Fish, SO SO much fish.

If your In genesis 1 and you are fighting a x mosa bring about 2000 shocking tranq darts

(Tip they spawn at the ocean)

Get one guy to hold it with squid. Move it closer to surface and have other guy tranq arrow it.

Attack an Ammonite witch will give you a rage effect then bring the Mosasaurus to the surface and it will stay there then knock it out idk if it works on of but it works on mobile

Try to grab it with a tuso and then have a tribe mate shooting it with tranqs so that it is knocked out faster and can’t damage you or your tribe mate.

Make sure when taming this or any non passive ocean tame, to use tranq spears and harpoon lajnchers to split your knockout time in half.

This is an easy tame, just get an itchy and shoot tranq darts at it while a couple body lengths above its head, mine dissapeared due to a glitch though (in mobile)

Alright so I was looking for a mosa and couldn’t find one for a while as if they went extinct but then something came form the back… an ALPHA MOSA. I wasn’t prepared for this but luckily the tame I had was very fast so we swam away quickly still low health. (I got a mosa btw :D)

If you find one just hide and hope it does not find you.

Does not attack you in really shallow water

Tip for knocking out grab with tuso then have your friend shoot it with traqs

I find it easiest to build a trap using 4-5 behomoth gateways (arranged parallel to eachother in a “rib cage” like formation with 2 gates on either end, leave a little space between just enough to slip through with an Icthy or Megalodon) in order to tame a Mosa, simply leave one side open to lure the Mosa through before speeding behind it and shutting it in.

Bring lots of bolts and/or arrows and a healthy amount of narcotics because its topor depletes fast.

It's not too hard to tame one of these if you have a deep sea taming pen/raft (it's possible! I'm surprised too). Just be wary of that bite it packs a punch. Lured it in the cage with some barys bred for speed and had a tribemate seal it in. Be prepared to wait a while and bring plenty of quetzal kibble or mutton if you can.

Tranq this creature from above their depth limit. They will run away as their topor increases so bring a Megaladon or a Mosa if you somehow managed to get one.

Easiest method to KO - Grab the mosa with a tuso and bring toto shallow waters. There you can get a tribe mate to KO it, or if you're solo like me, you can drop the mosa and if the water is shallow enough it will stay still and it's an easy KO

Hi didn’t know where else to put this but everyone always does looking for pearls underwater just go to herbivore island on the island map it has dozens on the beach I got 1075 in like 5 minutes

I tamed my Mosasaurus with a Sarcosuchus. The Sarco was very fast and was able to instantly regenerate stamina underwater. I was able to shoot tranquilizer arrows from the Sarco’s back. I also used a SCUBA tank so I didn’t have to surface in order to breathe. The Mosasaurus was level 6 when it was wild. I was on mobile, so I took a soothing balm, gave it to the Mosasaurus, gave it some meat, and used about 100 narcotics. With the soothing balm, it only took about 11 meat to tame. He now sits in the water right by my raft and has to defend himself from sharks every once in a while.

Grab with a tuso while a tribe mate tranqs it for an easy tame

The x-mosa crossbow tranq amount is way out. On official i had to use an extra 100 tranqs for a lvl 90. Bring alot of extra arrows.

If you can’t find one, just go to their spawn locations and kill everything there until one spawns. Hopefully this helps :)
