What use is force if you can't reach the target body (there aren't any studies to prove the steel-smashing thing either)? Any decent scale would show that T.rex's neck was taller than the Spino's wrists. Also, do read my point once more. Theropod arms weren't meant for gripping heavy objects.<quoted text>
More reasons spinosaurus would win:
1. It is possible that it could smash through steel, so it must be very strong, and Are you stupid?! Spino has huge arms! It would definitely be able to snap a trex's neck.
2. It had more teeth than t-Rex, so when it bit it there would be a lot more damage than if a trex bit the spinosaurus
You guys are all wrong and look stupid!
2. Pelecanimimus had 220 teeth, so it obviously had a stronger bite than any of the other theropods (sarcasm intended).
