This may not help to some players but having a baby wyvern around lvl 75 can tame up to lvl 150 troodon (night only). I recommend putting the baby wyv on attacking target and have a shield out and let the troodon hit you and the baby at the same time. Once they kill the baby, you should have tamed at least one, possibly more troodon. You need to be lucky to tame more than one from a single feeding.
As much as i hate making a tip for this demon, put 3 dino gates down in a triangle and close them all. Put the troodon inside with a flyer or lead it in. Get a parge dinos about rex size. Maybe 2. Put it on neutral. Tranq it. Once tranqed use a tanky dino such as a carbonemys and stand near the rex. Release the troodon and let it attack your turtle while the rex slowly dies. If possible place 2 rexs asleep together to kill both at the same time.
