''Phlaocyon mariae'' is an extinct species of the genus ''Phlaocyon'', belonging to the subfamily Borophaginae and tribe Phlaocyonini, a canid which inhabited central western North America from the Miocene living 20.6—16.3 Ma, and existed for approximately . ''Phlaocyon mariae'' was described and named by , the name honours S. Marie Skinner who assembled and documented specimens from Nebraska. The species is known from worn upper and lower teeth and skull fragments found at the Early Hemingfordian ''Aletomeryx'' Quarry Site, Runningwater Formation, Cherry County, Nebraska. ''P. mariae'' is the largest ''Phlaocyon'' with teeth that display a mixture of hypo- and hypercarnivorous characters. Wang et al. noted that the poor preservation of ''P. mariae'' makes it difficult to assess its relationship within ''Phlaocyon'', but, based on a cladistic analysis, concluded that ''P. mariae'' is one of the more derived species together with ''P. yatkolai'' and that these two species are the first and earliest borophagine to evolve hypercarnivory.〔 ==References==
