There's a fossil of a t-rex that's believed to have been very old when it died (like, 28ish). It had evidence of injuries all over it, including having been stabbed through the back of the skull and into the brain by another T-rex's tooth (the scar was old and healed, so it survived being bitten in the brain)

I wouldn't bet on anything but a long drawn out campaign against it

I like the ideas here but I fail to see where you guys get the spears from. We only get a knife and food, which presumably doesn't come with a long stick.

I have a month, a place to avoid retaliation, the target can't run away or effectively hide, and no creature in its entire evolutionary history has ever seen a ranged attack before. Each time I hit it, it weakens snd slows as it bleeds, expends energy, and fights infection.

I like my odds with the sleepytime atlatl poo-spear better than being 1 of 20 guys trying to peel a mammoth off from a herd in random terrain.

I'd assume they're more like a flightless bird, like an emu. Those get on perfectly fine with just two legs and a long neck, and some of the recently extinct flightless bird species seem pretty terrifying at just a couple hundred kg.

I don't care if is has feathers, or long grabby arms, I'm waiting for it to fall asleep, and chucking a spear at it, and running, every single time until it dies of bloodloss, gangrene, or exhaustion.

Does the T Rex even understand what I did? Ranged attacks didn't exist for 65 million years after it went extinct, does something that evolved to hunt slow, armored herbivores have any response to ranged hit and runs? The many species of megafauna humans hunted to extinction before the invention of writing suggests no.
