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.
At lvl 72 with flak armor on, a lvl 5 Troodon knocked me out with one attack at night. Last thing I saw was those glowing eyes before passing out. My Guess is that they attack vital organs. Luckily my Doedicarus was up for a game of baseball and launched that little devil out into the stands.
