Colus
''Colus'' (lat. ''colus'', distaff) is a genus of sea snails, marine gastropod mollusks in the family Colidae, the true whelks and the like. Evolution ''Colus'' is related to the New Zealand genus ''Austrofusus''. Taxonomy The name ''Colus'' is not available from Humphrey, 1797 (published in a work placed on the Official Index). Most recent authors use the name ''Colus'' for the genus instead of ''Sipho'' . Iredale (1919b) mentioned: "This name cannot be defended by anyone" and was rejected by the ICZN (Op. 21). Also ''Tritonofusus'' cannot be used because of the rules of priority. Species Species within the genus ''Colus'' include: * '' Colus aurariae'' Fraussen, Rosado, Afonso & Monteiro, 2009 * '' Colus azygosorius'' Tiba, 1980 * '' Colus barbarinus'' Dall, 1919 * '' Colus bukini'' Kantor, 1984 * '' Colus gracilis'' (da Costa, 1778) * '' Colus griseus'' (Dall, 1889) * '' Colus halimeris'' (Dall, 1919) * '' Colus holboelli'' ( Møller, 1842) * '' Colus islandicus'' ( ...

Buccinidae
The Buccinidae are a very large and diverse taxonomic family of large sea snails, often known as whelks or true whelks.Bouchet, P.; Gofas, S. (2010). Buccinidae. In: Bouchet, P.; Gofas, S.; Rosenberg, G. (2010) World Marine Mollusca database. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=149 on 2010-12-30 The family includes more than 1500 species. Taxonomy The family Busyconidae was for a time treated as a subfamily of Buccinidae called Busyconinae. Genera ''Antillophos'', ''Engoniophos'', ''Phos'', ''Nassaria'', '' Tomlinia'', '' Anentome'' and '' ''Clea'''' were treated within family Buccinidae, but they were moved to Nassariidae in 2016. Habitat The true whelks occur worldwide in all seas from tropical oceans to the cold seas of the Arctic Ocean and the Southern Ocean. They are found from the intertidal to the bathypelagic zones. Most prefer a solid bottom, but some inhabit sandy substrates. Description ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleocene
The Paleocene, ( ) or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by Chicxulub impact, an asteroid impact and possibly volcanism, marked the beginning of the Paleocene and killed off 75% of living species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification.

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] |
