Neoceratodus is a genus of lungfish in the family Neoceratodontidae. The extant Australian lungfish is the only surviving member of this genus, but it was formerly much more widespread, being distributed throughout Africa, Australia, and South America. Species were also much more diverse in body plan; for example, the Cretaceous species Neoceratodus africanus was a gigantic species that coexisted with Spinosaurus in what is now the Kem Kem Formation of Morocco. The earliest fossils from this genus are of Neoceratodus potkooroki from the mid Cretaceous (Albian-Cenomanian) Griman Creek Formation of Australia; remains from the Late Jurassic of Uruguay assigned to this genus probably do not belong to the genus.
The South Polar region of the Cretaceous comprised the continent of East Gondwana–modern day Australia, Zealandia, and Antarctica–a product of the break-up of Gondwana in the Cretaceous Period. The southern region, during this time, was much warmer than it is today, ranging from perhaps 4–8 °C (39–46 °F) in the latest Cretaceous Maastrichtian in what is now southeastern Australia. This prevented permanent ice sheets from developing and fostered polar forests, which were largely dominated by conifers, cycads, and ferns, and relied on a temperate climate and heavy rainfall. Major fossil-bearing geological formations that record this area are: the Santa Marta and Sobral Formations of Seymour Island off the Antarctic Peninsula; the Snow Hill Island, Lopez de Bertodano, and the Hidden Lake Formations on James Ross Island also off the Antarctic Peninsula; and the Eumeralla and Wonthaggi Formations in Australia.
Aphaneramma is an extinct genus of marine temnospondyl amphibian. It lived during the Early Triassic epoch, approximately 252–247 Ma ago, and had a global distribution.
Cladophlebis is an extinct form genus of fern, used to refer to Paleozoic and Mesozoic fern leaves that have "fern fronds with pinnules that are attached to the rachis, and have a median vein that runs to the apex of the pinnule, and veins from that are curved and dichotomise". By convention this genus is not used to refer to fossil ferns from the Cenozoic. Ferns with this morphology belong to several families, including Osmundaceae, Dicksoniaceae and Schizaeaceae. Ferns with this morphology are common during the Paleozoic and Mesozoic in both the northern and southern hemispheres.
Siderops is an extinct genus of chigutisaurid temnospondyl from Early Jurassic of Australia, containing the species S. kehli.
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.
Austropelor is an extinct genus of possible chigutisaurid temnospondyl from the Early Jurassic of Australia. Fossil remains were found in the Marburg Sandstone 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.
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.
Lydekkerina is an extinct genus of stereospondyl temnospondyl. It is the type genus of the family Lydekkerinidae. Fossils have been collected from Early Triassic deposits in South Africa and Australia. The type species is L. huxleyi, first described in 1889. While most other stereospondyls were semiaquatic, Lydekkerina was exclusively terrestrial.
Keratobrachyops is an extinct genus of trematosaurian temnospondyl found in the Arcadia Formation of Queensland, Australia. It had been thought to be a basal chigutisaurid but is now thought to be a basal brachyopomorph closely related to the genus Bothriceps, and may even be a synonym of it.
Kourerpeton is an extinct genus of dvinosaurian temnospondyl. Fossils of Kourerpeton were discovered in a window of a barber's shop in either Bisbee or Mesa, Arizona. Kourerpeton was named in 1976, with the type and only species being K. bradyi. It was originally assigned to the monotypic family Kourerpetidae, which has been alternatively spelled Kourerpetontidae.
Rewana is an extinct genus of prehistoric temnospondyls. Two species have been described from the Arcadia Formation of Australia.
Amblydactylus is an ichnogenus that has been attributed to dinosaurs. The generic name, derived from the Greek words amblys and dáktylos, means "dull finger". Two species of Amlydactylus have been named: A. gethingi, which references the Gething Formation where it was found; and A. kortmeyeri, which honours Carl Kortmeyer who discovered the holotype.
Wintonopus is an ichnogenus of dinosaur footprint. Its footprints have been found at Lark Quarry in Queensland Australia. The genus is named after the Winton Formation in which the tracks were found. Other tracks were found in the Broome Sandstone of Dampier Peninsula, Western Australia.
Qantas is a genus of trematosauroid temnospondyl from the Early Triassic. Fossils have been found from the Kamennyi Yar Formation in Borsky District, Samara Oblast. The type species Qantas samarensis was named in 2012 and placed in the family Benthosuchidae, as it was viewed as a close relative of Benthosuchus. The subfamily Qantasinae was established to include Qantas, and possibly the genus Tirraturhinus. Qantas is named after the Australian airline Qantas, which supported the original study of the fossils.
Genevievella is a genus of trilobites with a short inverted egg-shaped outline, a wide headshield, small eyes, and long genal spines. The backrim of the headshield is inflated and overhangs the first of the 9 thorax segments. The 8th thorax segment from the front bears a backward directed spine that reaches beyond the back end of the exoskeleton. It has an almost oval tailshield with 5 pairs of pleural furrows. It lived during the Upper Cambrian in what are today Canada and the United States.
The Evergreen Formation is a Pliensbachian to Toarcian geologic formation of the Surat Basin in New South Wales and Queensland, eastern Australia. Traditionally it has been considered to be a unit whose age has been calculated in between the Pliensbachian and Toarcian stages of the Early Jurassic, with some layers suggested to reach the Aalenian stage of the Middle Jurassic, yet modern data has found that an Early Pliensbachian to Latest Toarcian age is more possible. The formation was named due to the "Evergreen Shales", defined with a lower unit, the Boxvale Sandstone, and a partially coeval, partially younger upper unit, the Westgrove Ironstone Member. This unit overlies the Hettangian-Sinemurian Precipice Sandstone, as well several informal units such as the Nogo Beds, and Narayen beds, as well Torsdale Volcanics. This unit likely was deposited in a massive lacustrine body with possible marine environment influences.
Eomurruna is a genus of procolophonid reptile that existed in what is now Queensland, Australia during the Early Triassic period. The genus is made up of a single species, E. yurrgensis, originally uncovered within the Arcadia Formation in 1985. Since then over 40 specimens have been referred to the genus, making Eomurruna one of the most complete organisms so far found from the Mesozoic of Australia.
Kudnu is an extinct genus of neodiapsid reptile from the Early Triassic Arcadia Formation of Australia. The type species is K. mackinlayi.
