Φόσα: Διαφορά μεταξύ των αναθεωρήσεων

The Fossa was formally described in 1833 by [[Edward Turner Bennett]]. The [[name of a biological genus|genus name]] ''Cryptoprocta'' refers to how the animal's [[anus]] is hidden by its anal pouch (''crypto-'' is Greek for "hidden", and ''procta'' is Greek for "anus").{{r|1986Köhncke}} The [[species name]] ''ferox'' is Latin for "fierce" or "wild."{{r|1960Borror}} Its [[common name]] is [[Malagasy language|Malagasy]] and can be spelled ''fossa'' or ''fosa''.{{r|1986Köhncke}} The common name is the same as the generic name of the [[Malagasy Civet]] (''Fossa fossana''), but they are different species. Because of shared physical traits with [[civet]]s, [[mongoose]]s, and cats ([[Felidae]]), its [[biological classification|classification]] has been controversial. Bennett originally placed the Fossa as a type of [[civet]] in the family [[Viverridae]], a classification that long remained popular among taxonomists. Its compact [[braincase]], large [[Orbit (anatomy)|eye sockets]], retractable claws, and specialized carnivorous [[dentition]] have also led some taxonomists to associate it with the felids.{{r|2003NatHist-13b}} In 1939, [[William King Gregory]] and Milo Hellman placed the Fossa in its own subfamily within Felidae, the Cryptoproctinae. [[George Gaylord Simpson]] placed it back in Viverridae in 1945, still within its own subfamily, yet admitted it had many cat-like characteristics.{{r|1986Köhncke|2003NatHist-13a}}

In 1993, Géraldine Veron and François Catzeflis published a [[DNA hybridization]] study suggesting that the Fossa was more closely related to mongooses (family Herpestidae) than to cats or civets.{{r|2003NatHist-13b|2003NatHist-13a}} However, in 1995, Veron's [[morphology (biology)|morphological]] study once again grouped it with Felidae.{{r|2003NatHist-13a}} In 2003, [[molecular phylogenetics|molecular phylogenetic]] studies using [[Nuclear DNA|nuclear]] and [[Mitochondrial DNA|mitochondrial genes]] by [[Anne Yoder]] and colleagues showed that all native Malagasy carnivorans share a common ancestry that excludes other carnivores (meaning they form a [[Cladistics|clade]], making them [[Monophyly|monophyletic]]) and are most closely related to Asian and African Herpestidae.{{r|2003Yoder|2004Veron|2007Barycka}} To reflect these relationships, all Malagasy carnivorans are now placed in a single family, [[Eupleridae]].{{r|MSW3}} Within Eupleridae, the Fossa is placed in the subfamily [[Euplerinae]] with the [[Falanouc]] (''Eupleres goudoti'') and [[Malagasy Civet]] (''Fossa fossana''), but its exact relationships are poorly resolved.{{r|MSW3|2003Yoder|2007Barycka}}
