Bears (ursidae) appear in the fossil record during the middle Oligocene and are part of the suborder Caniformia (doglike carnivoran). They are hypocarnivores, meaning they are not strictly meat-eating. This is reflected in their dentition; large canines, large flat molars and poorly developed carnassial teeth. Features of the bear skull include reduced sagittal crests and heavy zygomata, a characteristic of omnivores.
