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
Bringing a simple raft cage to the swamp should allow you to easily trap and transport this guy to an appropriate area to knockout and tame.
For some reason (bug?) you can’t be damaged while driving the raft, even when this guy is standing on top of you! (PC)
Extremely useful, find them near almost any river bank. Lure them out of the water (do NOT try to fight them in the water, you will 100% die) and bola them. Then either knock them out with a few hits or hit it with a tranq arrow. We use them as protection when traveling, and they have takes out everything from a pack of raptors to a therinosaurus to carnos.
