Pharsophorus is an extinct genus of borhyaenoid sparassodont that inhabited South America during the mid-to-late Oligocene epoch. Originally, Pharsophorus was though to be a borhyaenid, and was even considered to be the direct ancestor of Borhyaena, Acrocyon, and Arctodictis, but later phylogenetic analyses have shown that it is not a member of the Borhyaenidae and is only more distantly related to these forms.^[1]^[2] Remains of Pharsophorus are known from the provinces of Mendoza, Santa Cruz, and Chubut in Argentina, as well as the fossil site of Salla in western Bolivia.^[3]^[4]
