Temnocyoninae
The Temnocyoninae are an extinct subfamily of medium-sized bear dogs endemic to North America that lived during the Early Oligocene to Early Miocene about 30.8-20.43 million years ago (Mya) existing for around 10 million years.[1]

Fossil distribution
The first fossils are recorded in North America at Logan Butte in the John Day beds of Oregon 29–29.5 Mya, in the Sharps Formation of the Wounded Knee area, South Dakota 28–29.5 Mya, and in the Gering Formation at Wildcat Ridge, Nebraska 28.3 Mya. These early temnocyonines attained the size of coyotes or small wolves (15–30 kg), and are identified by a uniquely specialized dentition. The last documented occurrences of temnocyonines are found in sediments in northwest Nebraska and southeastern Wyoming.[2]
gollark: git.osmarks.net is all.
gollark: Update: I have decided fossil is neat but not enough for me to take any action based on this. All Fossil-related migration projects are now halted forever.
gollark: Perhaps I should migrate my projects to fossil now, so they get 0 (zero) users.
gollark: Yep. I just resolved it. It needs SCRIPT_NAME to be "" and not "/".
gollark: But it has repos. And it worked when I switched it to use HTTP.
