To tame the Carcharodontosaurus, you have to trap it otherwise it will kill you. Once you trap it, feed it dead dino corpses like Woolly Rhinos, Carnotaurus, etc. Once you do that, a taming bar will appear above it, your objective is it fill it up. Once you fill the taming bar up, it will turn green and you have the ability to ride it. There will be another taming bar on the bottom of your screen. You haven’t tamed it yet, once you ride it you have approximately 600.0 seconds to ride it and you’ll have to kill dino’s while riding it. Once you fill the taming bar, it will dismount you and it will tame.
