Eocypraeidae
Eocypraeidae is a small family of large sea snails, marine gastropod molluscs in the superfamily Cypraeoidea, the cowries and cowry allies. MolluscaBase eds. (2022). MolluscaBase. Eocypraeidae F. A. Schilder, 1924. Accessed through: World Register of Marine Species at: https://www.marinespecies.org/aphia.php?p=taxdetails&id=878564 on 2022-06-19 The family Eocypraeidae consists mainly of fossil species, except for two species: '' Sphaerocypraea incomparabilis'' Briano, 1993 (regarded as valid) and an as yet undescribed species found in the southern Atlantic. In 1963, a fresh shell of what was subsequently named ''Sphaerocypraea incomparabilis'' was dredged up by a Soviet trawler in the Gulf of Aden. There are currently (2009) only six known specimens of this shell in various collections. Taxonomy The taxonomy of Eocypraeidae is not fully understood and has undergone several modifications. 2005 taxonomy According to the taxonomy of Bouchet & Rocroi (2005) this family be ...

Ovulidae
Ovulidae, common names the ovulids, cowry allies or false cowries, is a family of small to large predatory or parasitic sea snails, marine gastropod molluscs in the superfamily Cypraeoidea, the cowries and the cowry allies. MolluscaBase eds. (2020). MolluscaBase. Ovulidae J. Fleming, 1822. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=1747 on 2020-05-25 Distribution The ovulids are a widespread family, occurring mostly in tropical and subtropical waters, with most species in the Indo-West Pacific region. But a few species live in temperate waters. Habitat Ovulids are carnivorous molluscs that feed on polyps and tissues of Anthozoa (as do the genera ''Cyphoma'' and ''Pseudocyphoma''). They live on, and eat, soft corals and sea fans, and they are usually regarded as ectoparasites of these sessile colonial organisms, to which they are anchored by a long and narrow foot. This extreme specialisation in their alimen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cypraeoidea
Cypraeoidea, the cowries and cowry allies, is a superfamily of sea snails, marine gastropods included in the clade Littorinimorpha. This superfamily had been called Cypraeacea and was named by Rafinesque in 1815.MolluscaBase (2018). Cypraeoidea Rafinesque, 1815. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=14774 on 2018-07-18 Shell description This superfamily of sea snails have adult shells which do not look like typical gastropod shells because the spire of the shell is not visible in adults, instead the shells are: often quite rounded in shape, varying from globular to elongate, and with a long, very narrow, aperture which is sometimes toothed. The snails in these families have no operculum. The shells of almost every species in this superfamily are very smooth and shiny, and this is because in the living animal, the shell is nearly always fully covered with the mantle. The largest known fossil cowry was ''G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Extinction
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles-François Fontannes
Charles-François Fontannes, name sometimes given as Francisque Fontannes (1839, Lyon – December 1886) was a French paleontologist and stratigrapher. He was initially a student of commerce, taking business classes in Germany and England. After accompanying Louis Lortet on a scientific excursion to Greece, he took courses in geology at the University of Lyon and became associated with the natural history museum of Lyon. Since 1888 the "Prix Fontannes" is awarded periodically by the Société géologique de France for the best French work in the field of stratigraphy. Published works From 1875 to 1885, in eight installments, he published ''Études stratigraphiques et paléontologiques pour servir à l'histoire de la période tertiaire dans le bassin du Rhône'' ("Stratigraphic and paleontological studies associated with the history of the Tertiary era of the Rhône basin"). Other significant works by Fontannes are: * ''Déscription des ammonites de la zone à Ammonites tenuilob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
