The Argentavis Ens Magnir

The argentavis ens magnir is currently believed to have had a wing span of anywhere from 16 to 26 feet, making it quite possibly the heaviest bird of all time. The biggest question here is, could this thing e know, they are real? We now terra torns did exist. Could they have met human beings at some point)? They were around when humans were aroundan it's possible that they interacted. And then austro lepithacus is the largest known primate ever. But there's no proof that early humans interacted with that creature.
