Agriotherium.

Agriotherium, an extinct family of bear animals, once flourished in the early Miocene-Pleistocene, has been found in Eurasia, Africa and North America. According to the mainstream taxonomy, suburban bears have long been separated from the common ancestors of Ursidae. These guys should be an independent subfamily of Agriotheriinae among Ursidae, so they are not closely related to any modern bear. Although not well known among the public, the suburban bear is indeed a very powerful beast. The African suburban bear (agriotherium africanum) is comparable to the modern polar bear in size, while the agriotherium schneideri found in Mexico may have a skull length of more than 50 centimeters and a weight of more than a ton, which is no less than the short-faced North American bear found in the late Pleistocene. Tectonically, suburban bears differ greatly from most omnivorous "traditional bears" – they have shorter backs and long limbs, narrow skulls and cleft teeth that resemble canines. These features suggest that suburban bears should be highly carnivorous, and that they should be the killers of many large ungulates at the time of their existence, as well as others. Carnivores hate bony predators.(Figure 9 is a bear-to-bear confrontation with a half-saber-toothed tiger in the African suburbs)
