                                @daniel owens From Nat Geo: Truth: Hyenas are opportunistic eaters—but also accomplished hunters, alone and in groups, Benson-Amram says. Part of this perception comes from people watching hyenas and lions fighting over a carcass.

                              It amazes me that scientists think they know what any number of years looks like past the earliest confirmed record of man. Which, I'm assuming, is not much over 10,000. Ha. "Millions of years"

                                              Bone crushing dogs and cats that are just like them but better, dangerous enough to kill the most fearsome of animals.
