Koonwarria
''Koonwarria manifrons'' is an extinct genus of ray-finned fish that lived in a polar lake in what is now Koonwarra, Victoria, Australia during the Early Cretaceous epoch. Fossils have been retrieved from the Strzelecki Group.Waldman, Michael. Fish from the freshwater Lower Cretaceous of Victoria, Australia: with comments on the palaeo-environment. No. 9. Palaeontological Association, 1971/ref> ''Koonwarria manifrons'' shares many anatomical similarities with the family Archaeomaenidae, and is assumed to be descended from the archaeomaenids, but, is regarded as distinct enough to be placed in its own monotypic family, Koonwarriidae.

Archaeomaenidae
Archaeomaenidae is an extinct family of stem- teleost fish found in freshwater environments of Jurassic New South Wales of Australia, China, and Antarctica, and in Lower Cretaceous New South Wales and Mongolia. Archaeomaenidae was originally erected by the Belgian zoologist George Albert Boulenger for the (then) two species of '' Archaeomaene'' (''A. tenuis'' and ''A. robustus'') of the Talbragar fishbeds, which had originally been assigned to the family Pholidophoridae. It was later expanded to include the other Talbragar fish genera ''Aetheolepis'' and '' Aphnelepis'' as well. In 1941, ''Archaeomaene robustus'' was moved to the new genus ''Madariscus'' by R. T. Wade; however, a 2021 study found that this species most likely represents mature individuals of ''Archaeomaene tenuis'', and is thus a junior synonym of it. Additionally, the archaeomaenid affinities of ''Aetheolepis'' and ''Aphnelepis'' have been questioned, with ''Aetheolepis'' more recently being interpreted as a mem ...

Early Cretaceous
The Early Cretaceous (geochronological name) or the Lower Cretaceous ( chronostratigraphic name), is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from 145 Ma to 100.5 Ma. Geology Proposals for the exact age of the Barremian-Aptian boundary ranged from 126 to 117 Ma until recently (as of 2019), but based on drillholes in Svalbard the defining early Aptian Oceanic Anoxic Event 1a (OAE1a) was carbon isotope dated to 123.1±0.3 Ma, limiting the possible range for the boundary to c. 122–121 Ma. There is a possible link between this anoxic event and a series of Early Cretaceous large igneous provinces (LIP). The Ontong Java- Manihiki- Hikurangi large igneous province, emplaced in the South Pacific at c. 120 Ma, is by far the largest LIP in Earth's history. The Ontong Java Plateau today covers an area of 1,860,000 km2. In the Indian Ocean another LIP began to form at c. 120 Ma, the Kergue ...

Prehistoric Fish Of Australia
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Fish Of Australia
Freshwater fish of Australia are limited to approximately 280 species, even though the Australian continent is larger than the contiguous United States. The small scale of species found in Australian inland waters is in some part due to the dry conditions of the continent. Rainfall is sporadic over much of the continent, and fish cannot live in many of the desert regions of South Australia and Western Australia. Most freshwater species are found in tropical or subtropical regions. A large proportion of freshwater species are endemic to Australia. The family Percicthyidae (temperate perches) and other families suspected in reality to lie within it (e.g. Gadopsidae, Nannopercidae) have risen to prominence in and dominate many of its freshwater systems, in contrast to the Northern Hemisphere where freshwater fish faunas are overwhelmingly dominated by the carp family, Cyprinidae. (No cyprinid species is native to Australia). Due to the illegal introduction of carp (''Cyprinus carpio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna Of Victoria (Australia)
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is ''funga''. Flora, fauna, funga and other forms of life are collectively referred to as ''biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Greek equivalent of fauna. ''Fauna'' is also the word for a book that catalogues the animals in such a manner. The term was first used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Fish Genera
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh ...

Cretaceous Animals Of Australia
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now- extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth by t ...
