Mahavisaurus is an extinct genus of rhytidosteid temnospondyl from the early Triassic period (Induan stage) 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. [1]
The Alytidae are a family of primitive frogs. Their common name is painted frogs or midwife toads. Most are endemic to Europe, but three species occur in northwest Africa, and a species formerly thought to be extinct is found in Israel.
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.
Pholiderpeton is an extinct genus of embolomere amphibian which lived in the Late Carboniferous period (Bashkirian) of England. The genus was first named by Thomas Henry Huxley in 1869 to include the species P. scutigerum, based on the disarticulated front half of a skeleton discovered near Bradford, Yorkshire. Associated fossil wood suggests that this specimen died inside a Lepidodendron tree trunk.
Piveteauia is an extinct genus of prehistoric coelacanth fish which lived during the Lower Triassic period. The type specimen was discovered in the Middle Sakamena Group in northwestern Madagascar by French paleoichthyologist Jean-Pierre Lehman.
Arganasaurus is an extinct genus of prehistoric temnospondyl amphibian belonging to the family Metoposauridae that lived in Morocco during the Late Triassic (Carnian).
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.
Batrachosuchoides is an extinct genus of prehistoric amphibian from the Early Triassic of Russia. It was found in the Baskunchakskaia Series and the Lestanshorskaya Svita.
Chomatobatrachus is a genus of prehistoric temnospondyl from the Triassic.
Deltacephalus is an extinct genus of prehistoric stereospondyl temnospondyl from Madagascar.
Indobrachyops is an extinct genus of temnospondyl amphibian from the Early Triassic of India. It is known from a nearly complete fossil skull that was first described by paleontologists Friedrich von Huene and M. R. Sahni in 1958 from the Panchet Formation in Raniganj Coalfield. Indobrachyops belongs to a group of mostly semi-aquatic temnospondyls called Stereospondyli, but its exact placement within the group has been uncertain since its first description.
Cosgriffius is an extinct genus of trematosaurian temnospondyl within the family Trematosauridae. It was described in 1993 by Samuel P. Welles based on a single partial skull from the well-known Meteor Crater Quarry in Arizona that also produced more abundant remains of the capitosaur Wellesaurus peabodyi. The skull was long and slender, features typically associated with the trematosaurid subfamily Lonchorhynchinae. This is the only trematosaurid known from western North America.
Lyrocephaliscus is an extinct genus of trematosaurian temnospondyl within the family Trematosauridae.
Wellesaurus is an extinct genus of mastodonsauroid temnospondyl. They were amphibious carnivores that lived in freshwater environments.
Platystega is an extinct genus of trematosaurian temnospondyl within the family Trematosauridae.
Trematosuchus is an extinct genus of trematosaurian temnospondyl within the family Trematosauridae from South Africa. It was first named by Haughton in 1915 as Trematosaurus sobeyi. It was assigned to its own genus Trematosuchus by Watson in 1919.
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.
Paul Schultz Martin was an American geoscientist at the University of Arizona who developed the theory that the Pleistocene extinction of large mammals worldwide was caused by overhunting by humans. Martin's work bridged the fields of ecology, anthropology, geosciences, and paleontology.
Edingerella is an extinct genus of temnospondyl amphibian from the Early Triassic of Madagascar. It is a basal capitosaur closely related to Watsonisuchus.
Parasemionotiformes is an extinct order of neopterygian ray-finned fish that existed globally during the Triassic period. It comprises the families Parasemionotidae and Promecosominidae. Many of the included genera are monotypic and most species lived during the Early Triassic epoch.
