Gogo Formation
The Gogo Formation in the Kimberley region of Western Australia is a Lagerstätte that exhibits exceptional preservation of a Devonian reef community. The formation is named after Gogo Station, a cattle station where outcrops appear and fossils are often collected from, as is nearby Fossil Downs Station. History The reef, which now stands up abruptly in the western Australian desert (as the Windjana Limestone), was first identified in 1940 by paleontologist Curt Teichert, who discovered the first fossil fish from the region. Sedimentology Unweathered sections of the Gogo Formation are made of siltstone, shale and calcarenite with numerous limestone concretions. These concretions are resistant to weathering, producing extensive nodule fields on the ground in areas where the surrounding rock has eroded away. The Gogo sediments represent deep, hypoxic seafloor deposits in the vicinity of a large tropical reef composed primarily of algae and stromatoporoids during the Fras ...

Argoubia
''Argoubia'' is an extinct genus of devil ray from the Paleogene period. It is named for the town of El Argoub, Morocco. The type species, ''A. barbei'', is from the Priabonian-aged Samlat formation of Morocco. The specific epithet honors Mr. Gérard Barb who helped collect the first specimens of this species. ''A. arnoldmülleri'' is a second species from the middle Oligocene Böhlen Formation of the Zwenkau lignite mines of Germany. It is named for Dr. Arnold Müller, curator A curator (from la, cura, meaning "to take care") is a manager or overseer.

Sclerorhynchidae
Ganopristidae is an extinct family of cartilaginous fish from the Cretaceous belonging to the suborder Sclerorhynchoidei. While the name Sclerorhynchidae is often used for this family, it is a junior synonym of Ganopristidae. This family contains the genera '' Libanopristis'', ''Micropristis'', and ''Sclerorhynchus ''Sclerorhynchus'' (from el, σκληρός , 'hard' and el, ῥύγχος 'snout') is an extinct genus of ganopristid sclerorhynchoid that lived during the Late Cretaceous.

Agaleorhynchus
''Agaleorhynchus'' is an extinct genus of Sclerorhynchidae from the Cretaceous period. It is named after Professor Andy Gale, in recognition of his work on Cretaceous chalk stratigraphy. It is known from a single species, ''A. britannicus'', which is currently restricted to the middle Santonian to early Campanian of southern England England is a country that is part of the United Kingdom.

Abdounia Vassilyevae
''Abdounia'' is an extinct genus of requiem shark which lived during the Paleogene period. It is mainly known from isolated teeth. It is one of the earliest requiem sharks, and attained widespread success in North America, Europe, and Africa. Locations They are known from the paleogene of Morocco, France, Belgium, Russia, North Carolina, Georgia, Alabama, and Virginia. In the lower Nanjemoy Formation of Virginia, they are the most common fossil shark tooth. By the end of the Oligocene Epoch the genus is severely reduced, probably due to competition with other Carcharhiniformes like Carcharhinus. Species The following are species currently attributed to this genus. Note this may be an under-representation of actual diversity, as living relatives have extremely similar teeth across species. *'' Abdounia africana'' (Danian-Thanetian) *'' Abdounia beaugei'' (Paleocene-Eocene ) *'' Abdounia enniskelleni'' (Eocene) *'' Abdounia furimskyi'' (upper Eocene-Rupelian ) *'' Abdounia lapierre ...

Requiem Shark
Requiem sharks are sharks of the family Carcharhinidae in the order Carcharhiniformes. They are migratory, live-bearing sharks of warm seas (sometimes of brackish or fresh water) and include such species as the tiger shark, bull shark, lemon shark, spinner shark, blacknose shark, blacktip shark, grey reef shark, blacktip reef shark, silky shark, dusky shark, blue shark, copper shark, oceanic whitetip shark, and whitetip reef shark. Family members have the usual carcharhiniform characteristics. Their eyes are round, and one or two gill slits fall over the pectoral fin base. Most species are viviparous, the young being born fully developed. They vary widely in size, from as small as adult length in the Australian sharpnose shark, up to adult length in the tiger shark.Compagno, L.J.VFamily Carcharhinidae - Requiem sharksin Froese, R. and D.

Ischnacanthiformes
Ischanacanthiformes is a prehistoric order of Acanthodii or spiny sharks found in Canada, Ukraine and United Kingdom. Members of this order were nektonic carnivores, eating animals that swim rather than plankton. They had slender builds, light armor, deeply inserted spines, shark-like teeth, and two dorsal fin A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Many species of animals possessing dorsal fins are not particularly closely related to each other, though through c ...s. Some species were around 2 meters (6.56 feet) long.
