Found one on herbivore island (I think that is what is was)
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.

Player-written tips for taming, using, and fighting the Titanosaur in ARK: Survival Ascended & Evolved.
I figured out that in a simgle player server you can force feed them berries so they domt starve
If your lazy use cheat ForceTame or ifbtour in singl player use ForceTame then while on it use cheat infinite stats then boom a forever titano
It’s not hard me and my pal did it in like 45 mins tops
4 m.s.c.m why? just think about all the people who could tame this really easyly useing a mek I mean it takes a lot of resources but it takes absolutely no skill to knock it out with the m.s.c.m..
I saw two of them at the same time at the same place, 1 level 1 male and 1 level 1 female at the border of the snow biome.

Honestly the best way to get one is to use M.S.C.M but if your on mobile use quetzal fly in the air and hit his/her head with cannon balls. If your aim is coo coo doo doo than use rocket launcher and hit him in the face.
Here is someone helpful:
These guys die in 24 real hours after you tame them no point in feeding it because, well, there is no food for it because they are extremely OP.

Pls DO NOT bite it with a beelzebufo. I did and in half a second it turned around and stepped on us mid jump.
Try I dare you 🙄 Base 💀 dead
On mobile, if you are an unofficial server admin and you tame a titan, ‘heal all’ on admin console will fix it’s food stat. My tribemate and I tamed a titan a month ago on my server and we still have it due to daily ‘heal all’s.
I saw one at level like 2 or 5 and was like woooooow thats a good worthy thing now im on griffins and quetzals trying to knock 1 it sucks btdubs tame one with grapples its a living swing of death
We could just let it wander and feed itself. Turn off friendly fire in settings so it doesn't hurt other tamed dinos
Titanosaurs are so huge that they are basically faster than some other dinos in the wild. This does not apply when you tame them...
The tape idea didn’t work, 60 element later and it died 😭
You can use the lightning wyvern because the lightning wyvern will take to par damage
If you attached by something run under the titanosaur it will help you if you dont get hit
I spent 30 mins trying to knock it out with tranq arrows and a bow then I was like fck it I ran up to it then saw 2.300,000 health
