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
Addition to my tip, I forgot to say that I play Mobile on Brutal difficulty that's why so many tranqs XD it slipped my mind. Dododex doesn't let you edit tips so had to make another. Sorry for confusion guys.
Don't listen to everyone stating you only need 5-7 tranq arrows. Bruh depending on the level you'll need more then a small amount. Honestly just in case I recommend 50+ asl long as you're taming high levels and not weak ones that are useless. Baryonyx are fast on land, faster in water. Their tail whip water attack stuns most creatures and if you raise up a baby and fully imprint you've got yourself an absolute land/water beast!
