Agriotherium is an extinct genus of bears whose fossils are found in Miocene through Pleistocene-aged strata of North America, Europe, Africa, and Asia. This long-lived genus persisted from at least ~11.6–2.5 Mya.[2] Materials from the late-surviving A. africanum in Africa have suggested that A. africanum died out during the early Gelasian
