(On the island) There is a pretty easy way to kill titanos (easiest in the outskirts of the redwoods) with just any one giga or carchar (recommended to be 90+ blood rage if youre using carchar)

First things first, you need to aggro it, you can shoot it with a ranged weapon or by hitting it with your dino (most safe to walk behind it and hit its tail) if youre riding a giga, bite the tail first, while it turns around to face you, turn your giga around and wait for the titanos head to be in your face pretty much, from here you just need to walk forwards while biting the head (really easy with the gigas huge aoe) and if it tries to run from you, either chase it while biting its tail or stop and regen stamina, and repeat the previous steps until its dead

If youre riding a carchar, first kill other wild creatures around the area to rack up blood rage and then aggro the titano

Killing it with the carchar is as easy as walking backwards and biting its face until it dies, and when it starts running away like with the giga either chase it and bite the tail or stop for stamina

And thats my preferred method of killing titanosaurs whether it be for xp, hide, or just for fun

I was always curious about Titanosaurs damage, and if it was stronger than a giga. So one day, I came across one with my high-level PT. So, instead of looking on DODODEX or the WIKI, I decided to hit it, fly UNDER ITS FEET, AND WAIT FOR IT TO SMASH ME FLAT. In the few milliseconds before it’s feet came down, I realized how stupid this was. Stormfly was killed in one hit, I was blasted across the map into a pack of raptors. I managed to revive my PT later, luckily. But the real lesson in this story is DO NOT MAKE THEM MAD OR YOU AND ALL YOUR TAMES WILL DIE.

Im on mobile so i do not know if it will work on other platform too

-Easy exp if you ask me, i'm lv 79 and had killed 2 so far, they give hell lot of prime meats and give about 5000 exps

-Simply lure it into the ocean,deep enough to cover it entire body,next mount a dino that deal ton of damage because this boi is amored,lastly swim above it body and attack all you want as long as you above it body it wont be able to hit you

-Make sure your dino have good amor and health to suvive a couple of hit from the titan since sometime the titan will try to go back on shore, if this happened you could either use you dino and attack the titan then go back to the ocean and contineus the beating or use a bow or crossbow to shot it (gun wont work since you are IN THE WATER)and contineus the beating

-When it at about 70000 health left lure the titan up so it can get some air then lead it back to the ocean and contineus the beating until it died, when it at low health it will run from you(YES it will run from you)which it will more likely swim farther into the ocean and get itself downed before you could even kill it

-killing the titan this way is time-consuming(took me about 30 minutes)but its the cheapest way i found so enjoy

-Some of you reading this may think im crazy or stupid or

im just lying but trust me, try it for yourself, just in case if you messed up remember to back up your save file
