You will usually find a parasaur in a forest or by the sea these animals are intelangent you might never want to put in on wandering unless you put it in a pen so it does not get away knock a lvl 5 or lvl 6 out it is good to start with this lvl
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.
