Perhaps the exhibits should include depictions of “buffalo jumps”. Prior to the introduction of horses in North America by the Spanish, native peoples sometimes resorted to causing herds of buffaloes to stampede and diverted the paniced herd to high bluffs or cliffs where large numbers would fall to their deaths and then be butchered on the spot by the natives. There are several sites in North America where this frequently occurred.
The same kind of massacres were used on horses and mammoths both in ancient America and Europe.
