The Actual easiest and best way to tame one. Is pick it up with a skiff and use whatever you want on it, a frog, scorpion, clubs even. The skiff will hold it helpless forever. You can carry it back to the safety of your base first even.

I know this is not a beginner tip. But it is the easiest way

The skiff works on pretty much anything you could want to tame. Especially quetz and griffins.

It cannot pick up managarmrs or gigas or elementals.
