Microtomarctus

Microtomarctus is an extinct monospecific genus of the Borophaginae subfamily of canids native to North America. It lived during the Early to Middle Miocene,[1] and existed for approximately 7 million years . 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.[2]
