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.
The best way to tame this guy is to craft a bola and throw it, (bola opens at lvl7) and it should be able to hold it until you knock it out. Feed with berries such as mejoberry and don't forget narcoberries if you dont have much in inventory, you need to keep it sleeping. And make sure to KEEP OTHER PETS AWAY, during the process! They may get in your way.
After that you can saddle it at lvl10. And its a good defense against dilophosaurs, bugs and other small dangers. :)
Every beginner should tame this dino because its pretty helpfull and its a very good mount and for its saddle you just need lvl 10 thats it and to tame get a bola and a wooden club first bola it then go to its head and hit it a couple of times and thats it its unconscious now put couple of mejoberries in its inventory and thats it you got yourself a good beginner's dino
