Kollikodon is an extinct species of mammal, considered to be an early monotreme. It is known only from an opalised dentary fragment, with one premolar and two molars in situ, as well as a referred maxillary fragment containing the last premolar and all four molars. The fossils were found in the Griman Creek Formation at Lightning Ridge, New South Wales, Australia. Kollikodon lived in the Late Cretaceous period, during the Cenomanian age. Several other monotremes are known from the Griman Creek Formation, including Dharragarra, Opalios, Parvopalus, Steropodon, and Stirtodon.
Steropodon is a genus of prehistoric platypus-like monotreme, or egg-laying mammal. It contains a single species, Steropodon galmani, that lived about 100.2–96.6 million years ago during the Cretaceous period, from early to middle Cenomanian. It is one of the oldest monotremes discovered, and is one of the oldest Australian mammal discoveries. Several other monotremes are known from the Griman Creek Formation, including Dharragarra, Kollikodon, Opalios, Parvopalus, and Stirtodon.
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.
Anaspidesidae is a family of freshwater crustacean that is endemic to Tasmania, Australia. The family contains 3 living genera. This group of crustaceans are considered living fossils. They are commonly and collectively known as the Tasmanian anaspid crustaceans.
Anaspides is a genus of freshwater crustaceans in the family Anaspidesidae. The genus was first described in 1894 by George Malcolm Thomson. The genus was originally placed in the family, Anaspididae by Thomson, but this genus name was preoccupied by the insect genus, Anaspis Geoffroy, 1762, and therefore, in 2017, the family was renamed Anaspidesidae by Shane Ahyong and Miguel A. Alonso-Zarazaga.
Cooyoo is an extinct genus of ichthyodectid ray-finned fish known from the Lower Cretaceous. It contains a single species, C. australis, known from the Albian-aged Toolebuc and Allaru Formations of Queensland, Australia. C. australis was originally named by Arthur Smith Woodward as a species of Portheus in 1894, which was later amended to Xiphactinus.
Cavenderichthys is an extinct genus of prehistoric freshwater ray-finned fish from the Late Jurassic. It contains a single species, C. talbragarensis from the Talbragar Fish beds of New South Wales, Australia.
Koonwarra is a town in the South Gippsland region of Victoria, Australia. At the 2016 census, Koonwarra had a population of 404. The town straddles the South Gippsland Highway. Located around 128 km southeast of Melbourne, the town was served by rail from the 1890s until 1991 with the closing of the rail line to Barry Beach.
The Talbragar fossil site is a paleontological site of Late Jurassic (Tithonian) age in the central west of New South Wales, Australia. It lies about 30 kilometres (19 mi) north-east of the town of Gulgong, and 300 kilometres (190 mi) north-west of Sydney. The site has been known for over a century during which it has been extensively excavated to the point of near exhaustion. It is now registered as a Crown Land Reserve for the preservation of fossils; access is by permit, and the collection of rocks and fossil specimens is prohibited. The 4-hectare (9.9-acre) reserve is listed on the Register of the National Estate.
Kryoryctes is a genus of prehistoric monotreme mammal from the Early Cretaceous (Albian) Eumeralla Formation of Victoria, Australia from the Otway Group of Dinosaur Cove. It is known only from a partial right humerus, estimated at 106 million years old, and contains one species, Kryoryctes cadburyi. The holotype, NMV P208094, was described in 2005 and is currently housed in the Museums Victoria Palaeontological Collection.
The Tupuangi Formation is a geological formation in New Zealand, only exposed on Pitt Island in the Chatham Islands. It is the oldest exposed sedimentary unit within the archipelago. It was deposited in terrestrial deltaic to paralic conditions during the Cenomanian to Turonian ages of the Late Cretaceous. During this time period the Chatham Islands were attached to Antarctica within the Antarctic Circle, at approximately 70° to 80° south.
Eodermaptera is an extinct suborder of earwigs known from the Middle Jurassic to Mid Cretaceous. Defining characteristics include "tarsi three-segmented, tegmina retain venation, 8th and 9th abdominal tergite in females are narrowed, but separate from 10th tergite and not covered by 7th tergite and exposed ovipositor" They are considered to be more closely related to Neodermaptera than the more basal Archidermaptera.
Zhangsolvidae is an extinct family of brachyceran flies known from the Cretaceous period. Members of the family possess a long proboscis, varying in length between 1.3 and 7 mm depending on the species, and were probably nectarivores. A specimen has been found with preserved Bennettitales pollen, suggesting that they acted as pollinators for extinct gymnosperms. They are considered to be members of the Stratiomyomorpha.
Tarwinia is an extinct genus of stem-group flea known from a single species, T. australis, from the Early Cretaceous (Aptian) Koonwarra Fossil Bed of Victoria, Australia, it is the only member of the family Tarwiniidae, and the only stem-group flea known from the Southern Hemisphere.
Coccolepididae is an extinct family of ray-finned fish, known from the Early Jurassic to Early Cretaceous, most of which were originally referred to the type genus Coccolepis. They had a widespread distribution, being found in North and South America, Australia, Asia and Europe. They are mostly known from freshwater environments, though several species have been found in marine environments. They are morphologically conservative, and have poorly ossified endo and exoskeletons, which usually results in poor preservation. This makes it difficult to distinguish species. They are generally small fish, with the largest known specimens reaching a length of 210 mm. Historically, they have been classified as members of “Palaeonisciformes”, a paraphyletic grouping of non-neopterygian fish, due to their plesiomorphic conservative morphology closely resembling those of many other groups of primitive fish. Some recent authors have suggested that they may belong to the order Chondrostei as relatives of the Acipenseriformes.
Oestokerkus is an extinct genus of Cambrian megacheiran arthropod known from the Emu Bay Shale of Kangaroo Island, Australia. It belongs to the family Leanchoiliidae. It had a large head shield that was more than a third of the trunk's length, as well as a large pair of eyes. The great appendages have long flagellae projecting from them. The head shield probably had two pairs of cephalic appendages. The trunk has 11 segments. The exopods of the biramous limbs are fringed with long setae. The body ended with a telson, which was probably dorsally flattened.
Anaspides jarmani is a species of freshwater crustacean in the family Anaspidesidae, and was first described in 2015 by Shane Ahyong
Anaspides swaini is a species of freshwater crustacean in the family Anaspidesidae, and was first described in 2015 by Shane Ahyong
Anaspides driesseni is a species of freshwater crustacean in the family Anaspidesidae, and was first described in 2023 by Christoph Höpel, Stefan Richter & Shane Ahyong. In 2016 Ahyong discussed three morphologically different forms of A. swaini occurring in three different drainage systems.
Sundrius is an extinct genus of probable monotreme mammal from the Late Cretaceous (Albian) Eumeralla Formation of Australia. The genus contains a single species, S. ziegleri, known from a broken molar.
