Uarbryichthys
''Uarbryichthys'' is a genus of primitive ginglymodian ray-finned fish from fossil beds near the Talbragar River Bed. The various species were lake-dwelling fish that lived during the Upper Jurassic of Australia, and are closely related to the macrosemiids. The living animal would have had a superficial resemblance to a very small porgie, scup, or sea bream, but with a heterocercal Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish.

Jurassic Bony Fish
The Jurassic ( ) is a geologic period and stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and is the only boundary between geological periods to remain formally undefined. By the beginning of the Jurassic, t ...

Prehistoric Ray-finned Fish Genera
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. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heterocercal
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to lur ...

Scup
The scup (''Stenotomus chrysops'') is a fish which occurs primarily in the Atlantic from Massachusetts to South Carolina. Along with many other fish of the family Sparidae, it is also commonly known as porgy. Scup grow as large as 18 in (450 mm) and weigh 3 to 4 lb (2 kg), but they average 0.5–1.0 lb (0.25–0.50 kg). Scup can live up to 20 years; females can begin to reproduce at the age of two. Every year female scups lay approximately 7,000 eggs in sand and weed abundant areas. In the Middle Atlantic Bight, scup spawn along the inner continental shelf. Their larvae end up in inshore waters, along the coast and in estuarine areas. At two to three years of age, they mature. Scup winter along the mid and outer continental shelf. When the temperature warms in the spring, they migrate inshore. They are fished for by both commercial and recreational fishermen. The scup fishery is one of the oldest in the United States, with records dating back to 1800. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porgie
The Sparidae are a family of fish in the order Perciformes, commonly called sea breams and porgies. The sheepshead, scup, and red seabream are species in this family. Most sparids are deep-bodied compressed fish with a small mouth separated by a broad space from the eye, a single dorsal fin with strong spines and soft rays, a short anal fin, long pointed pectoral fins and rather large firmly attached scales. They are found in shallow temperate and tropical waters and are bottom-dwelling carnivores. There are hermaphrodites in the Sparidae. Protogyny and protandry appear sporadically through this lineage of fish. Simultaneous hermaphrodites and bi-directional hermaphrodites do not appear as much since Sparidae are found in shallower waters. Species of fish that express a hermaphroditic condition usually "lack a genetic hardwire", therefore ecological factors play a role in sex determination. Most species possess grinding, molar-like teeth. Eating the head is known to cause hallu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ginglymodi
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. Fossil record The fossil record of ginglymodians goes back at least to the Anisian stage of the Triassic period, over 240 million years ago. '' Eosemionotus'' is one of the earliest ginglymodians. '' Acentrophorus'', another taxon from the Wuchiapingian stage of the late Permian, and '' Paracentrophorus'' from the Early Triassic epoch, could be even earlier members of the group. Ginglymodi was diverse and widespread during the Mesozoic era, but they represent a depauperate lineage today. The group first evolved in marine environments, but several lineages made separate transitions into fre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Talbragar River
Talbragar River, a perennial stream that is part of the Macquarie catchment within the Murray–Darling basin, is located in the Orana district of New South Wales, Australia. The river rises on the western side of the Liverpool Range on south slopes of Great Dividing Range, north of Cassilis and flows generally south west, joined by fifteen tributaries, including the Coolaburragundy River, and reaching its confluence with the Macquarie River near Dubbo; descending over its course. The river flows through the Dunedoo and is noted for its influence on flood, particularly for its capacity for rapid rise and fall, due to the wide catchment, and the effect of its flood water on Dubbo. European history The Talbragar River was first encountered by Europeans in the late 1820s when it was called the Putterbatta River. The first bridge over the Talbragar was built in the 1850s, near Dunedoo, by Thomas New. See also * Rivers of New South Wales * List of rivers of Australia * Talbra ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
