Me and a friend of mine were arguing over if pre modern humans could deter and even kill a t-rex. I'd like your guy's opinion. Here are the rules - Humans can hunt in packs of 5 to 6 people. In extremely rare and thriving communities, up to 10 to 15. No modern day technology, guns, most weapons, even swords. Things they can use are stuff like long wooden spears, maybe rope. And for the communities that are really well off, very primitive bows. For the t-rex, well he's just a t-rex. At most there'd be a pack of 3, but usually they'd hunt alone. So go at it. The apex predator of the dinosaur period vs the apex predator of this era. Intelligence and adaptation vs strength, size, and maybe even speed. Who'd win in a fight?
If the early humans were to be surprised by the T-Rex, or or two would likely be killed while the rest escaped. Assuming that the humans had time to plan and prepare, the T-Rex would certainly lose. Early humans hunted mammoths, which were nearly as large as a Tyrannosaurus, likely stronger, and certainly faster. Recent computer models indicate that a T-Rex was unable to run, and had a top speed of about 12mph. Compare that to humans, who can easily break 20mph given proper physical conditioning. Some runners even run in excess of 25mph, which was previously calculated to be the T-Rex's top speed.
Plus, theyve found that t-rex's likely weren't primarily predators; but scavengers. But yeah, like Ridley said, a bunch of prehistoric humans with throwing spears could easily take on the t-rex much like with the mammoth
