You wanna tame a quetzel? (In mobile tho)

If you want it saddle and you need to be lvl 71

Try to do the "hunt argentavis quest"

Finding one of this is rare but u can find it near the red obelisk taming it u need a pteranodon because its faster then the argentavis becase i tried taming one of this with an argentavis on mobile and if your too far away from quetzel(due to non-stop hitting it with an tranq darts)it will fly away in the distant that your argy wont follow it anymore
