	Turonian The Turonian is, in the ICS' geologic timescale, the second age in the Late Cretaceous Epoch, or a stage in the Upper Cretaceous Series. It spans the time between 93.9 ± 0.8 Ma and 89.8 ± 1 Ma (million years ago). The Turonian is preceded by the Cenomanian Stage and underlies the Coniacian Stage. At the beginning of the Turonian an oceanic anoxic event (OAE 2) took place, also referred to as the Cenomanian-Turonian boundary event or the "Bonarelli Event". Stratigraphic definition The Turonian (French: ''Turonien'') was defined by the French paleontologist Alcide d'Orbigny (1802–1857) in 1842. Orbigny named it after the French city of Tours in the region of Touraine (department Indre-et-Loire), which is the original type locality. The base of the Turonian Stage is defined as the place where the ammonite species '' Watinoceras devonense'' first appears in the stratigraphic column. The official reference profile (the GSSP) for the base of the Turonian is located ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Pliosauroid Pliosauroidea is an extinct clade of plesiosaurs, known from the earliest Jurassic to early Late Cretaceous. They are best known for the subclade Thalassophonea, which contained crocodile-like short-necked forms with large heads and massive toothed jaws, commonly known as pliosaurs. More primitive non-thalassophonean pliosauroids resembled pleisiosaurs in possessing relatively long necks and smaller heads. They originally included only members of the family Pliosauridae, of the order Plesiosauria, but several other genera and families are now also included, the number and details of which vary according to the classification used. The distinguishing characteristics are a short neck and an elongated head, with larger hind flippers compared to the fore flippers, the opposite of the plesiosaurs. They were carnivorous and their long and powerful jaws carried many sharp, conical teeth. Pliosaurs range from 4 to 15 metres and more in length. Their prey may have included fish, sharks, ...

	Brimosaurus ''Brimosaurus'' (meaning "strong lizard") is an extinct genus of plesiosaur from the Late Cretaceous of what is now Arkansas. The type species is ''Brimosaurus grandis'', first named by Joseph Leidy in 1854. The name ''Brimosaurus'' is a ''nomen dubium'': the fossils consist of only a few isolated vertebrae, and in 1952 Welles proposed that ''Brimosaurus'' was actually synonymous with ''Cimoliasaurus'' (which itself is based on dubious material).

picture info	Plesiosauroid Plesiosauroidea (; Greek: 'near, close to' and 'lizard') is an extinct clade of carnivorous marine reptiles. They have the snake-like longest neck to body ratio of any reptile. Plesiosauroids are known from the Jurassic and Cretaceous periods. After their discovery, some plesiosauroids were said to have resembled "a snake threaded through the shell of a turtle", although they had no shell. Plesiosauroidea appeared at the Early Jurassic Period (late Sinemurian stage) and thrived until the K-Pg extinction, at the end of the Cretaceous Period. The oldest confirmed plesiosauroid is ''Plesiosaurus'' itself, as all younger taxa were recently found to be pliosauroids. While they were Mesozoic diapsid reptiles that lived at the same time as dinosaurs, they did not belong to the latter. Gastroliths are frequently found associated with plesiosaurs. History of discovery The first complete plesiosauroid skeletons were found in England by Mary Anning, in the early 19th century, an ...

	Albany Museum, South Africa The Albany Museum, South Africa is situated in Grahamstown in South Africa, is affiliated to Rhodes University and dates back to 1855,Chinsamy, Anusuya. (1997). "Albany Museum, Grahamstown, South Africa." ''Encyclopedia of Dinosaurs''. Edited by Phillip J. Currie and Kevin Padian. Academic Press. p. 6. making it the second oldest museum in South Africa. The natural history and geology collections of the '' Eastern Province Literary, Scientific and Medical Society'' were used as its nucleus. The herbarium is staffed by the South African National Biodiversity Institute and has material dating back to 1812, collected by William John Burchell, and a collection of 240 specimens donated by Constance Georgina Adams in 1919, as well as geological material gathered by Andrew Geddes Bain and W. G. Atherstone. It also houses a large collection of invertebrate, vertebrate and tetrapod fossils (some of which are from the world renowned Waterloo Farm lagerstätte), and palaeolithic stone too ...

	1850s In Paleontology Year 185 ( CLXXXV) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Lascivius and Atilius (or, less frequently, year 938 ''Ab urbe condita''). The denomination 185 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
