People seem to overthink how to tame this guy so here's a simple guide:

1. Put on some ghillie.

2. Kill a baby rex or spino (wyverns and other similar tier dinos will probably work too, but I haven't tested them).

3. Drag it to the charchar.

4. Profit.

If you want to be fancy/safe, you can make a typical behemoth stone gate cage trap and lead it in. Yes it can break stone, but it won't be in the trap long enough to do so. Once you drag the dead baby in, open the gate and have fun on a rampage. Ghillie is there so the baby corpse doesn't accidentally get chomped while the carchar is trying to kill you.

No need for wasting metal on some overly complicated gate and bear trap setup.

No trap necessary! I’ve tamed 6 now and no trap is easier than dealing with the trap. Mate high level rexes, hatch eggs, and cryopod the babies. Find Carchar, kill ALL dinos in the immediate area. At a safe distance but in sight of carchar get high level baby rex(s) out of cryopod, kill them, drag to carchar and let them sniff and eat. Number of baby rex needed is dependent upon carchar level and your server taming rates. I recommend only killing one rex at a time otherwise carchar may end up going over to your pile and eating them and that will do you no good, trust me. If on extinction I recommend luring the carchar back into the snow biome if it has ended up out in the wasteland. The random spawning of corrupted can really add another level of difficulty to this tame.

In theory, you could use a mind wipe tonic, pump most your stats into weight and kill some adult rexes at the sight to use for feeding. I haven’t tried that though so experiment at your own risk.

On Extinction they spawn regularly on the outer edge of the snow biome from the southeast to southwest corner of the biome. I’ve found them on both sides, just inside or just outside of the biome.

They take forever to raise and imprint but they are well worth it if you can get some high level breeders. They are a giga on steroids with a better turning radius, a stamina boost, and a blood rage buff that drastically increases melee and heals them faster than they can take damage. I raised 6 that started around level 150 and got them mostly imprinted. Just riding one I am unstoppable, I can handle a purple supply drop up to wave 5 and not even be close to losing the carchar or dying myself. Unfortunately I lose the drop because there are more Dino’s spawning than one person and mount can handle.

Like all big Dino’s they don’t handle fall damage well so be careful there.

So friend and I tamed one this morning. Mated my rexes got 4 eggs to about 8% from hatching.(boosted hatch rates). Took the eggs close to where the carchar was, hatched one egg. Killed the rex and my buddy carried it up til it looked at him dropped the body and ran a little bit. Carchar ate the corpse and was ready to be mounted. No cage needed just got to have some massive balls.

Day 2: Charcharadontasauraus

Information:

The Charcharadontasauraus is one of the best Dino’s in the entire game with stats rivaling even the giga and has even more abilities and is an exceptional mount that can easily traverse the whole map and, with its amazing movement speed, very quickly. However, there is one major drawback: an extremely difficult tame and can eat right through any structure below metal. It has a wide range of different attacks including a basic front facing bite and I high power 360 tail spin that sends most creatures flying. It has one of the best abilities in the game, which is a stackable kill buff, and it stacks up to a hundred times, and with a full 100 buffs it can solo a wild giga.

Base stats:

Its health is absolutely incredible, ranking in at #3 next to only the titanasaur and the giga. Its melee is also astonishing with only 4 other creatures dealing more damage at 211 per hit on its base attack at level 1. The only major drawback to these amazing stats is that they get lowered an insane amount upon taming.

Taming:

The Carcharadontasaurus has an odd and unique way of taming that includes mounting it and killing other wild dinos, but before you can go off and kill other stuff, you need to trap it and feed it a dead dino. To trap it all you need is a flier, 4 metal dino gateways and a large bear trap. First, you will need to place down three of the four metal gateways in a U shape with one at the back and two on either side facing the same direction. You will then need to put the bear trap at the back of the trap, at the bottom of the U shape. Then, you will need to get on your flier and get the Charcha’s aggro and fly over the trap with it chasing you and lead it into the bear trap. You will then need to quickly run around to the back of the Charcha and place down the last gateway behind it, trapping it in the square of gates. The next thing you will need to do is, if possible, cryo a baby rex and bring it to your Charcha. You will need to throw out the baby Rex and kill it, then drag it to the Charcha and feed it to it. This will completely fill up its trust meter, allowing you to then destroy one of the gateways and mount the Charcha. If possible, try to get to a highly populated area with lots of dinos everywhere and kill everything you see. The bigger a dino is the more taming progress it will supply, but tons of small dinos can also be very effective. Once tamed, I would suggest putting four out of every five points into melee and the other one wherever you see best fit depending on you Charcha’s base stats, but that is just my recommendation, and if you want to do something else, feel free to.

Typically they spawn where ever gigas spawn. Once found one you have to kill some animals preferably a wholly Rhino. once you have the corpse it's a passive tame so makes it better to tame. Slowly walk up behind the Cardo wait till it sniffs the air and run away so it can it can be eaten. When the the hexagon is full above it hop on it as fast as you can and kill everything till it's tamed.

You can drag a body and feed it to the carcha with your tamed Dino and it will gain trust in the exact same way as if you’re dragging it yourself. Just walk up to a corpse on your Dino, place your dino’s mouth over the corpse, and press G. This works with most but not all tamed dinos. Your Dino will move very slow while dragging a body though.

I’ve tamed a couple of carchas by carrying wild mammoth/yutyrannus to some safe area near a carcha on a Rhynio, killing them, pressing G, and slowly flying up to the carcha. Saved the life of several rex babies.

Step 1:tame two rexes(Doesn't have to be high lv)

Step 2:Let them do funky time

Step 3:Pet the baby rex

Step 4:have the best time with him

Step 5:Cryo him

Step 6:Sacrifice him to mighty charchar

Step 7:kill hundreds of innocent creatures while riding the charchar

Step8:You have charchar

Step9:remember that gigas will always be da best

Step10:your done

Y'all don't actually need to trap it and prepare a baby Dino if U have a rhyniognatha, y'all just need to find a nearby rex or spino, carry it ALIVE to somewhere near the carcha but not near enough for it to notice U, kill the rex or spino U carried here and drag the body with ur rhyniognatha, it will be slow asf but trust the process. Once the carcha do a SNIFF animation just wait there for it to eat ur offering(btw if Ur wearing ghillie take it off just incase) and if it shows a green sign at top of it's head then congrats now just ride it and kill anything U see until it fully trust U(note that U might want a second flier or a parachute cuz rhynio won't follow U, maybe even a sleeping bag just incase ur didn't have time to react when it throws U off after tame)
