There’s two ways to tame one of these. Either hit it and run after it until it gets stuck on a tree or a rock, then KO it, or bola it and knock it out. Both ways once it’s knocked out just put berries in its inventory and it should be good. Although it won’t follow u unless you put a saddle on it. Ur welcome
Are you a new Ark player? A Tipp for you. He is fast... faster than you. The best way is craft Bola and Bola the Parasaur. Knock out and feed it with Berries. Dont miss nacoberries... Good you tamed it! Craft a Parasaur saddle and ride it! Good luck.
