Hi there whoever reads this don’t try it. Ok so I was just flying around on my pterodactyl when I saw a Rex I got my trans arrows landed on the ground and then saw an alpha rapter nearby so I knocked out the Rex but I got 1 hit away from death so I put the food and narcotics in and kept a eye on the raptor and then it was tamed like 30 minutes later it wqas tamed. It was crazy remember always check the place for any alphas and make sure there’s a cliff if your gonna tame a Rex
