When i went ou for search of mosa for first time i found a alpha mosa that the the first miss i saw . I fried to kill it but it got despawned .Till now i have seen all alpha creatures.the first alpha was alpha rex .

Dont put a lot of tranquilizers in its inventory when taming because it will eat everything there when tamed and the constant rising torpor get annoying

Tame some use less creatures and feed to mosa and stay relaxed and feel free to knock it out

WARNING KEEP ALL CREATURE S IN PASSIVE AND ALSO HAVE A GET A WAY RIDE IF IT AGRO ON YOU OR TRYS TO KILL YOU AFTER KILLING ALL OTHERS

I PREFER BASILO FOR THE USELESS PART CAUSE THEY HAVE MORE HEALTH AND ITS PASSIVE TAME if you want any creature is ok

My squid named kraken is a knockoff kraken I tried to pick one up but failed, and then killed it for not cooperating

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

Stumbling across a 23 alpha mosa without ever seeing one

Rip

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!

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

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 🫠

If you manage to tame this big dude and craft him a saddle just ride him and terrorize everything in sight

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

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!

Mosas are powerful and can have platform saddles so you can put a catapult on with jar of pitch to make a fiery end to your foes

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.
