''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
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Car ...
. Out of the three
taxideine 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.
Description
''Chamitataxus'' is known only from a single holotype found in 1935, which consists of a nearly complete
skull. The holotype was discovered in a quarry not far from Lyden,
New Mexico, where the prehistoric
herbivore
A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage or marine algae, for the main component of its diet. As a result of their plant diet, herbivorous animals typically have mouthpart ...
''

rock formation
A rock formation is an isolated, scenic, or spectacular surface rock outcrop. Rock formations are usually the result of weathering and erosion sculpting the existing rock. The term ''rock formation'' can also refer to specific sediment ...
it was discovered in, the
Chamita Formation. Due to the relative lack of ''Chamitataxus'' specimens, much of the research into the genus is based upon research into better-represented taxa related to ''Chamitataxus'', such as ''
Taxidea'', the modern American badger, which also existed in the Late Miocene.
''Chamitataxus'' was fairly similar to its modern-day relatives in most respects; it was a
carnivore and judging from the skull found, it looked fairly similar. However, because so little of ''Chamitataxus'' has been found, estimating its size and other features is impossible; much is unknown about the genus. ''Chamitataxus'' had a very good sense of smell and had a firm grip like its modern equivalent and this enabled ''Chamitataxus'' to kill burrowing animals with a bite to the neck. Like other

s, ''Chamitataxus'' excelled at hearing low-frequency noises, which it could hear at a long distance. Overall, ''Chamitataxus'' was an expert hunter based on scientists' findings, and was able to prey on many different types of land-dwelling creatures during the Miocene.
