>>13540780HUman intelligence allows them to do something even raptors could not see coming and are unprepared for: set traps. For many dinos even just a pulled stumble rope would have been a death sentence. But because of probable lack of ropes strong enough any other kind of trap to make them stumble would work, for example a good old classic covered hole. Dino comes running, dino leg falls into the trap, dino momentum pushes body further, dino falls down and dino leg probably breaks. Tribe dine good that night.
Man has no chance against them directly, but he can use preparation and cunning.
