Sthenictis is an extinct genus in the weasel family (mustelids) endemic to North America and Asia during the Miocene epoch living from ~13.5—9.2 Ma (AEO) existing for approximately 4.3 million years.
Taxonomy
Sthenictis was named by Peterson (1910). It was assigned to Mustelidae by Peterson (1910) and Carroll (1988); and to Ischyrictini by Baskin (1998).
Morphology
Two specimens were examined for body mass by Legendre and Roth[1] 1988:
- Specimen 1 weighed an estimated 13.7 kg (30 lb)
- Specimen 2 weighed an estimated 5.98 kg (13 lb)
Fossil distribution
The oldest specimen was uncovered at Black Butte, Malheur County, Oregon.[2] Other locations are: Quatal Canyon, Ventura County, California, Kleinfelder Farm, Saskatchewan, Canada, Nebraska, Texas, Florida and in Inner Mongolia, in China.[3]
