One way to tame without traps or rare flowers

Get a beelzebufo, chase it down and hit it. Best way to keep up with procoptodon. It was moving fast but beelzebufo covers it with a jump. Just did it a few minutes ago

It ran from near smugglers peak to a river side and fell unconscious, it was a safe spot with only 3 raptors busy fighting trikes at that moment at some distance. With rare mushrooms and waiting a few minutes I had it tamed.

It was fun!!! Chasing!!!

Don't forget rare mushroom and some narcotics.
