Platycepsion wilksoni is an extinct species of prehistoric amphibian, known from partial skeleton deposited in shale at the Gosford Quarry site of the Terrigal Formation in Australia.
The species is assigned to a currently monotypic genus, the synonym Platyceps wilkinsonii, a name published in 1887 by the Australian palaeontologist William Stephens, was nominated as the type. A revision in 1964 by Oskar Kuhn assigned the species to the genus Platycepsion to replace the earlier combination, which was invalidated by an earlier use of the name Platyceps for a colubrid genus of snakes. Another revising author John W. Cosgriff named the species as the type for a new genus, Blinasaurus, [3] unaware of Kuhn's replacement of the name, and placed a second species in the same genus, later separated to a new combination as Batrachosuchus henwoodi .

The author noted the epithet Wilkinsonii in the first description as commemorating the deputy chair of the Linnean Society of New South Wales, C. S. Wilkinson. [2]
Hardwicke's rat snake, also known commonly as the glossy-bellied racer, Gray's rat snake, and the spotted bellied snake, is a species of snake in the family Colubridae. The species is native to Asia. There are three recognized subspecies.
Meiolania is an extinct genus of meiolaniid stem-turtle native to Australasia from the Middle Miocene to Late Pleistocene and possibly Holocene. It is best known from fossils found on Lord Howe Island, though fossils are known from mainland Australia, New Caledonia, and possibly Vanuatu and Fiji.
Charles Smith Wilkinson was an Australian geologist. He became geological surveyor in charge in New South Wales in 1875 and was president of the Royal Society of New South Wales in 1887.
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.
Brachalletes was an early marsupial from the Pleistocene deposits of Australia. Its relationship with other marsupial species is under debate. The genus is extinct. The species was assigned to the order Diprotodontia, suborder Macropodiformes, and family Hypsiprymnodontidae by McKenna and Bell in 1997, though it is placed in its own order by other authorities. The species is described as an active carnivore.
Deltasaurus is an extinct genus of Carnian temnospondyl amphibian of the family Rhytidosteidae.
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.
Bothriceps is an extinct genus of stereospondyl temnospondyl. It is a member of the infraorder Trematosauria and is the most basal brachyopomorph known. It is one of the only brachyopomorph that lies outside the superfamily Brachyopoidea, which includes the families Brachyopidae and Chigutisauridae. It shares several similarities to Keratobrachyops, another basal brachyopomorph, and may be closely related to or even synonymous with it.
Blinasaurus is a name of an extinct genus of prehistoric brachyopid found in Triassic geological formations of Australia. The type species is Platyceps wilkinsonii Stephens, 1887. The genus was established by John W. Cosgriff in 1969 to incorporate the type, discovered in New South Wales, and the author's new fossil species, Blinasaurus henwoodi, describing type material found in Blina Shale in the Kimberley region of northwest Australia.
Banksiops is an extinct genus of temnospondyl amphibian in the family Brachyopidae, recovered from Tasmania.
Chomatobatrachus is a genus of prehistoric temnospondyl from the Triassic.
Erythrobatrachus is an extinct genus of trematosaurian temnospondyl within the family Trematosauridae. The sole species Erythrobatrachus noonkanbahensis was separated to a monotypic genus, distinguishing it from related taxa when the description was published in 1972. The type material was a matrix cast revealing the impression of several fragments of skull excavated at the Blina Shale formation in the northwest of the Australian continent. The genus name is derived from ancient Greek, combining terms for red, erythro, with frog, batrachos, to describe the iron staining of the fossilised amphibian specimens. The type location described by the specific epithet was Noonkanbah Station.
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 amphibian-grade tetrapod 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".
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.
Platyceps is a genus of snakes of the family Colubridae endemic to Eurasia.
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.
Blina Shale is a fossil bearing geological formation located in the Kimberley region of Northwest Australia. The location is rich in deposits of vertebrate material, and the site of previously unknown Triassic species. Flora and invertebrate species have also been identified in the deposits, including microplankton and microflora.
Batrachosuchus henwoodi is a fossil species of amphibian, first described as Blinasaurus henwoodi by John W. Cosgriff in 1969. The species was placed in a new generic combination when separating the genus Blinasaurus, currently subsumed as a synonym to the genus Platycepsion.
Macropus pan is a species of marsupial that existed during the Pliocene in Australia, known only from fossils located at several sites across Australia. The species is recognised as allied to the modern grey kangaroos, the western Macropus fuliginosus and eastern Macropus giganteus, in a clade initially named as subgenus Macropus (Macropus) Dawson & Flannery. The first description was provided by Charles W. De Vis in 1895, emerging from the author's examination of fossil material held at the Queensland Museum. Fossil specimens of Quanbun local fauna, named for a site in Western Australia, were also identified as this species. The origin of the type specimen was not recorded, although based on comparisons to material with a known provenance it is assumed to have excavated at Chinchilla, Queensland. A larger macropod than any modern species, the standing height was estimated to be over two metres.
