Medieval Lord Threatened by Tyrannosaurus!

Plus, mammoths weren’t fast, agile, apex predators that could dismember men and horses with ease.

I agree that lances and the like could penetrate dinosaur flesh, and you could potentially injure it badly enough that it might die eventually. But, I’m talking about a clean kill that would give the knight some chance of survival. It took early whale hunters hours to bring in a whale, and the only reason that even worked is because the whale generally didn’t fight back, opting to flee. It would die due to exhaustion and blood loss. It wouldn’t work that way with a T. Rex. The T. Rex would lay waste to anything near it before succumbing. Think of a Tyrannosaur’s stance and movement. Unless you caught it totally by surprise (on a charging horse, not likely) there’s not much chance it would leave its belly exposed. They certainly had to be adept at protecting that region considering some of its prey used exactly that defensive tactic. To survive a direct assault, you’d get one shot at it. The odds are exceedingly slim that a horse-mounted knight could deliver a clean kill in one pass.

Build a picket field of upraised sharpened wooden pikes.

Holding a rope, with an agile charger (what’s a charger, anyway?) repeatedly run rings around the beast’s legs. Or, perhaps only one circuit is necessary. Beast falls on spikes; finish it off, if necessary.

Or just skip the spikes. The beast on its back is helpless, I think. Even on its side.

And the rope circling thing would be all the more easier because I don’t think the beast’s field of view doesn’t even cover those areas, and it certainly is not a twinkle toes.

Ooh, I like the rope idea. I saw a documentary once where some dinosaur hunters were using that tactic. Except that the dinosaurs were big four-legged combat walkers, and the horses were made of metal and flew.

That footage was faked. Everyone knows that four-legged combat dinosaurs were cold blooded and couldn’t live in snow.

Anyway, I stole the idea from some Irishman. And yes, but in my scenario the knight gets the hairy headphones.
