Koolasuchus is an extinct genus of brachyopoid temnospondyl in the family Chigutisauridae. Fossils have been found from Victoria, Australia and date back 120 Ma to the Aptian stage of the Early Cretaceous. Koolasuchus is the youngest known temnospondyl. Koolasuchus is known from several fragments of the skull and other bones such as vertebrae, ribs, and pectoral elements. The type species Koolasuchus cleelandi was named in 1997. Koolasuchus cleelandi was adopted as the fossil emblem for the state of Victoria, Australia on 13 January 2022.
Apsopelix is an extinct genus of ray-finned fish that existed about 95-80 million years ago in the shallow waters of the Western Interior Seaway, Hudson Seaway, England, France, and Japan.
Dinosaur Dreaming is a paleontological site situated near Inverloch, Victoria, Australia. Remains of primitive mammals from the Cretaceous Age were first uncovered there in 1997 by researchers from Museum Victoria and the Monash University Science Centre.
Siamamia is an extinct genus of ray-finned fish from Northeasthern Thailand. They belong to family Amiidae and are halecomorph fishes endemic to Early Cretaceous freshwater environments in eastern Asia.
Victalimulus mcqueeni is an extinct horseshoe crab, from Early Cretaceous (Aptian) Koonwarra Fossil Beds in eastern Victoria, Australia. The holotype and only known specimen was discovered by James McQueen who was encouraged by Leon Costermans to take it to the Museum of Victoria. Unlike modern species of horseshoe crab, it was likely native to freshwater as the Koonwarra Fossil Beds was, during the Aptian epoch, a freshwater lake.
Spathiurus is an extinct genus of prehistoric ray-finned fish that lived during the Cenomanian in the Sannine Formation of Lebanon.
Prymnetes is an extinct genus of prehistoric bony fish that lived during the Late Cretaceous epoch.
Mesoclupea showchangensis is an extinct ichthyodectiform ray-finned fish that lived in freshwater environments in what is now China during the Early Cretaceous epoch. It differs from its sister genus, Chuhsiungichthys, primarily by having a more posteriorly-placed dorsal fin.
Aetheolepis is an extinct genus of ray-finned fish which lived in freshwater environments in what is now Western Australia and New South Wales during the Jurassic period. It contains one species, A. mirabilis. Aetheolepis was previously thought to be an archaeomaenid, until a 2016 study instead recovered it as a member of the family Dapediidae. Like other dapediids, it had a deep, discoid-shaped body. Fossils of A. mirabilis have been found in the Talbragar River fossil beds of New South Wales and the Colalura Sandstone of Western Australia. It was named by Arthur Smith Woodward in 1865 along with other Talbragar fish.
Stichopterus is an extinct genus of chondrostean ray-finned fish that lived during the Early Cretaceous epoch in Asia. It has been found in Russia and Mongolia.
Mioceratodus is an extinct genus of lungfish in the family Neoceratodontidae, which also contains the extant Queensland lungfish. It is known only from Oligocene and Miocene-aged sediments in Australia, although phylogenetic evidence supports it having first diverged from its closest relative, Neoceratodus, during the Late Jurassic or Early Cretaceous period.
Metaceratodus is an extinct genus of prehistoric lungfish in the family Ceratodontidae, with an indeterminate specimen known from the Late Triassic (Norian)-aged Lissauer Breccia of Poland and more complete specimens known from the Late Cretaceous of Queensland, Australia and Argentina. The genus was named and described by Frederick Chapman in 1914.
Amiopsis is an extinct genus of prehistoric bony fish belonging to the family Amiidae. Fossils are known from the Late Jurassic Solnhofen Limestone, Germany, the Early Cretaceous Purbeck Group, England, La Pedrera de Rúbies Formation, Spain and Bernnissant Iguanodon locality, Belgium and the Late Cretaceous (Cenomanian) of the Balkans. The monophyly of the genus is questionable, due to it being based on a single character, "the presence of three or more lateral fossae on each side of most abdominal centra". Remains previously assigned to this genus from the Early Cretaceous Las Hoyas, Spain have been moved into the new genus Hispanamia.
Wadeichthys oxyops is an extinct archaeomaenid bony fish from the Koonwarra Lake fauna of Lower Cretaceous Victoria, Australia. If the related genus Koonwarria is regarded as being in a different family, then W. oxyops is the only known Cretaceous-aged archaeomaenid.
Psilichthys is an extinct genus of prehistoric bony fish from the Lower Cretaceous epoch of what is now Victoria, Australia. It has previously been referred to the family Birgeriidae; however it was removed from this family due to differences with Birgeria.
Egertonia is an extinct genus of prehistoric bony fish. The earliest occurrences of the genus in the fossil record are from the Late Cretaceous of Madagascar and India.
Pleuropholis is an extinct genus of prehistoric ray-finned fish.
Peipiaosteus is an extinct genus of prehistoric chondrostean ray-finned fish. Its fossils are found in the Early Cretaceous Jiufotang Formation, Pani Lake, Liaoning Province, China.
Shuleichthys brachypteryx is an extinct species of ray-finned fish which existed in China during the Cretaceous period. Fossils of the fish were found in the Aptian Xiagou Formation of the Changma Basin. It is the only species in the genus Shuleichthys and cannot be placed in any order of the Osteoglossomorpha without making that order paraphyletic.
Ginglymodi is a clade of ray-finned fish containing modern-day gars (Lepisosteidae) and their extinct relatives, including the family Lepidotidae and the orders Semionotiformes and Kyphosichthyiformes, and various other extinct taxa. Ginglymodi is one of the two major subgroups of the infraclass Holostei, the other one being Halecomorphi, which contains the bowfin and its fossil relatives.
