Bolinus Brandaris
''Bolinus brandaris'' (originally called ''Murex brandaris'' by Linnaeus and also Haustellum brandaris), and commonly known as the purple dye murex or the spiny dye-murex, is a species of medium-sized predatory sea snail, an edible marine gastropod mollusk in the family Muricidae, the murex snails or the rock snails. This species is known in the fossil record from the Pliocene (age range: from 3.6 to 2.588 million years ago). Fossil shells of this species have been found in Cyprus, Spain and Italy. It was used by the Phoenicians in ancient times to extract imperial Tyrian purple dye. Distribution and habitat This snail lives in the central and western parts of the Mediterranean Sea and has been found on isolated coral atoll beaches in the Indian Ocean and South China Sea. It was known since ancient times as a source for purple dye and also as a popular food source under various names, among which ''sconciglio'', from which comes the word '' scungilli''. This species lives ...

Pliocene
The Pliocene ( ; also Pleiocene) is the epoch (geology), epoch in the geologic time scale that extends from 5.33 to 2.58See the 2014 version of the ICS geologic time scale
million years ago (Ma). It is the second and most recent epoch of the Neogene Period in the Cenozoic, Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian Stage, which lasted from 2.59 to 1.81 Ma, and is now included in the Pleistocene. As with other older geologic periods, the Stratum, geological strata that define the start and end are well-identified but the exact dates of the start a ...

Tyrian Purple
Tyrian purple ( ''porphúra''; ), also known as royal purple, imperial purple, or imperial dye, is a reddish-purple natural dye. The name Tyrian refers to Tyre, Lebanon, once Phoenicia. It is secreted by several species of predatory sea snails in the family Muricidae, rock snails originally known by the name Murex ('' Bolinus brandaris'', '' Hexaplex trunculus'' and '' Stramonita haemastoma''). In ancient times, extracting this dye involved tens of thousands of snails and substantial labour, and as a result, the dye was highly valued. The coloured compound is 6,6'-dibromoindigo. History Biological pigments were often difficult to acquire, and the details of their production were kept secret by the manufacturers. Tyrian purple is a pigment made from the mucus of several species of murex snail. Production of Tyrian purple for use as a fabric dye began as early as 1200 BC by the Phoenicians, and was continued by the Greeks and Byzantine Empire, Romans until 1453 AD, with ...

Bolinus Brandaris Cagliaritanus
''Bolinus'' is a genus of sea snails, marine gastropod mollusks in the family Muricidae, the murex snails or rock snails. This genus is known in the fossil record from the Miocene to the Pliocene period (age range: from 15.97 to 2.588 million years ago.). Fossil shells within this genus have been found in Cyprus, Austria, Italy and Turkey. Some species of these molluscs were known since ancient times as a source for purple dye and also as a popular food source. Description The adult shells of ''Bolinus'' species can reach a size of about . They are usually pale or golden brown, thick and spiny with a long and straight siphonal canal and a rounded and broad body whorl. They are carnivorous and predatory Distribution Snails within this genus mainly live along the Atlantic coast of Africa and in the Mediterranean Sea. Habitat They inhabit shallow water and prefer gravelled or rocky substrate. Species Species within the genus ''Bolinus'' include: * ''Bolinus brandaris ''Boli ...

ICZN
The International Code of Zoological Nomenclature (ICZN) is a widely accepted convention in zoology that rules the formal scientific naming of organisms treated as animals. It is also informally known as the ICZN Code, for its formal author, the International Commission on Zoological Nomenclature (which shares the acronym "ICZN"). The rules principally regulate: * How names are correctly established in the frame of binominal nomenclature * How to determine whether a given name is available * Which available name must be used in case of name conflicts ( valid name) * How scientific literature must cite names Zoological nomenclature is independent of other systems of nomenclature, for example botanical nomenclature. This implies that animals can have the same generic names as plants (e.g. there is a genus '' Abronia'' in both animals and plants). The rules and recommendations have one fundamental aim: to provide the maximum universality and continuity in the naming of all anima ...

National Gallery Of Art
The National Gallery of Art is an art museum in Washington, D.C., United States, located on the National Mall, between 3rd and 9th Streets, at Constitution Avenue NW. Open to the public and free of charge, the museum was privately established in 1937 for the American people by a joint resolution of the United States Congress. Andrew W. Mellon donated a substantial art collection and funds for construction. The core collection includes major works of art donated by Paul Mellon, Ailsa Mellon Bruce, Lessing J. Rosenwald, Samuel Henry Kress, Samuel Henry Kress#Biography, Rush Harrison Kress, Peter Arrell Browne Widener, Joseph E. Widener, and Chester Dale. The Gallery's collection of paintings, drawings, prints, photographs, sculpture, medals, and decorative arts traces the development of Western art from the Middle Ages to the present, including the only painting by Leonardo da Vinci in the Americas and the largest mobile created by Alexander Calder. The Gallery's campus includes the ...

Martin Lister
Martin Lister (12 April 1639 – 2 February 1712) was an English natural history, naturalist and physician. His daughters Anne Lister (illustrator), Anne and Susanna Lister, Susanna were two of his illustrators and engravers. J. D. Woodley, 'Lister , Susanna (bap. 1670, d. 1738)', Oxford Dictionary of National Biography, Oxford University Press, 2004; online edn, Jan 200accessed 10 April 2017/ref> Life Lister was born at Radclive, Radcliffe, near Buckingham, the son of Martin Lister (MP), Sir Martin Lister MP for Brackley in the Long Parliament and his wife Susanna Temple, a daughter of Alexander Temple, Sir Alexander Temple. Lister was connected to a number of well known individuals. He was the nephew of both James Temple, the regicide and also of Matthew Lister (died 1657), Matthew Lister, physician to Anne of Denmark, Anne, queen of James I of England, James I, and to Charles I of England, Charles I. He was also the uncle of Sarah Churchill, Duchess of Marlborough who corre ...

Spire (mollusc)
A spire is a part of the coiled shell of molluscs. The spire consists of all of the whorls except for the body whorl. Each spire whorl represents a rotation of 360°. A spire is part of the shell of a snail, a gastropod mollusc, a gastropod shell, and also the whorls of the shell in ammonites, which are fossil shelled cephalopods. In textbook illustrations of gastropod shells, the tradition (with a few exceptions) is to show most shells with the spire uppermost on the page. The spire, when it is not damaged or eroded, includes the protoconch (also called the nuclear whorls or the larval shell), and most of the subsequent teleoconch whorls (also called the postnuclear whorls), which gradually increase in area as they are formed. Thus the spire in most gastropods is pointed, the tip being known as the " apex". The word "spire" is used, in an analogy to a church spire or rock spire, a high, thin, pinnacle. The "spire angle" is the angle, as seen from the apex, at which a s ...

Whorl (mollusc)
A whorl is a single, complete 360° revolution or turn in the spiral or whorled growth of a mollusc shell. A spiral configuration of the shell is found in numerous gastropods, but it is also found in shelled cephalopods including ''Nautilus'', ''Spirula'' and the large extinct subclass of cephalopods known as the ammonites. A spiral shell can be visualized as consisting of a long Cone (geometry), conical tube, the growth of which is coiled into an overall Helix, helical or planispiral shape, for reasons of both strength and compactness. The number of whorls which exist in an adult shell of a particular species depends on mathematical factors in the geometric growth, as described in D'Arcy Wentworth Thompson's classic 1917 book ''On Growth and Form'', and by David Raup. The main factor is how rapidly the conical tube expands (or flares-out) over time. When the rate of expansion is low, such that each subsequent whorl is not that much wider than the previous one, then the adult s ...

Siphon (mollusc)
A siphon is an anatomical structure which is part of the body of aquatic molluscs in three Class (biology), classes: Gastropoda, Bivalvia and Cephalopoda (members of these classes include saltwater and freshwater snails, clams, octopus, squid and relatives). Siphons in molluscs are tube-like structures in which water (or, more rarely, air) flows. The water flow is used for one or more purposes such as animal locomotion, locomotion, feeding, respiration (physiology), respiration, and reproduction. The siphon is part of the mantle (mollusc), mantle of the mollusc, and the water flow is directed to (or from) the Mantle (mollusc)#The mantle cavity, mantle cavity. A single siphon occurs in some gastropods. In those bivalves which have siphons, the siphons are paired. In cephalopods, there is a single siphon or funnel which is known as a hyponome. In gastropods In some (but not all) sea snails, Marine (ocean), marine gastropod molluscs, the animal has an anterior extension of the man ...
