You have to get a pterodon to tame this creature. Once you do for a high level you will need a trap and for a low level you can just run around and shoot it with your crossbow. For the trap you need at least four regular stone Dino gates and two doors. Then you just place them in a line facing eachother and place a door on either end of the line. Then leave one door closed and lead your argy in though one door and run out of there and close the other door behind your fast. They also have very low torpor so you can knock them out fairly quick.
