I’ve never tamed this, but i have seen people do this. Make a quetzal platform then put it on a quetzal. Then, load storage boxes with cannonballs. Shoot the cannonballs at its head. Its really hard to aim, but its possible.
Titanosaur
The Titanosaur is the largest creature in Ark whose stats top the charts across the board. This sauropod's massive platform saddle allows tribes to build large fortresses on its back — if they're skilled enough to tame it.

I thought they were rare but I was playing on mobile and the first thing I see in a new world is 2 of them on the beach!!!
In ark mobile they spawn in masses on carno island
Mobile friends I found 3 on carno island which is not its spawn???
It doesn’t do 1000 damage it does 1800
Have two cannons on the back of a quetz and a storage holding the cannon balls with two guys shooting off the the back with one guy moving slowly forward
These guys eat on mobile I’m pretty sure , I don’t know about multiplayer though
My tribe tamed one of these for a raid thinking it would only last a day cause that's what all of us have heard. It's now been almost 4 days and is a little under half food. We're playing on official too
Box him in into battlement ( leave some space for movement), cannon him on head
(Sorry for my broken English)
They run away when you attack them with a pteranodon on mobile lol I’m being serious this isn’t a joke try it out
Should you ever use a canapolt:no reason be cause when it wiggles it neck then you miss then you end up killing it like I did
100 bloodrage carcha can decimate this beast with ease
On solo they do in fact eat and a good method to tame it is to bait it against a mountain with a quetzal for easy canon shots.
I found this guy and I had a question does this guy aggro
On you.
Wanna keep one forever in singleplayer? Here’s how! You know the set raid dino feeding setting? That allows the titanosaur to eat if you put it on. You might have to feed it yourself though still. And then the raid dino food drain multiplier, you can set it to 0.0 so the…
Wanna keep one forever in singleplayer? Here’s how! You know the set raid dino feeding setting? That allows the titanosaur to eat if you put it on. You might have to feed it yourself though still. And then the raid dino food drain multiplier, you can set it to 0.0 so the titanosaur doesn’t even loose a food point! Hopefully this was helpful as a mini guide to keep one alive.
You either kill the titan, tame it, or it destroys you and your creatures.
This guy can eat if you have the setting enabled (at least on console.)
Pretty sure I learned somewhere that the Titanosaur doesn’t eat on purpose because it would rather die than be enslaved. It doesn’t have a brain disorder guys calm down.
THEY WILL EAT ON ARK MOBILE IF YOU ARE RIDING IT
Bleep bloop blom goodbye to my thatch base r.i.p
