Indarctos is a genus of mammals of the bear family Ursidae, endemic to North America, Europe, Africa, and Asia during the Miocene. It was present from ~11.1 to 5.3 Ma, existing for approximately 6.2 million years.
The oldest member is from Arizona (~11.1â"7.7 Ma) and youngest is (~9.0â"5.3 Ma) from Kazakhstan. In North America this animal was contemporary with Plionarctos (~10.3â"3.3 Ma).
Indarctos was named by Pilgrim (1913) Its type is Indarctos salmontanus. It was assigned to Agriotheriini by Chorn and Hoffman (1978); to Ursavini by Hunt (1998); and to Ursidae by Pilgrim (1913), Carroll (1988) and Salesa et al. (2006).
