20 feet) in length. Description Like those of many other capitosaurs, the head of ''Mastodonsaurus'' was triangular, reaching about in the largest specimens. Narrow grooves on the surface of the skull bones called sulci show it had sensory organs that could detect vibrations and pressure under water, similar to the lateral lines on fish. The large, oval eye sockets are midway along the skull with the nostrils near the tip of the snout. Small ear holes (otic notches) are indented on either side of the back of the skull. The upper surface of the skull bones of ''Mastodonsaurus'' bore an intricate pattern of pits an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lapillopsidae is a family of Temnospondyli Temnospondyli (from Greek τέμνειν, ''temnein'' 'to cut' and σπόνδυλος, ''spondylos'' 'vertebra') is a diverse order of small to giant tetrapods—often considered primitive amphibians—that flourished worldwide during the Carb .... ''Lapillopsis'' was found as the sister to ''Rotaurisaurus'' in a 1999 analysis that found the Lapillopsidae as basal stereospondyls.

Rhinesuchidae
Rhinesuchidae is a family of tetrapods that lived primarily in the Permian period. They belonged to the broad group Temnospondyli, a successful and diverse collection of semiaquatic tetrapods which modern amphibians are probably descended from. Rhinesuchids can be differentiated from other temnospondyls by details of their skulls, most notably the interior structure of their otic notches at the back of the skull. They were among the earliest-diverging members of the Stereospondyli, a subgroup of temnospondyls with flat heads and aquatic habits. Although more advanced stereospondyls evolved to reach worldwide distribution in the Triassic period, rhinesuchids primarily lived in the high-latitude environments of Gondwana (what is now South America and Africa) during the Guadalupian and Lopingian epochs of the Permian. The taxonomy of this family has been convoluted, with more than twenty species having been named in the past; a 2017 review recognized only eight of them (distributed a ...

Lydekkerinidae
Lydekkerinidae is a family of stereospondyl temnospondyls that lived in the Early Triassic period. During this time period, lydekkerinids were widely distributed, with putative remains reported from Russia, Greenland, India, South Africa, Madagascar, Australia, and Antarctica. In contrast to most other stereospondyls, lydekkerinids were relatively small-bodied (most with skulls less than 10 cm in length). The type genus is ''Lydekkerina'', the namesake of the family and the best-known lydekkerinid. Description The identification of features shared among lydekkerinids (synapomorphies) necessarily varies depending on which taxa are considered to belong to this group (see further in next section). In the most expansive concept, the family includes the eponymous ''Lydekkerina'' (and junior synonyms like '''Broomulus''' and '''Limnoiketes'''), ''Eolydekkerina'' from South Africa, ''Deltacephalus'' from Madagascar, ''Luzocephalus'' from Russia and Greenland (which includes the '''Aqui ...

Stereospondylomorpha
Stereospondylomorpha is a clade of temnospondyls. It includes the superfamily Archegosauroidea and the more diverse group Stereospondyli. Stereospondylomorpha was first proposed by Yates and Warren (2000), who found Archegosauroidea and Stereospondyli to be sister taxa in their phylogenetic analysis. A similar clade is Archegosauriformes, named by Schoch and Milner (2000), which includes Stereospondyli and some Permian temnospondyls that are similar in appearance to stereospondyls, including the archegosauroids. However, according to Schoch and Milner's phylogeny, Archegosauroidea is a paraphyletic group of taxa that are successively basal to Stereospondyli, rather than a monophyletic sister taxon. ''Chinlestegophis'', a putative Triassic stereospondyl considered to be related to metoposauroids such as ''Rileymillerus'', has been noted to share many features with caecilian Caecilians (; ) are a group of limbless, vermiform or serpentine amphibians.

Broomistega Putterilli
''Broomistega'' is an extinct genus of temnospondyl amphibian in the family Rhinesuchidae. It is known from one species, ''Broomistega putterilli'', which was renamed in 2000 from ''Lydekkerina putterilli'' Broom 1930. Fossils are known from the Early Triassic ''Lystrosaurus'' Assemblage Zone of the Beaufort Group in the Karoo Basin of present-day South Africa, a region that had been an enclave of Gondwana. Specimens of ''B. putterilli'' were once thought to represent young individuals of another larger rhinesuchid such as ''Uranocentrodon'', but the species is now regarded as a paedomorphic taxon, possessing the features of juvenile rhinesuchids into adulthood. In 2013, a well-preserved skeleton of ''Broomistega'' was discovered alongside the skeleton of the cynodont ''Thrinaxodon'' (a mammal relative) in a cast of a burrow. The individual probably entered the burrow while the cynodont was in a state of aestivation (dormancy), and afterwards a flash flood filled the burrow wit ...

Peltobatrachus Pustulatus
''Peltobatrachus'' (from Greek ''pelte'', meaning shield and batrakhos, meaning frog) is an extinct genus of temnospondyl amphibian from the late Permian period of Tanzania. The sole species, ''Peltobatrachus pustulatus'', is also the sole member of the family Peltobatrachidae. Description ''Peltobatrachus'' was a large, slow moving animal, up to in length. It was a fully terrestrial amphibian, only returning to the water to lay its eggs. To protect itself against predators such as the large gorgonopsid therapsids, it had developed an armadillo-like armored plating covering its body and tail. The armor consisted of broad plates on the shoulders and hips and narrower plates on the rest of the body. Although no teeth of the creature have been found, it probably fed on insects, worms, and snail A snail is, in loose terms, a shelled gastropod. The name is most often applied to land snails, terrestrial pulmonate gastropod molluscs. However, the common name ''snail'' ...

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 ...
