Tomarctus is a canid genus of the extinct subfamily Borophaginae which inhabited most of North America during the late Early Miocene to the Early Barstovian age of the Middle Miocene (23—16 million years ago).

Nov 18, 2014 · Tomarctus is known to have existed for at least the first half of the Miocene,‭ ‬and seems to have disappeared with the appearance of later borophagine forms like Aelurodon.‭ ‬During the early half of the Miocene Tomarctus would have lived amongst other groups of carnivores such as false sabre-toothed cats,‭ ‬bear dogs and entelodonts.

These include the most hypercarnivorous borophagine Euoplocyon, the peculiarly trenchant Psalidocyon, and the dwarf lineage Microtomarctus. The next clade, Aelurodontina, is the first major hypercarnivorous group and is represented by Tomarctus and Aelurodon in the Barstovian and Clarendonian.

Tomarctus is a carnivorous canine-like animal which lived approximately 15 million years ago during the Middle Miocene Period. It was first discovered during the 19th century and was named by Edward Drinker Cope in 1873. Its name means “cut bear.”

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.
