Temnocyon is an extinct genus of amphicyonids endemic to North America. It lived from the Oligocene to Early Miocene approximately 30.8—20.4 mya, existing for about 11 million years.^[1]

The first fossils are recorded in North America at Logan Butte in the John Day beds of Oregon, in the Sharps Formation of the Wounded Knee area, South Dakota, and in the Gering Formation at Wildcat Ridge, Nebraska. 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]

-'''''Temnocyon''''' is an extinct [[genus]] of [[carnivorous]] [[mammals]] belonging to the family of [[Amphicyonidae]] ([[Bear-dog]]) endemic to [[North America]]  that lived during the [[Oligocene]] to [[Early Miocene]] approximately 30.3—20.6 [[Annum|mya]] existing approximately {{Mya|30.3-20.6|million years}}.<ref>[http://paleodb.org/cgi-bin/bridge.pl?action=checkTaxonInfo&taxon_no=41298&is_real_user=1 PaleoBiology Database: ''Temnocyon'', basic info]</ref>
-==Taxonomy==
-''Temnocyon'' was named by Cope (1879). Its type is Temnocyon altigenis. It was assigned to Amphicyonidae by Cope (1879) and Carroll (1988); and to Temnocyoninae by Hunt (1998).<ref>R. M. Hunt. 1998. Amphicyonidae. 196-227</ref>
-==Morphology==
-A single specimen was examined for by [[body mass]] by 	Legendre and Roth. It was estimated to have weighed {{Convert|21.3|kg|lb|abbr=on|sigfig=2}}.<ref>S. Legendre and C. Roth. 1988.
