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. :)
