Use a tranq darts with a longneck rifle and aim for the head. The headshots do way more damage. When taming this dino pay very close attention to its torpore timer. It has about a 3 and a half minutes of torpor. Use demetrodon kibble for the highest level, but crops or mejoberryies is good as well. If you want a very quick tame lookup on youtube a really cool stimberry trick (Look up Ark Stimberry Taming). This trick is good if you want a fast taming dino, but its difficult to do with this dino because of its little torpor timer.
Sewing a lot of ppl having a hard time finding a lone one, that is not being murdered by predators. Well, I know where two good spots are. First, outside hidden lake, directly south outside, on the beach, in front of the little beach, around those rocks, usually one to three will spawn, but usually just two. Over near the ruins in redwoods, where the water fall is, there is ually about twelve, and very little terror birds, but look out for the bears. I have no problem taming, knocking out, and hunting them, just be cautious. And I advise using the biotoxin. Helps a lot. Thanks! Also, when looking for *any* creature, like at all, I advise using da frogs. They are very helpful..
