Load up metal dino gates (roughly five), have a pararacer with the platform for a sturdy base for your cannon (the rockets no longer deal torpor), line up the gates with the paracer out of punching range, and finally have your buddy kite him to back of your paracer and be ready to take stone throws as you belt him from your cannon.(Be sure to unload three cannons after every stone) Once you get him dropped starve him out and load on your kibble. You'll be taming 150's before you know it!
It's a bit silly that kibble tames it a lot better than rocks or sulfur because even in the dossier it says that it lives off of absorbing nearby rocks and minerals. So mabey they should make it so you have to feed them a rare mineral like obsidian what if they made it so you could tame one fast and with high effectiveness by giving one a few hundred or few thousand obsidian . or what if there kibble was made out of a combination of ores and minerals .
