Chomatobatrachus is a genus of prehistoric temnospondyl from the Triassic.
A temnospondyl species placed in a monotypic genus Chomatobatrachus and allied to the Lydekkerinidae family. The description was published in 1974 by the palaeontologist John W. Cosgriff. [1] [2] The type locality is Meadowbank, a site associated with the Knocklofty Formation, where a skull was discovered in Induan terrestrial mudstone. [3]
Deltasaurus kimberleyensis was a temnospondyl amphibian of the family Rhytidosteidae that existed during the Carnian stage of the Triassic. The fossilised remains were discovered in the Blina Shale formation in the Kimberley region of northwest Australia in 1965.
Cherninia is an extinct genus of mastodonsaurid temnospondyl. The type species, Cherninia denwai, is known from the Denwa Formation of India. It is based on a massive skull, ISI A 54, which was originally considered a species of Parotosuchus in 1998 before being given its own genus in 2001.
Deltasaurus is an extinct genus of Carnian temnospondyl amphibian of the family Rhytidosteidae.
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. The type genus is Lydekkerina, the namesake of the family and the best-known lydekkerinid.
Rhytidosteoidea is a superfamily of Temnospondyli, early amphibian species that existed during the Carboniferous, Permian, and Triassic periods. The taxon was established in 1965 to accommodate two new species of Deltasaurus, the author recognising an alliance with previously described genera.
Deltasaurus pustulatus is an amphibian fossil species of the family Rhytidosteidae. The temnospondyl hunted invertebrates and fish during the late stage Triassic epoch, and somewhat resembles the only other species of the eastern Gondwanan genus Deltasaurus. The only known evidence of the species was discovered in a drill core in Southwest Australia, near Geraldton, a seemingly improbable event that produced the only known example of Triassic vertebrate fauna in the ecologically exceptional region's Kockatea Formation.
Arcadia is an extinct genus of temnospondyl amphibians in the family Rhytidosteidae from the early Triassic. The remains were found in and named after the Arcadia Formation of Australia.
Angusaurus is an extinct genus of trematosaurian temnospondyl within the family Trematosauridae.
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.
Banksiops is an extinct genus of temnospondyl amphibian in the family Brachyopidae, recovered from Tasmania.
Cryobatrachus is an extinct genus of temnospondyl amphibian from the Early Triassic of Antarctica. The type species is Cryobatrachus kitchingi. It is known from a partial skull and an imprint of the skull roof, both found in the Fremouw Formation of the Transantarctic Mountains at about 85° south latitude and described in 1974. Many small bone fragments have also been identified, although they cannot be attributed with certainty to C. kitchingi. Cryobatrachus has been classified in the family Lydekkerinidae, as it is similar in appearance to the genus Lydekkerina from South Africa. Because only a small number of features distinguish it from other lydekkerinids, Cryobatrachus kitchingi has more recently been considered a nomen dubium, meaning that its distinction from other better-known species may be unwarranted.
Notobrachyops is a genus of brachyopid temnospondyl amphibian. It is known from a skull roof impression found in the Ashfield Shale of Mortdale, New South Wales, Australia. The Ashfield Shale has also yielded a shark species, a lungfish species, six species of paleoniscid fish, a species of holostean fish, a subholostean fish, and the labyrinthodont amphibian Paracyclotosaurus davidi.
Rotaurisaurus is an extinct genus of temnospondyls from the family Lapillopsidae. This genus is known only from an incomplete crushed skull and associated left jaw, together given the designation UTGD 87795. The generic name, Rotaurisaurus, is a combination of Latin words translating to "circle-eared lizard". This references the shape of its otic notches, which acquire a circular form due to being partially enclosed by the tabular bones at the back of the skull. The specific name, contundo, references the specimen's poor level of preservation, as it is derived from the Latin word for "squashed".
Rileymillerus is an extinct genus of temnospondyl amphibian from the Late Triassic Post Quarry in the Dockum Group of Texas that was described by John Bolt and Sankar Chatterjee in 2000. The holotype, a nearly complete skull with articulated jaws, is housed at the Museum of Texas Tech University. The genus is named for Riley Miller, who allowed Chatterjee to work on the Post Quarry, and the species is named for the paleontologist John Cosgriff.
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.
The Popo Agie Formation is a Triassic geologic formation that crops out in western Wyoming, western Colorado, and Utah. It was deposited during the Late Triassic in fluvial (river) and lacustrine (lake) environments that existed across much of what is now the American southwest. Fragmentary fossils of prehistoric reptiles and amphibians, including pseudosuchian reptiles and temnospondyl amphibians, have been discovered in the Popo Agie Formation. Dinosaur remains are also among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.
Pneumatostega is an extinct genus of rhytidosteid temnospondyl from the early Triassic period of Cape Province of South Africa. It is known from the holotype BPI F981, a dorsal mould of a skull roof and from the referred specimen SAM 11188, partial skull fragments and postcranial remains recovered from the Lystrosaurus Assemblage Zone in the Beaufort Group near Middelburg. This genus was named by J. W. Cosgriff and J. M. Zawiskie in 1979, and the type species is Pneumatostega potamia.
Eolydekkerina is an extinct genus of temnospondyl from the Early Triassic of South Africa. It belongs to the family Lydekkerinidae, along with the closely related genus Lydekkerina. It is known from a single type species, Eolydekkerina magna, which was named in 1996 from a part of the Beaufort Group called the Lystrosaurus Assemblage Zone.
Latiscopus disjunctus is a small Late Triassic temnospondyl collected in 1940 by a Works Projects Administration crew working near Otis Chalk, Texas that was described by John Wilson in 1948.
The Knocklofty Formation is an Early Triassic geologic formation from southern Tasmania, Australia, belonging to the Induan stage. It is made of Sandstone.
