Sinistrofulgur 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'' (Linnaeus, 1758)J.

Miocene
The Miocene ( ) is the first epoch (geology), 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 followed the Oligocene and preceded 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 distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and Ape, hominoids into Eurasia. During the late Miocene, the conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from 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 () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold Glacial period, glacial periods and warmer Interglacial, int ...

Snail
A snail is a shelled gastropod. The name is most often applied to land snails, terrestrial molluscs, 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 gastropod shell, 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 Snails as food, as food items, as pests, and as vectors of disease, and their shells are used as decorative objects and are incorporated into jewellery. The snail has also had some cultural significance, tending t ... [...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. The shell is pyriform. The body whorl is large, nodulous or spinose. The spire is very short. The aperture is large and subtriangular. The siphonal canal is open, elongated, entire at the fore part. The inner lip is concave, with a single fold anteriorly. The outer lip is internally striated.

Family (biology)
Family (, : ) 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". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Sinistrofulgur Sinistrum
''Sinistrofulgur sinistrum'' is an edible species of large predatory sea snail in the family Busyconidae, the busycon whelks. Taxonomy ''Sinistrofulgur sinistrum'' was named by S. C. Hollister in 1958, originally as ''Busycon (Sinistrofulgur) sinistrum''. It had previously been included in the species ''Busycon contrarium'', now known as ''Sinistrofulgur contrarium'', but ''S. contrarium'' is now considered an exclusively fossil species. A study by Wise and colleagues in 2004 found that the level of genetic divergence between lightning whelk populations in different regions were low enough to be considered a single species with three subspecies, ''Busycon perversum perversum'', ''B. perversum sinistrum'', and ''B. perversum laeostomum''. In contrast, in 2015 Petuch recognized four distinct species, including ''Sinistrofulgur sinistrum'', distinguishing them by their range and shell morphology. As of 2024, ''Sinistrofulgur sinistrum'' is listed as an accepted species on MolluscaBase. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sinistrofulgur Perversum
''Sinistrofulgur perversum'', the lightning whelk, is a 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.

Sanibel Island
Sanibel is an island and city in Lee County, Florida, United States. The population was 6,382 at the 2020 census, down from 6,469 at the 2010 census. It is part of the Cape Coral-Fort Myers, Florida Metropolitan Statistical Area. The island, also known as Sanibel Island, constitutes the entire city. It is a barrier island—a collection of sand on the leeward side of the more solid coral-rock of Pine Island. Most of the city proper is at the island's eastern end. After the Sanibel causeway was built to replace the ferry in 1963, the city was incorporated in 1974, and the residents asserted control over development by establishing the Sanibel Comprehensive Land Use Plan, helping maintain a balance between development and preservation of the island's ecology. In September 2022, the causeway was heavily damaged by Hurricane Ian. Due to easy causeway access, Sanibel is a popular tourist destination known for its shell beaches and wildlife refuges. More than half the island is mad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sinistrofulgur
''Sinistrofulgur'' is a genus of large sea snails with left-handed shell-coiling, marine gastropod mollusks in the subfamily In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end botanical subfamily names with "-oideae", and zo ... Busyconinae. Taxonomy The taxonomy of sinistral busyconids has been subject to several disputes, including at what rank to recognize them as distinct from their sister taxon, '' Busycon carica'', and how many species are represented. Sinistral busyconids were historically included in the genus ''Busycon''. In 1958, Hollister proposed the subgenus ''Sinistrofulgur'' for the group. Petuch elevated ''Sinistrofulgur'' to genus rank in 1994, although some other authors have continued including these snails in the genus ''Busycon''.
