Crassostrea is a genus of true oysters containing some of the most important oysters used for food.
Ostrea is a genus of edible oysters, marine bivalve mollusks in the family Ostreidae, the oysters.
The southern mud oyster, Australian flat oyster, native flat oyster, native mud oyster, or angasi oyster, is endemic to southern Australia, ranging from Western Australia to southeast New South Wales and around Tasmania. Ostrea angasi superficially resembles Ostrea edulis and both species may be referred to with the name "flat oyster". However, the two species do not occur naturally in the same geographic distribution.
Ostrea edulis, commonly known as the European flat oyster, is a species of oyster native to Europe. In Great Britain and Ireland, regional names include Colchester native oyster, mud oyster, or edible oyster. In France, Ostrea edulis are known as huîtres plates except for those that come from the Belon River estuary in Brittany, France, which are known as Belons.
The Aquia Formation is a geologic sandstone formation that extends from the upper Chesapeake Bay to the James River near Hopewell, Virginia. It consists of clayey, silty, very shelly, glauconitic sand. Fossil records indicate that this stratigraphic unit was created during the Paleocene.
Ostrea lurida, common name the Olympia oyster, after Olympia, Washington in the Puget Sound area, is a species of small, edible oyster, a marine bivalve mollusk in the family Ostreidae. This species occurs on the northern Pacific coast of North America. Over the years the role of this edible species of oyster has been partly displaced by the cultivation of non-native edible oyster species.
The dredge oyster, Bluff oyster or Chilean oyster, is also known in Chile as ostra verde, is a species of flat oyster. It is a marine bivalve mollusc of the family Ostreidae.
The Cornbrash Formation is a Middle Jurassic geological formation in England. It ranges in age from Bathonian to Callovian, the uppermost part of the Middle Jurassic. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus. The name Cornbrash is an old English agricultural name applied in Wiltshire to a variety of loose rubble or brash which, in that part of the country, forms a good soil for growing corn. The name was adopted by William Smith for a thin band of shelly limestone which, in the south of England, breaks up in the manner indicated. Although only a thin group of rocks, it is remarkably persistent; it may be traced from Weymouth to the Yorkshire coast, but in north Lincolnshire it is very thin, and probably dies out in the neighborhood of the Humber. It appears again, however, as a thin bed in Gristhorpe Bay, Cayton Bay, Wheatcroft, Newton Dale and Langdale. In the inland exposures in Yorkshire it is difficult to follow on account of its thinness, and the fact that it passes up into dark shales in many places the so-called clays of the Cornbrash, with Avicula echinata. The Cornbrash is of little value for building or road-making, although it is used locally; in the south of England it is not oolitic, but in Yorkshire it is a rubbly, marly, frequently ironshot oolitic limestone. In Bedfordshire it has been termed the Bedford limestone.
The Yorktown Formation is a mapped bedrock unit in the Coastal Plain of Maryland, Virginia, North Carolina and South Carolina. It is overconsolidated and highly fossiliferous.
Stereum ostrea, also called false turkey-tail and golden curtain crust, is a basidiomycete fungus in the genus Stereum. It is a plant pathogen and a wood decay fungus. The name ostrea, from the word 'oyster', describes its shape. With concentric circles of many colors, it highly resembles Trametes versicolor, turkey-tail, and is thus called the 'false turkey-tail'. The stemless fruiting body is shell-like and grows 1–7 cm (0.39–2.76 in) high. It is tough and inedible. It grows on tree bark. This fungus is native to the island of Java, Indonesia and has been misapplied to the North American Stereum species Stereum fasciatum, Stereum lobatum, and Stereum subtomentosum.
Ostrea permollis, the sponge oyster, is a species of bivalve mollusc in the family Ostreidae. It can be found along the Atlantic Coast of North America, ranging from North Carolina to the West Indies.
The Apón Formation is a geological formation in northwestern Venezuela and northern Colombia, whose thick-bedded limestone interbedded with subordinate amounts of dark gray calcareous shale and sandy shale strata date back to the Early Cretaceous. Pterosaur remains of Ornithocheiridae indet. are among the fossils that have been recovered from the formation.
Paleontology in South Carolina refers to paleontological research occurring within or conducted by people from the U.S. state of South Carolina. Evidence suggests that at least part of South Carolina was covered by a warm, shallow sea and inhabited by trilobites during the Cambrian period. Other than this, little is known about the earliest prehistory of South Carolina because the Ordovician, Silurian, Devonian, Carboniferous, Permian, Triassic, and Jurassic, are missing from the state's local rock record. The earliest fossils of South Carolina date back to the Cretaceous, when the state was partially covered by seawater. Contemporary fossils include marine invertebrates and the remains of dinosaur carcasses that washed out to sea. On land, a wide variety of trees grew. Sea levels rose and fell throughout the ensuing Cenozoic era. Local marine life included invertebrates, fish, sharks, whales. The first scientifically accurate identification of vertebrate fossils in North America occurred in South Carolina. In 1725, African slaves digging in a swamp uncovered mammoth teeth, which they recognized as originating from an elephant-like animal.
Ostrea equestris, commonly known as the crested oyster or horse oyster, is a species of bivalve mollusc in the family Ostreidae. It can be found along the Atlantic coast of North and South America, ranging from Virginia to Patagonia.
The Hiló Formation is a geological formation of the Altiplano Cundiboyacense, Eastern Ranges of the Colombian Andes. The predominantly shale formation dates to the Middle Cretaceous period; Late Albian to Early Cenomanian epochs and has a measured thickness at its type section of 470 metres (1,540 ft). The fossiliferous formation has provided a great abundance of ammonites and other marine species.
The Roca Formation is a Cretaceous to Paleogene lithostratigraphic unit, located in the Neuquén Basin. It crops out in the Argentinian provinces of Río Negro, Neuquén, La Pampa, and Mendoza. Its deposition is diachronous, beginning during the Maastrichtian in the north of its distribution, and later moving to the south, where its strata reached the Late Danian. It lies transitionally above the Jagüel Formation, and the top of the formation is marked by a regional unconformity due to an Eocene and Oligocene orogenic pulse. These two units belong to the Malargüe Group. The marine sediments of the Jagüel and Roca Formations were deposited during a transgression from the Atlantic Ocean, beginning in the Maastrichtian and ending in the Danian.
Azabbaremys is an extinct genus of bothremydid pleurodiran turtle that was discovered in the Teberemt Formation of Mali. It was described in 2001, based on a skull that had been recovered in an expedition in 1981. The genus consists solely of the type species Azabbaremys moragjonesi. The genus name is derived from Azabbar, a monster in Tamasheq folk stories. The species is named for Morag Jones, a research student who participated in the discovery of the specimen and died in the expedition. Azabbaremys is most closely related to another Paleocene side-necked turtle, Acleistochelys.
