T-Rex teeth are designed in a way that they can tear meat but are also made to hold them, and then they twist their mouth and that's what tears the meat off. The teeth themselves aren't designed to specifically puncture, thus one bite without the head wrenching wouldn't be extremely deep anyway. The tail ends in only one very long needle-like end that is designed to specially poke holes, and is moved with enough force to be almost a blur, meaning there's a lot of driving force behind it.
Those teeth are specially designed to slice through flesh, they even come with their own serrated edges to make slicing large chunks of flesh (and bone) easier. Kong took it, no problem.
I'm not doubting her tail's sharpness, as it goes through people and Predators with ease, just that it's particularly small compared to an opponent of Kong's size/weight and won' be as lethal.
Just watched he Kong/T-Rex fight scene, he not only picks up and slams a T-Rex with just one arm, he picks up a rock that probably doesn't weigh much less than the queen with just one arm. The Queen would be puddy in his hands.
Put 3-4 T-Rexs against the queen, she stabs (kills?) one via tail and then the other 2-3 come in and chomp her to death, despite dying themselves from the acid-blood. She doesn't have anything close to the agilty and fighting savvy Kong displayed in that scene.
