Your best bet at taming one of these is to build a small pit-fall nearby and lead it inside (Baryonyx are very fast, so make sure you can outrun it. Otherwise, a Pteranodon may do the trick.) Use a crossbow and tranq arrows to knock it out. They are pescatarians, so make sure you have plenty of fish meat to tame them, but keep in mind that this will take much longer than other methods. It is highly recommended to use their prefered kibble, however it may not be readily available. Prime fish also does the trick pretty well, which is relatively easy to farm off of Coelacanth and Sabertooth Salmon with the metal sickle.

Once tamed, a Baryonyx will absolutely change the way you play the early/mid-game. They are amazing swimmers, lack an oxygen stat (they can stay underwater indefinitely) and have a tail-whip ability that can stun nearby enemies underwater, making them great for exploring the oceans without fear of a megalodon attack. Unfortunately, without any levels in your own oxygen stat, you won't be able to ride them for very long underwater before beginning to suffocate. They harvest a lot of fish meat and some biotoxin, which can help with taming other dinos.

they are pretty easy to knockout just dont go to the water with them they can stun you there, build a trap dont try to shoot it and run they are very fast in land, build a trap first,shoot it run to the trap,your trap must have a door frame so you can get out they cant fit through it just start shooting it with tranq arrow or dart feed them raw fish meat if you want it faster feed it prime fish meat or pachy kibble

I was taming a lvl 130.i was lvl 50 with 300 health.i tried bringing it into pen but failed twice.so I risked it .just stood there shooting it in the face and it barely reduced my health.pachyrhino kibble gave 12% taming without soothing balm.with minor (3x) balm prime fish 6%, fish meat 2%.

1.make a trap made out of wood or stone wall( you can bola them to)

2. Use tranquilizers arrow or just bola

3. Tame it raw fish meat and narcotics if the taming process is too long.

4. Unlock the saddle at level 49 and with 24 engram point).

5. Enjoy your time with baryonx( they have the stun ability in water).

Ok so I understand that people have a hard time taming these but cmon throw a dodo and put a bear trap on the ground keep some chain bolas at least 20 tranqs and that’s for a high level. I tamed Rudy (my bary) with 3 arrows and a dodo but it was level 7 🤔.BEST FOR CAVES and I caught Rudy in the bay of south zone 1.

Also great for underwater exploration!
