If taming, its easiest to either tame on outskirts like everyone else said or take a fast, leveled up dino with you for protection. I used my rex I tamed right before it and I had my argentavis to take him home. They keep up rather well unless you're going through a jungle. Shoot it in its trunk for easiest ko (I used darts. On a low level mammoth it can take 2 darts with the rifle to take em down easily)

I need help how to tame it I don’t know how

Do not I repeat do not try to tame a mammoth when you are near a Rex spawn area. like for the two that I lost

If you put a cloth hat on it it looks like a bandanna

None of the ones I KOed were hard to take down and the one that lived wasn't that hard to tame. The issue is predators, I think the game gives sabertooth and direwolf ai a way of sensing a down mammoth. It took me three times to finally get one 🫠

I bagged a tickle chicken, spino and 2 rexes before I finally tamed one of these guys.

Find one in Asgard and get it stuck punch it with your friend if you have not friends (I’m talking to you) your skrewed
