If you have a quetz, it can be as easy as pie. You can pick them up out of water or off land with a quetz, just make sure it's head is facing away from your quetzs body. I grabbed one out of the swamp and another from the big red canyon with waterfalls in ragnarok near the huge bridge, then flew it to a ready made trap and dropped it in. Knocked it out, ready with kibble.
This dinosaur is a very intricate but interesting dinosaur to get. I did find it near the shore line as it had seen me and wanted to eat me. However I had 5 tranq arrows which you can get at lvl 21. I shot all 5 and he fell to the ground. Very good dinosaur to tame especially in the water. It beats anything in the water even with its stun strike. I recommend using this dino to fight. I have one named Juju. One like equals One love for Juju
These take around 8 kibble of Pachyrhino. Will take around 3 tranq darts from a longneck rifle. 4 or 5 minutes until tamed. I've tested this, Baryonyx is my favorite dinosaur. So I tested on what I'll need.
These things, as said, are incredible! They are good both on land and in the water, they are recommended for almost all the caves and only need simple fish meat to tame. A youtuber named Schwallbe has an insanely good one ( 10000 + hp 300 - 400 + atk. ) They are powerful, spawn singularly allowing you to tame it without dealing with others, and have, on brutal, high levels and lots of good stats to accompany it! Get one soon. Also, they can be bolaed, meaning you don’t really have to worry about getting hit! They take 5 - 7 arrows on easy, and yes, that may go up to something like 25 - 45 on brutal, but if we’re being honest, it’s worth the hustle.
