Then again, the same suite of features could have just as readily been employed to dismember carcasses or crunch tough plants, and some researchers have argued that Agriotherium, Arctodus, and similar bears were omnivores that often fed on carrion rather than chasing down large prey. The hypothesis that giant short-faced bears of the genera Agriotherium and Arctodus were primarily carnivorous and preyed on large terrestrial mammals is examined. There is no Arctotherium in that study. Of all the bears to come and go during the group’s 23 million year old history, none had a bite more powerful than Agriotherium africanum – a ursid as large as today’s grizzly and polar bears that roamed Africa during the latest Miocene and earliest Pliocene epochs.
