Super easy tame. Try to get one that's stuck on a tree or rock to keep it from running away. You have enough time to hand gather berries and narcoberries even if you have nothing when you knock it out.
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. (pls vote 🔼 to beginners see this)
