Wang et al., 1999
Microtomarctus is an extinct monospecific genus of the Borophaginae subfamily of canids native to North America. It lived during the Early to Middle Miocene, and existed for approximately . Fossil specimens have been found in Nebraska, coastal southeast Texas, California, New Mexico, Nevada and Colorado. It was an intermediate-size canid, and more predaceous than earlier borophagines.
Like some other borophagines it had powerful, bone-crushing jaws and teeth.
