Busycon Contrarium
''Sinistrofulgur contrarium'' is a fossil snail species of the busycon whelks in the family Busyconidae. There has been some confusion about the correct taxonomy of this species, which has been confused with the extant species '' Sinistrofulgur sinistrum'' Hollister, 1958, and ''Sinistrofulgur perversum ''Sinistrofulgur perversum'', the lightning whelk, is an edible species of very large predatory sea snail or whelk, a marine gastropod mollusc in the family Busyconidae, the busycon whelks.

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia. During the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

Snail
A snail is, in loose terms, a shelled gastropod. The name is most often applied to land snails, terrestrial pulmonate gastropod molluscs. However, the common name ''snail'' is also used for most of the members of the molluscan class Gastropoda that have a coiled shell that is large enough for the animal to retract completely into. When the word "snail" is used in this most general sense, it includes not just land snails but also numerous species of sea snails and freshwater snails. Gastropods that naturally lack a shell, or have only an internal shell, are mostly called '' slugs'', and land snails that have only a very small shell (that they cannot retract into) are often called ''semi-slugs''. Snails have considerable human relevance, including as food items, as pests, and as vectors of disease, and their shells are used as decorative objects and are incorporated into jewelry. The snail has also had some cultural significance, tending to be associated with lethargy. The sn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Busycon
''Busycon'' is a genus of very large edible sea snails in the subfamily Busyconinae. These snails are commonly known in the United States as ''whelks'' or ''Busycon whelks''. Less commonly they are loosely, and somewhat misleadingly, called "conchs".Bouchet, P. (2015). Busycon Röding, 1798. In: MolluscaBase (2015). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=160183 on 2015-12-03 ''Busycon'' comes from the Greek ''bousykon'' meaning ''large fig'', from ''bous'' meaning ''cow'' and ''sykon'' meaning ''fig''. Shell description Shells of species in this genus can grow to a length of 40 cm. They all have a long siphonal canal. The shells are generally a solid cream, light grey or tan in color, however the shell of the lightning whelk is marked with brown and white streaks. The shell of individuals can sometimes vary quite widely in coloration and sculpture. Behavior Busycon whelks are scavengers and carnivores, ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Sinistrofulgur Sinistrum
''Sinistrofulgur sinistrum'' is an edible species of large predatory sea snail in the family Busyconidae, the busycon whelks. This species is often confused with ''Sinistrofulgur perversum'', and with ''Busycon contrarium'', which is now considered an exclusively fossil species.J. Wise, M. G. Harasewych, R. T.

Description The size of the shell varies between . This species normally has a sinistral (left-handed) shell, thus the scientific name. (When the shell is held with the spiral end up, the opening is on the left side.) The spire is low and the siphonal canal is long. There is a distinct shoulder where the spire meets the body whorl; knobs of small to moderate size are found at the shoulder. The base color of the shell is variable but is usually pale, and the shell is marked with dark ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sinistrofulgur Perversum
''Sinistrofulgur perversum'', the lightning whelk, is an edible species of very large predatory sea snail or whelk, a marine gastropod mollusc in the family Busyconidae, the busycon whelks. This species has a left-handed or sinistral shell. It eats mostly bivalves. There has been some disagreement about the correct scientific name for this species, which has been confused with ''Sinistrofulgur sinistrum'' Hollister, 1958, and ''Busycon contrarium'' (Conrad, 1840), which is an exclusively fossil species.J.

Gastropods Described In 1840
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.
