Found a level 116 on the corner of the snow biome. Dissapeared after a plesiosnack

Get a basilo with at least 20 k health, kill all danger around you and mosa. After that let the mosa attack your passive basilo and swim above the invisible line where it can’t cross and shoot it with your crossbow. Hard part is chasing it when it’s almost knocked out

I went looking for one, instead I found a alpha mosasaur, a liopluerodon, and a plesiosaur. I gave up on the mosasaur and settled for the plesiosaur. You find them at the bottom of the ocean, as well as the alpha, which is almost invincible, may I tell you, and the plesiosaur, which looks like the clown from your nightmares and is just as aggressive, just getting down there takes 15 megs, quite a few annoying ichthys, maybe a manta, oh, and the liopluerodon, and no, it’s not a ‘yay’, ‘cause they only stay tamed for half an hour. The electro dudes don’t help the strive, and neither do the anglers. The baso isn’t much of a problem, it’s body guards are. And it’s not even likely you’ll find one, nor have the oxygen to tame it. The levels for the saddles are obnoxious, isn’t it already a hard tame? Just saying, though they are pretty strong, they are VERY, VERY, VERY, hard to get.

- Yours truly, the annoyed ARK person.

So you want to tame a mosa??? You came to the right place! What you must have

Mastercraft plesiosaur saddle

Plesiosaur

Toxicants arrow

Crossbows

Pro tip compound bow

Plesiosaur saddle free for doing no air pursuit!! Freee

next go around the map a couple times do a tidy save if you can't find one before you explore the plesiosaur cannot be knocked out from jelly fish and dumb eels

Last time I found level 6 moss to bad my toxicants arrows were out :(

... time to do it again

Tip for easy taming

1 there are 2 ways to tame find one then let it fallow you to the surface until it unaggros you then shoot with traqs

1 and a half, use a tuso to grab the mosa witch will do torpor then have a tribe mate also shoot it with traqs

2find a mosa I found a lot on hard mode from Carino island to green ob

3 when it’s unconscious feed it quets kibble but I used raw prime meat worked fine just took longer

4 rule the ocean

5 up if this helped

I found my mosa near a Florida- looking edge on edge of the middle right of the map. I brought a Ramshackle Crossbow and 150 Tranquizer Arrows (jelly arrows) and took it out with only 49. Used a soothing balm (X10) and fed it fish meat cuz my Ichy ate all my good food. It woke up at 47%, so I headed back to base to try again. This time, I used my same tool, and the Mosa still had the soothing balm on it so I was like 'yay'. I tranq it out again with 307 Bio Toxins and fed it prime fish meat (27% per bite) and it worked! Mine looks like a legit killer goldfish. I hope this helps!

Stumbling across a 23 alpha mosa without ever seeing one

Rip

Easy tame on genesis 2. Build 2 behemoth gates and block off a small section in the Crossway between the middle and NE quadrant. Leuer them in, shut the gate behind them. May need a good shark or something to fight off any thing else that follows you in. Should work for plesio and tusso too

i was vibing at the bottom of the ocean looking for a dunkle to tame and i got a bit annoyed since i was searching for 50 minutes i think and i decide to quit. when i look up i see a high level alpha mosasaur that literally spawned on me. i no longer have a megalodon (im on mobile) f for gallimimus the megaldon

Lol these are hard tames solo trust me

I found one in craggs island in the depths

There’s the basilosaurus and this scary bus-turd

And the way to tell the difference between which one eats you is that the one that eats you doesn’t have a swarm of fish behind it that will eat you 🫠

Number one Best at gathering raw prime fish meat

Bring an Itchyosaurus with you since they're pretty fast and things won't aggro it (at least on Mobile idk about PC/Console). Have a LOT of tranq/toxicant arrows, and search for your Mosa. When you find one, shoot it and let it follow you up to the surface.

Mosasaurs have a certain depth they need to be so they'll stop aggro when you reach a certain depth (near surface) and go ham with your special sleepy time ammo.

Make sure to watch its HP and Torpor so ALWAYS BRING A TELESCOPE WHEN TAMING ANYTHING! Don't kill the poor guy.

Give it some soothing balm if you can and feed it some prime fish and so on, use BIO Toxin to keep it asleep (you can get some from Cnardias probably nearby). Boom! You've got the Giga of the sea.. Sorta.

Hope this helps and good luck!

This tame is a long process amd can take a while to fond the one your looking for .

Get a tuso and grab him and drag him to surface. He will try to run because your so high up but that fine just re grab him. Then get him beached, in a trap or stuck in some rocks and there you go.

Easy tame if you use a Behemoth Gate trap, place four gates down and one door on each end, leave enough space you can swim through with an Ichthy, have one door on the gates at either end, leave one closed, get it’s aggro on lure it in, swim around behind it & shut the door. Tranq and kibble. Easy Mosa.

Use the mosa with a tek saddle for ta king turrets at under water bases

in ark mobile just kill it and grab it's implant make a revival platform put revival platform in the water under the red oblisk revive it there you go it will not move since it has a depth limit sometimes it might try to swim away from you and it stops since it has a depth limit it's easier to tame and much more expensive to revive lol

Tamed a 135 with a wood trap, a crossbow and a diplocaulus day 2, no where near as hard of a tame as it seems. No scuba no harpoon no stone, took maybe 2 hours and only that much because jellyfish killed me
