I was never a fan of traps. Once i reached the right level for unlocking crossbow the first thing that came to mind. Therizino. I found an open field with no other dangers nearby. I saw his level and got far enough to shoot him before he shreds me to pieces. 10 tranq arrows did their job. He is down, put a soothing balm 3x. Use the 200narcotics keep him down. Spam the mejoberries and wait. With my trusty Pteranodon protecting us from dilos and raptors after 40 minutes he was all ready to go. I have never used traps and never will. My next tames will probably be a male Rex and a female Therizino for my tamed beasts.
