Prehistoric mustelids

Chamitataxus is a prehistoric badger genus. Chamitataxus avitus is the only known species of the genus. Chamitataxus lived during the Late Miocene, around 6 million years ago in what is now North America. Out of the three taxidiine badger genera to have existed on the continent, Chamitataxus is the most primitive. Very few taxideine badger remains have been uncovered to date, with only prehistoric Taxidea and Pliotaxidea specimens being discovered prior to the Chamitataxus holotype being found.

Ekorus ekakeran is a large, extinct mustelid mammal. Fossils, including largely complete skeletons, are known from the late Miocene of Kenya.

Enhydriodon is an extinct genus of otters known from Africa and South Asia that lived from the late Miocene to the early Pleistocene. It contains nine confirmed species, two debated species, and at least a few other undescribed species from Africa. The genus name means "otter tooth" in Ancient Greek and is a reference to its dentition rather than to the Enhydra genus, which includes the modern sea otter and its two prehistoric relatives. Enhydriodon belongs to the tribe Enhydriodontini (which also contains Sivaonyx and Vishnuonyx) in the otter subfamily Lutrinae.

Megalictis (meaning "great weasel") is an extinct genus of large predatory mustelids that existed in North America during the "cat gap" from the Late Arikareean (Ar4) in the Miocene epoch. It is thought to have resembled a huge, jaguar-sized ferret, weighing up to .

Cyrnaonyx is an extinct genus of Lutrinae, otters from the Pleistocene. It was originally described by Helbing based on materials from France and he also attributed material from Corsica to it. The latter appeared to belong to another species and genus, Algarolutra majori. The only species of Cyrnaonyx is C. antiqua. It is known from the Pleistocene (Holsteinian to Eemian/Weichselian) of Europe: France, Germany, Netherlands, Southern England and probably Italy.

Oligobuninae is an extinct subfamily of the family Mustelidae known from Miocene deposits in North America.

Megalenhydris barbaricina is an extinct species of giant otter from the Late Pleistocene of Sardinia. It is known from a single partial skeleton, discovered in the Grotta di Ispinigoli near Dorgali, and was described in 1987. It was larger than any living otter, exceeding the size of South American giant otters (Pteronura), which can reach two meters in length. The species is one of four extinct otter species from Sardinia and Corsica. The others are Algarolutra majori, Lutra castiglionis and Sardolutra ichnusae. It is suggested to have ultimately originated from the much smaller European main

Plesictis is an extinct prehistoric genus of mustelid (originally described as a procyonid) endemic to Europe during the Oligocene and Miocene 33.9—20.0 Ma existing for approximately .

Sardolutra ichnusae is an extinct species of otter from the Late Pleistocene of Sardinia. It was originally described as Nesolutra ichnusae. It was a rather small species of otter, probably living in the sea. Among its characteristics is a relatively very large baculum, larger than in any living otter. The species probably evolved from a species of Lutra, maybe L. castiglionis.

Algarolutra is an extinct endemic genus of otter from the Pleistocene of Corsica and Sardinia. The single species A. majori was originally attributed to the genus Cyrnaonyx and its type species C. antiqua, which was based on fossils from Corsica and also from mainland France. From mainland Europe, only lower dentition was known, whereas from Corsica and Sardinia only upper dentition was known. When a Cyrnaonyx antiqua fossil with both upper and lower dentition was found in England, it became clear that the species majori was too different to keep even in the same genus and the genus Algarolutr

thumb|Plesiogulo marshalli Plesiogulo is a genus of prehistoric carnivore that lived from the Miocene to the Pliocene of Africa, Eurasia, and North America. An ancestral relationship to the wolverine (Gulo gulo) was once suggested, but it is no longer considered likely. However, some authorities still consider it a member of the Guloninae.

Zodiolestes is a genus of mustelids, now extinct, which existed during the Miocene period.

Siamogale is an extinct genus of giant otter from the Late Miocene to Early Pliocene of eastern Asia. Three species are currently known, S. thailandica and S. bounosa from Thailand and S. melilutra from China.

Eomellivora is an extinct genus of prehistoric mustelids, closely related to the honey badger, known from Eurasia and North America, and tentatively Africa. It was one of the biggest mustelids ever known, bigger and more hypercarnivorous than the modern wolverine. Using equations by Legendre (1986) for calculating body mass for mammals through linear dimensions of the first lower molar, Eomellivora averaged roughly 50 kg (based on measurements reported in Valenciano et al., 2015).

Satherium is an extinct genus of otters that lived in North America during the Pliocene and Pleistocene. Two species are known, Satherium piscinarium and Satherium ingens.

species of carnivore (fossil)

Pannonictis is a genus of extinct mustelids. It is first known from the very Late Pliocene, and it survived until the end of the Villafranchian. The genus is most commonly recorded from deposits between 2.6 and 1.4 Ma. Fossil remains of Pannonictis have been found throughout Eurasia, from the Iberian Peninsula to eastern China.

Oligobunis is an extinct genus of mustelids, which existed during the Miocene epoch.
