Just saying if you trap the Carchar it can sometimes bug out and not eat the corpses you give it then you have to go out of render of it and back in to make the glitch stop. I tame a Carchar by getting a really tanky tame then whistle passive then let the Carchar attack it while you get the corpses if you didn’t cryo one of your tamed creatures and threw them out already then you just feed the Carchar withought it lagging. This is how I tamed my first Carchar so I hope this helps and I know it’s rather late to type this but I just thought why not.

In order to tame it, you need to kill and bring Dino corpses to it(it will do a sniffing animation). It will then feast on the corpse and you will see a friendship meter, bring dead dinosaurs to it in order to fill up that meter. Once full, you will have a max of 10 minutes to ride the Carcharadontasaurus and kill all dinosaurs in site in order to raise it's taming bar, just know it loses slight taming effectiveness when taking damage from dinosaurs, it loses a great amount of effectiveness when you get thrown off, if this happens, simply just do back the first step until the meter is full again. It has a bite which induces a thrash effect which slows down healing, it's second ability is a tail swipe or spin. Good luck.

First step: Trap in large bear trap to make this easier, drag over and offer it dead dinos.

Second step: Jump on and make it eat all the things.

This will probably be a new go to creature

Just as a tip for the second stage I would recommend unclaimed diplos since they don’t do damage you won’t be at risk of losing that precious taming effectiveness as well as that they give a lot in that second stage!

Feed it gallys that’s all I can say

If you trap one feed it 1 baby yuty because they give full friendship then ride it and things that attack back will ruin taming effectiveness and baby wyverns are best for taming it up. I hope you enjoy your new friend

DIPLODOCUS are the best for finishing stage 2 of taming, because the effectiveness is based of LEVELED HEALTH ~ Obito Uchiha

This is actually deceptively easy to tame if you do a little setup. You will need of creatures with super high health you don't mind losing (cryopodded), a baby yutyrannus(cryopodded), a large bear trap or two, and 4 metal dinosaur gateways. Once you find your carch, place down 3 of the gates in a \_| shape, with the opening facing your carch. Place your bear trap(s) inside. After that lead the carch into your trap, preferably with something that's fast and can take hits. Once it's in the bear traps, place a final dino gate completing the square. Once that's done, put all your carnivorous creatures on passive, and slaughter the baby yutyrannus. Drag it's corpse over to the carch wich should sniff the air and then eat it. Beware of argentavis, as they will steal the corpse. Once it has eaten the corpse, the carch will temporarily become ridable. Dismantle one side of the trap and walk it out. Next, you'll want to uncryo your high health tame and make sure it is cryo-sleeping. Once it is, unclaim it and then mount the carch and eat it. Repeat the past two steps until your carch is tamed.

The trust part of taming goes by drag weight. A rex will give it 100% trust, Yuty is 75%, Stego and Trike are 50%. On the killing part of the taming it goes by XP. So higher level and bigger dinos tame faster. Just avoid taking too much damage and roar at 99 kills or it will kick you off and have to do friendship again. Good luck and hope this helps.

THEY ARE VERY POWERFULL

Cage them and then ride them after you kill stuff and have it eat that

From experience: If you don't fill the trust bar in one feed the Carchar WILL aggro on you. Have a flier ready! These don't do well trapped. Once it sniffs the body/notices your offer, drop the body and book it back to your flier.

Here's a little tip, whatever you do DON'T try to tame a carcha on fjordur if you don't want your roitine for the next irl week to be boot up ark and fly around 3 spots with no effect. Try. On ragnarok or the island instead

Beware when taming a high level you will probably need to gain their trust multiple times it took me 3 tries

If you've got one trapped, and it sniffs but doesn't eat, for whatever reason it doesn't like being trapped??? (Imagine that). You can try leaving the area, and letting it re-render but it may not work. My tribe and I ended up having to let it out of the trap, leaving to let everything re-render, and dragging corpses over to it (while it was running around free - so yes, mildly terrifying), then proceeding with the tame.

Pro-tip for feeding: one of the tribe guys is obsessed with breeding and mutations so we had some very OP rexes. We just cryoed abunch of babies, let it out (with cryosickness is easier), unclaimed and killed it, and it literally only took 1 baby rex to let us start riding. Then repeat to let the Carch eat the corpses while you ride, and viola. Your very own spikey giga.

Depending on the server, you can also use baby rexes or spinos to tame one (bringing up it's trust) that can make it go full or most of the way (again depending on the rates) so it'll be much faster then. Just make sure ya trap it 1st

Hope this helps!!!

Can take it in boss fights ?

With high level army

Alright so what I used for my 145 charcar was 2 trikes and the trust was full. P. S. Trikes give a little over half trust

My taming Method:

1. Trap him

2. Kill any Dino and carry it to him

3. Kill BABY Dinos

4. Kill more (Baby) Dinos

5. Finish

Wear Flak,use shadowmanes for friendly meter and there ya go .
