Sthenictis campestris jaw

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:
