Watsonisuchus is an extinct genus of temnospondyl amphibian from the Early Triassic of Australia, Madagascar, and South Africa. [1] It was up to 122 cm long and had a robust skull of 24 cm in length. [2]

A genus is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.

Amphibian A class of ectothermic tetrapods, which typically breed in water

Amphibians are ectothermic, tetrapod vertebrates of the class Amphibia. Modern amphibians are all Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decline in amphibian populations for many species around the globe.

Early Triassic first of three epochs of the Triassic period of the geologic timescale

The Early Triassic is the first of three epochs of the Triassic Period of the geologic timescale. It spans the time between 251.902 Ma and 247.2 Ma. Rocks from this epoch are collectively known as the Lower Triassic, which is a unit in chronostratigraphy. The Early Triassic is the oldest epoch of the Mesozoic Era and is divided into the Induan and Olenekian ages.

Chiniquodon is an extinct genus of carnivorous cynodonts, which lived during the Late Triassic (Carnian) in South America and Africa. Chiniquodon is closely related to a contemporary genus, Probelesodon, and close to the ancestry of mammals.

<i>Azendohsaurus</i> genus of reptiles

Azendohsaurus is a genus of extinct, herbivorous archosauromorph from the Late Triassic Period of Morocco. The type species is known only from a partial jaw fragment from Morocco. Azendohsaurus used to be regarded as a dinosaur, as either an ornithischian or a prosauropod. New research suggests that Azendohsaurus is not a dinosaur at all, but a non-archosauriform archosauromorph that independently evolved many craniodental characters similar to herbivorous dinosaurs.

Triadobatrachus is an extinct genus of salientian frog-like amphibians, including only one known species, Triadobatrachus massinoti. It is the oldest member of the frog lineage known, and an excellent example of a transitional fossil. It lived during the Early Triassic about 250 million years ago, in what is now Madagascar.

<i>Thadeosaurus</i> genus of tetrapods that developed two holes (temporal fenestra) in each side of their skulls, about 300 million years ago

Thadeosaurus is an extinct genus of diapsid reptile belonging to the family Younginidae. Fossils have been found in the Lower Sakamena Formation of the Morondava Basin, Madagascar in 1981, and date to the late Permian to the early Triassic period.

<i>Hovasaurus</i> genus of reptiles

Hovasaurus is an extinct genus of diapsid reptile belonging to the Order Eosuchia. It lived in what is now Madagascar during the Late Permian and Early Triassic, being a survivor of the Permian–Triassic extinction event and the geologically youngest member of the Tangasauridae.

<i>Wetlugasaurus</i> genus of reptiles (fossil)

Trematosauridae family of amphibians (fossil)

Trematosauridae are a family of large temnospondyl amphibians with many members. They first appeared during the Olenekian stage 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.

<i>Wantzosaurus</i> genus of amphibians (fossil)

Wantzosaurus was a genus of temnospondyl amphibian of the Trematosauridae family. It existed during the Early Triassic in what is now Madagascar. It showed adaptations for an almost completely aquatic lifestyle, having the ability to swim by lateral undulation.

Almasaurus is an extinct genus of trematosaurian temnospondyl within the family Latiscopidae. It is known from several skulls and some postcranial material found from the Argana Formation in Morocco, which dates back to the Late Triassic.

<i>Mahavisaurus</i> genus of amphibians (fossil)

Mahavisaurus is an extinct genus of rhytidosteid temnospondyl from the early Triassic period of Iraro, Madagascar. It is known from the holotype MNHN MAE 3037, a nearly complete skull, recovered from the Middle Sakamena Formation. This genus was named by J. P. Lehman in 1966, and the type species is Mahavisaurus dentatus.

<i>Thoosuchus</i> genus of amphibians

Thoosuchus 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. 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.

Tertremoides is an extinct genus of trematosaurian temnospondyl within the family Trematosauridae from Madagascar. It was first named by Lehman, J-P. in 1966 as Trematosaurus madagascariensis but renamed to Tertremoides ambilobensis by Lehman in 1979. Its closest relative was Trematolestes.

Tangasauridae family of tetrapods that developed two holes (temporal fenestra) in each side of their skulls, about 300 million years ago

Tangasauridae is a family of eosuchian diapsids. Specimens have been found that are of Late Permian to Early Triassic in age from the Sakamena Group of western Madagascar. They lived alongside other taxa present from the Sakamena Group, including temnospondyls, rhynchosaurs, and gomphodont eucynodonts. Fossils have been found of numerous specimens of common members of this family such as Hovasaurus and Thadeosaurus in different stages of ontogenic development. Recent material from the Middle Sakamena Formation of the Morondava Basin of Madagascar that dates back to the early Triassic period suggests that the Tangasauridae were relatively unaffected by the Permian-Triassic extinction event.

<i>Isalorhynchus</i> genus of reptiles

Isalorhynchus is an extinct genus of hyperodapedontine rhynchosaur from the late Triassic period of Toliara Province, southwestern Madagascar. It is known from the holotype MDE-R18, a nearly complete maxilla and from other specimens from the same locality, Malio River area. It was found in the Makay Formation of the Morondava Basin. It was first named by Eric Buffetaut in 1983 and the type species is Isalorhynchus genovefae. The majority of Isalorhynchus specimens are isolated jaw bones, but two nearly complete skeletons were found in 1998. Langer et al., 2000 concluded that Isalorhynchus is a synonym of Hyperodepedon and referred it to a new species of Hyperodepedon. Whatley, 2005 retained this genus as valid with a description of new materials in her PhD thesis. Montefeltro et al., 2010 and Langer et al., 2010 accepted Isalorhynchus as valid genus.
