***Martinogale*** is an extinct genus of [skunk](/source/Skunk) from the [Late Miocene](/source/Late_Miocene) of central [North America](/source/North_America).[1] There exist three accepted species, *M.* *alveodens*, *M.chisoensis* and *M.* *faulli*, which may have overlapped in range but occupied somewhat distinct moments of the Late Miocene.[1][2][3] As well as the dubious *Martinogale? nambiana*.

## Description and species

***Martinogale***, as happens with most fossil skunks, has been solely described off of fragmentary craneal remains. The genus is mainly characterized by its jaws: in the upper jaw there's an absent upper Molar^2, and greatly enlarged but thin upper Premolar^4 and Molar^1; while the lower jaw has a small and forward P^2, the absence of a lingual or labial cingulum around the P^4 and a well developed M^1; neither jaw has a present Premolar^1. In regards to skull morphology, it is smoother and narrower than in living skunks, with a large, flask-shaped [basicranial bulla](/source/Basicranium).[1][3]

### *Martinogale alveodens*

This species was described in 1930 as a small mustelid from a fragmentary lower jaw found in the Edson Quarry, from late [Hemphillian](/source/Hemphillian) [Kansas](/source/Kansas). It was described as the type of the new genus. Due to its fragmentary nature, the placement of *Martinogale* within [Mustelidae](/source/Mustelidae) was uncertain, but seemed feasible due to some similarities to the earlier *Martes nambianus*.[1] In 1938, a better preserved jaw indicated similarities with the [spotted skunks](/source/Spotted_skunk) of [Mephitidae](/source/Mephitidae).[4] The species name, *alveodens*, hails from [Latin](/source/Latin) *alveus*, “a hollow, cavity or channel" and *dens*, "tooth"

### *Martinogale chisoensis*

The largest species, *M. chisoensis* hails from the early Hemphillian Crew Bean Local, it was described in 2003 based on a rather complete skull. Due to the cranial similarities with *[Buisnictis](/source/Buisnictis)* it was named *"Buisnictis" chisoensis*.[2] In 2005, along with the description of *M. faulli*, it was reassigned to *Martinogale*.[3] The species name, *chisoensis*, comes from [Chisos Mountains](/source/Chisos_Mountains) in [Big Bend National Park](/source/Big_Bend_National_Park), [Texas](/source/Texas), and *ensis*, Latin for “from”.

### *Martinogale faulli*

The oldest and smallest of the species, *M. faulli* was described in 2005 from a partial skull found in the Late [Clarendonian](/source/Clarendonian) [Dove Spring Formation](/source/Dove_Spring_Formation), from Kern County, California.[3] *M. faulli* has a smoother skull than *M. chisoensis* and relatively smaller teeth, with a better defined basicranial bulla.[3] The species name *faulli* is in honor of Mark Faull, a former ranger at [Red Rock Canyon State Park](/source/Red_Rock_Canyon_State_Park_(California)).

### *Martinogale? nambiana*

In 1874, a P^3, P^4and an incredibly fragmentary M^1were discovered in the Santa Fé Marls, New Mexico. Cope originally identified it as *Martes nambianus*,[5] uncertain of this association, a year later Cope moved it to *Mustela nambiana*.[6] When Hall erected *Martinogale,* he moved *M. nambiana* into his new genus, where it has since remained.[1] In 2005, Wang et. al. argued that the few characteristics present in these teeth were too non-specific, arguing that they simply represent the basal mustelid condition and that *M? nambiana* should not be considered a part of *Martinogale*; that the specimen can't be ascribed to a concrete genus.[3]

## Phylogeny

When compared to modern genera, both extant: *[Spilogale](/source/Spotted_skunk)*, *[Mephitis](/source/Mephitis_(genus))* and *[Conepatus](/source/Hog-nosed_skunk)*, as well as extinct: *[Brachyprotoma](/source/Brachyprotoma)* and *[Osmotherium](/source/Osmotherium)*, *Martinogale* presents reasonable differences in the premolar structure, thin postorbital skull, slightly expanded [mastoid process](/source/Mastoid_part_of_the_temporal_bone) and the general structure of the [basicranial bulla](/source/Basicranium).[1] In 2005 Wang et al.'s phylogenetic analysis recovered *Martinogale* as a somewhat paraphyletic association, although as their chronology advances so does their derivation:[3]
