I got level 95 very fast by killing Titanosaurs. The best way is to use a lightning Wyvern and fire it from above, watch your stamina. You can also use a very good Giga (good melee and good saddle is a must) to kill it fast, try to hide behind a Redwood tree, take your time and watch your stamina. If anything goes wrong (Giga stuck in a tree) dismount from it and shoot arrows at the Titan, it will start chasing you, hide behind a tree and wait. The titan will become passive. Good hunt and don't forget the broth for exp x2 ! :)
-It poops massive poops, the largest poops you’ll ever find.
-It’s a temporary tame since it can’t eat, so it dies from hunger.
-It’s the strongest Dino, and the best way to tame is putting cannons on quetzals and flying far enough it can’t reach you and you can still shoot it. Once it’s unconscious putting the saddle in its inventory will instantly tame it.
-On ark mobile, if you do the kill giga quest, you get a free titanosaur platform saddle.
-Although it’s tempting to build huge bases on it, since it’s a temporary tame it’s not worth it to try super big bases.
There is a setting called Enable Raid Dino Feeding, which let's you keep dinos that die from hunger because you aren't allowed to feed them normally. This allows you to keep your titanosuar forever! (If you feed it) I use it on single player.
Ok guys so all you need to tame it is a titanosaur platform saddle. It doesn’t eat anything and you don’t need any narcotics to tame it. Once you knock out the titan, place the saddle in it’s inventory and equip it to the titanosaur. Boom you just tamed a titanosaur! You’re welcome!
