So I just now got one unconious, but I did it in the forest/big trees ( heavly populated with them ) and I went on top of a hill in the forest and used a crossbow with tranquilzer arrows, I would really suggest you use it, and just put some meat in it and some narcoberrys and you should be good to go. If it's a high level it will be really difficult.

How to tame a carno:

1. Get a carbonemys, preferably one with a lot of health if the carno is high level

2. Get some tranq arrows and a crossbow, then equip the crossbow in your hotbar

3. Mount the carbo then find a carno

4. Equip the crossbow while you are on the carbo then start shooting at the carno

5. Just keep shooting at it with your crossbow while your carbo tanks the damage until the carno starts running away which if you are lucky your carbo will be left at half health

6. Dismount from your carbo and start chasing after the carno while still shooting it until it falls unconscious

7. Feed it meat until it tames while watching its torpor.

You can actually tame a Carno pretty easily if you have the right items in Ark: survival evolved (at least on the Nintendo switch). The items I used are:

1-crossbow

2-narcotic arrows

3-raw meat

4- Beelzebuffo

Step one

Mount your Beelzebuffo and shoot the Carno with your crossbow and narcotic arrows from a good distance away

Step two

Jump away from the Carno about two times on your Beelzebuffo and turn and shoot it

Step three

Repeat step two until Carno is knocked out

Step four

But raw meat in the Carno’s inventory and wait for it to tame

Hope this helps! -Even Steven

Search for a raptor, and find out you can’t find one when you want to. Spot carno on the way. Get bow and tranq arrows, and shoot at the thing until it falls. Forget the stuff to keep it knocked out. Feed it meat, preferably regular to make it hard on yourself, realize that it is going to wake up. Collect berries. Force feed knockout berries. Realize it is taking too long. Tame other small animals (I did a patchy, iguanadon, and two dimorphs. Then you have a tamed carno. Bring prime meat if you do not want to collect berries (you will not get the full experience of realizing you forgot to bring any knockout things).

Well when I started my world in my mobile I was just wandering around the lava cave and saw a rex and hide behind a rock and then this motherf@##*r came by jumping off a cliff behind me and start fighting that rex for no reason and after sometime when I built my base I went to collect resources and when I was coming back a sarco coming to eat me but this motherf*#@#r was in front of me then both of them starts killing each other and I ran by side of them

Carnos are good carnivores that aren't that hard to tame! They are fast, tanky, and do alot of damage! They don't take up that fast then other dinos and are not hard to find!

I recommend going to either carno island or beaches that are close to a forest, and are really easy to trap!
