Mandageria
''Mandageria fairfaxi'' (Pronunciation: Man-daj-ee-ree-a fair-fax-i) is an extinct lobe-finned fish that lived during the Late Devonian period (Frasnian – Famennian). It is related to the much larger ''Hyneria''; although ''Mandageria'' was smaller, it probably hunted in the same way. The generic epithet, ''Mandageria'', refers to the Mandagery Sandstone, outcropping near Canowindra, Australia, where the fossils were found. The specific epithet, ''fairfaxi'', honors the philanthropist James Fairfax. ''M. fairfaxi'' is the state fossil emblem for New South Wales. Description ''Mandageria'' was a large predator about long. It had a long torpedo-shaped body and large tail fins. ''Mandageria'' also had large pectoral fins which could have helped it manoeuvre around submerged logs when preparing to attack its prey. ''Mandageria'' had a functional neck joint, an otherwise uncommon feature among fish - ''Tiktaalik'', '' Tarrasius'', placoderms (esp. Arthrodira) and seahorses A ...

Tristichopterids
Tristichopterids (Tristichopteridae) were a diverse and successful group of tetrapodomorph fishes living throughout the Middle and Late Devonian. They first appeared in the Eifelian stage of the Middle Devonian. Within the group sizes ranged from a few tens of centimeters (''Tristichopterus'') to several meters (''Hyneria'' and ''Eusthenodon''). Some tristichopterids share some of the features of the elpistostegalians, a diverse clade of fishes close to the origin of (and including) tetrapods. This mainly concerns the shape of the skull and a reduction in size of the posterior fins. An old and persistent notion is that ''Eusthenopteron'' was able to crawl onto land using its fins. However, there is no evidence actually supporting this idea.M. Laurin, F. J. Meunier, D. Germain, and M.

Mandagery Sandstone
The Mandagery Sandstone is a Late Devonian geological formation in New South Wales, Australia. It is one of several famed Australian lagerstätten, with thousands of exceptional fish fossils found at a site near the town of Canowindra. A sandstone block containing 114 fish was discovered in 1956 about 10 km west of Canowindra, on the road to Gooloogong. The Canowindra site was rediscovered by paleontologist Alex Ritchie in 1993, and over 3000 fish fossils have been catalogued and stored at the Australian Museum in Sydney and the local Age of Fishes Museum in Canowindra. Antiarch placoderms make up the majority of specimens recovered; '' Bothriolepis'' and '' Remigolepis'' are the most abundant fossils, followed by the arthrodire ''Groenlandaspis''. About 20 sarcopterygian (lobe-finned fish) fossils have also been found, including new taxa such as '' Canowindra,'' '' Mandageria'', ''Cabonnichthys,'' '' Soederberghia'' and ''Gooloogongia.'' Fossils are preserved as natural m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canowindra
Situated on the Belubula River, Canowindra (pronounced ) is a historic township and largest population centre in Cabonne Shire and is located between Orange and Cowra in the central west of New South Wales, Australia. The curving main street, Gaskill Street, is partly an urban conservation area. Toponymy The name of the town is derived from an Aboriginal language (Wiradjuri) word meaning 'a home' or 'camping place'.{{Cite web , url=http://www.anps.org.au/Canowindra.html , title=ANPS - Working on Canowindra , access-date=15 May 2018 , archive-url=https://web.archive.org/web/20180309224619/http://anps.org.au/Canowindra.html , archive-date=9 March 2018 , url-status=dead History Prior to the arrival of Europeans to Australia, the area now known as Canowindra was occupied for tens of thousands of years by a people known as the Wiradjuri.

Tiktaalik
''Tiktaalik'' (; Inuktitut ) is a monospecific genus of extinct sarcopterygian (lobe-finned fish) from the Late Devonian Period, about 375 Mya (million years ago), having many features akin to those of tetrapods (four-legged animals). It may have grown up to in length. Unearthed in Arctic Canada, ''Tiktaalik'' is a non-tetrapod member of Osteichthyes (bony fish), complete with scales and gills – but it has a triangular, flattened head and unusual, cleaver-shaped fins. Its fins have thin ray bones for paddling like most fish, but they also have sturdy interior bones that would have allowed Tiktaalik to prop itself up in shallow water and use its limbs for support as most four-legged animals do. Those fins and other mixed characteristics mark ''Tiktaalik'' as a crucial transition fossil, a link in evolution from swimming fish to four-legged vertebrates. This and similar animals might be the common ancestors of all vertebrate terrestrial fauna: amphibians, reptiles, birds, and m ...

Late Devonian
The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, where rocks from this period were first studied. The first significant adaptive radiation of life on dry land occurred during the Devonian. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants appeared. The arthropod groups of myriapods, arachnids and hexapods also became well-established early in this period, after starting their expansion to land at least from the Ordovician period. Fish reached substantial diversity during this time, leading the Devonian to often be dubbed the Age of Fishes. The placoderms began dominating al ...

Prehistoric Lobe-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] |
Seahorses
A seahorse (also written ''sea-horse'' and ''sea horse'') is any of 46 species of small marine fish in the genus ''Hippocampus''. "Hippocampus" comes from the Ancient Greek (), itself from () meaning "horse" and () meaning "sea monster" or "sea animal". Having a head and neck suggestive of a horse, seahorses also feature segmented bony armour, an upright posture and a curled prehensile tail. Along with the pipefishes and seadragons (''Phycodurus'' and ''Phyllopteryx'') they form the family Syngnathidae. Habitat Seahorses are mainly found in shallow tropical and temperate salt water throughout the world, from about 45°S to 45°N. They live in sheltered areas such as seagrass beds, estuaries, coral reefs, and mangroves. Four species are found in Pacific waters from North America to South America. In the Atlantic, ''Hippocampus erectus'' ranges from Nova Scotia to Uruguay. '' H. zosterae'', known as the dwarf seahorse, is found in the Bahamas. Colonies have been found in Euro ...

Arthrodira
Arthrodira (Greek for "jointed neck") is an order of extinct armored, jawed fishes of the class Placodermi that flourished in the Devonian period before their sudden extinction, surviving for about 50 million years and penetrating most marine ecological niches. Arthrodires were the largest and most diverse of all groups of Placoderms. Description Arthrodire placoderms are notable for the movable joint between armor surrounding their heads and bodies. Like all placoderms, they lacked distinct teeth; instead, they used the sharpened edges of a bony plate on their jawbone as a biting surface. The eye sockets are protected by a bony ring, a feature shared by birds and some ichthyosaurs. Early arthrodires, such as the genus ''Arctolepis'', were well-armoured fishes with flattened bodies. The largest member of this group, ''Dunkleosteus'', was a true superpredator of the latest Devonian period, reaching as much as 6 m in length. In contrast, the long-nosed ''Rolfosteus'' measured just ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Placoderms
Placodermi (from Greek πλάξ 'plate' and δέρμα 'skin', literally 'Plate (animal anatomy), plate-skinned') is a Class (biology), class of armoured prehistoric fish, known from fossils, which lived from the Silurian to the end of the Devonian period. Their head and thorax were covered by articulated armoured plates and the rest of the body was scale (zoology), scaled or naked, depending on the species. Placoderms were among the first jawed fish; their Fish jaw, jaws likely evolved from the first of their gill arches. Placoderms are thought to be paraphyly, paraphyletic, consisting of several distinct Outgroup (cladistics), outgroups or sister taxon, sister taxa to all living jawed vertebrates, which originated among their ranks. In contrast, one 2016 analysis concluded that placodermi are likely monophyletic, though these analyses have been further dismissed with more transitional taxa between placoderms and modern gnathosthomes, solidifying their paraphyletic status.

Government Of New South Wales
The Government of New South Wales, also known as the NSW Government, is the Australian state democratic administrative authority of New South Wales. It is currently held by a coalition of the Liberal Party and the National Party. The Government of New South Wales, a parliamentary constitutional monarchy, was formed in 1856 as prescribed in its Constitution, as amended from time to time. Since the Federation of Australia in 1901, New South Wales has been a state of the Commonwealth of Australia, and the Constitution of Australia regulates its relationship with the Commonwealth. Under the Australian Constitution, New South Wales, as with all states, ceded legislative and judicial supremacy to the Commonwealth, but retained powers in all matters not in conflict with the Commonwealth. Executive and judicial powers New South Wales is governed according to the principles of the Westminster system, a form of parliamentary government based on the model of the United Kingdom.
