Best way to tame an argie is to have a taming cage on your raft. You build it by making a two foundation alley with ceiling, doorframes, and two Dino gates. Lead the argie with you pteronadon. Once lined up, you need to close the second Dino gate once the argie entered the first gate. Then go around and close the first Dino gate. Then you traq it through the doorframes. Once knocked out, you are free from any wild Dino's since you are in the middle of the ocean.
