Pachycynodon is an extinct genus ofarctoid belonging to the familyAmphicynodontidae. It lived inEurope during the lateOligocene epoch.[1] They were relatively small carnivores. They have deepmandibles that are robust, even more robust than that of genusAmphicynodon. Theirmuzzle is elongated.[2]
The genus is part of an extinct family ofarctoids known asAmphicynodontidae. Genus Pachycyanodon contains several possible species and subspecies with thetype species being Pachycynodon crassirostris. A list of species is found below and further info about some of them are found below that:[2][3]
The type species of this genus, it was described by Schlosser in 1888 through a single isolatedfourth metacarpal bone. It was found in theQuercy phosphorites but from an unknown locality.[3]
It was a large species, possibly one of the largestcarnivoran from the Quercy phosphorites. Filhol described this species in 1876.[3]
The holotype of this species was uncovered inSouth Dakota inPorcupine creek in the lowerRosebud beds. The holotype specimen is a small lower jaw that is nearly identical to Pachycynodon tenuis only differing with the teeth of P. delicatus belong slightly longer.Pachycynodonharlowi is also nearly identical to both differing in the M2 and M3 molars being larger and a slightly shorter series ofpremolars.[2]
It was described in the year 1882 by Filhol. The species name "dubius" is from Filhol doubting that it belonged in genusCynodictis based on its groupedtrigonid of M1.[3]
It was also described by Schlosser in the year 1888 however there was nobiostratigraphic locality given.[3]
It was described in the year 1915 by Teilhard. It is considered by Teilhard to be a model for the origin of this genus due to its small size.[3]
