To tame this u will need: quetz, pelagornis (pelagornis has more health than pteranodon), extraordinary kibble, biotoxin and lots of it, a longneck rifle because a crossbow will kill the Griffin, flak armor because you will get hit a lot, and health brews. First build an argie taming pen on the quetz: a 2x6 foundation structure 4 foundations tall walls made entirely of double doorframes and one side having a dino gate, only also build a platform on the side for you to stand on. Next fly up to the griffin and have it aggro, now it should be circling and attacking the quetz, try to lure it in with the pelagornis, then let the pelagornis get killed while you close the gate. Do NOT move the quetz or the Griffin will clip out of the trap. Now stand on the side platform and shoot the griffin until it either falls asleep or is almost dead, if it has low hea lth wait some time because healing it with a owl will make it fall out of the trap. Sorry out of writing space now.
