I once saw an old film of Kalihari Bushmen hunting a giraffe. They worked together to distract the giraffe so that one guy got in a position to wound it (with a spear in that case, I barely recall), then they tracked it for three days and caught up to it when it died. I don't remember much after that, but I think the rest of the tribe relocated to the kill.
A fire-wall could be used to bring your megafauna prey to you first, or to corner it, and then to prevent it from running too far away while you play the Komodo dragon waiting game.
The San tribe of the Kalihari still hunts big game with poisoned arrows, probably not unlike people did 50,000 years ago:
The ramifications of a tribe wounding and/or poisoning big game and then relocating to the position where the animal died may be quite important. The 'ologists may be spending a lot of their time looking for
logical placement of settlements, when those settlements may have actually been semi-randomly positioned according to where some giant critter finally keeled over.
