When I spawned in South zone 3 I found this guy stuck on a rock next to the surface. I went and killed some dodos and that my friends is how I tamed a basilosaur before a dodo.

Even if you don’t have the saddle Engram for it you can use it as a way to get free oil 😱😱😱😱. Like so low level ppl can see

Good fighter, immune to jellies, supernatural healing boost at the surface, produces oil in its inventory, impervious to squid grabs, looks kinda cute too, only one bad thing about it: it gets squashed in the deep! Only slowly but the damage is there!

A living oil mine and immune to jellyfish and someone who likes to ignore the hug of the Tuso . Yup definitely worth taming and for some of you who don’t know how to tame this kind of Dino then this is how you do it
Step 1: put the item you will use to tame in your hot bar
Step 2: get close to the Dino then tap the item to feed it then keep feeding it until it tame up
I am telling process because I had problems passive taming when I was a beginner
Hope this was helpful :)

This creature is so easy to tame. All you need is:
1. An Ichthyosaurus(these guy won't be attack by any water creature, except the jellyfish)
2. Anykind of meat(I suggest using prime meat and don't use fish meat)
3. Find one of these creature
4. Feed it prime meat(It's a long time between the 1st and the 2nd feed, after the 2nd feed it's fast)
And then you get one of these, just be careful of the megalodons, they will attack right after it is tamed. I hope this is useful for you<3

I would take a barryonyx to tame basilosaurus mainly because of the rays.

Oh my god it does not get effected my jellyfish this is one of the best creatures ever.

Good for farming bio toxin, as it can attack Cnidaria without being stunned or knocking off the rider. Takes damage when it goes too deep, though surfacing rapidly heals it.

Mine just ate an alpha mosasaur.

Watch out for its manta cult.

For the people who are having a really hard time taming this creature and it’s tame bar resetting when that happens I recommend using some prime meat and kibble anything that can make the taming percentage high I used a smoothing balm 10x in ark mobile got a 10x taming boost I just fed the basilosaures 1thrizinosaures egg kibble and it was tamed

Two things I found to make these incredibly easy to tame:

1. Baryonyx - this guy will destroy the mantas and anything else that will threaten your taming

2. Scuba gear for ease of life underwater for the next 10 mins

Job done!

In real life these were vicious carnivores that would have killed and eaten a human on sight and lived mostly in shallow waters and swam up rivers looking for food they were also twenty metres long, good thing the developers didn't make them more realistic or crossing rivers would be a dream until you have a flyer.

Up if it would be cool to have a mini platform

Build a raft attach a ballista to the front and re-live the epic tale of moby dick, a-hoy mateys

Fun fact: the first time you feed it, it takes a while. The rest of the time, it’s much faster, don’t worry!

Can kill squid like their kin in real life. Tame a 150 and you can take on alphas like they are regular ones. Just up health and memes. They recover steam so quick boosting it is pointless. An all around amazing creature, 10/10.

Basilos, one of, if not, the best aquatic mount in the game. Not able to be stung by the jellyfish, healing quickly at the surface, and for being a whale for ARK's sake. They have tons of weight, damage, and, best of all, the potential for a MASSIVE health pool. I bred a fully imprinted, non-mutated Basilo for the first time today, and after killing an alpha Meg and Leedsichthys, it has nearly 200,000 health. Damage-wise, it isn't too crazy, but it is especially good for an aquatic mount. The only aquatic creatures to rival the Basilo in its capabilities are the Most and Tuso, and possibly the Plesio as well. The Miss was the original King of the Sea, but ever since Jellyfish were added, they have been in a fire need for a TLC. The Plesio is fast, but it doesn't do as much damage and is not as manuverable as the Basilo. That leaves the Tuso. It has a long reach, but Basilos are not affected by its grip. This truly proves they are the King of the Ocean.

I don’t know what everyone else did but In my experience the Icythaurus or whatever the dolphin is called, still gets attacked. Everything is chasing me on it. Sure I can out run everything but the tips here made it sound like you would get ignored.

Also, someone said you could tame it from the saddle you can’t you have to dismount.

Now this is all PS4.

So best bet is to have 2 - 3 people 1 to feed and the others to agro and lure away the mantas and megs.

Icys are fastest in my experience. So best bet to bait away and dart in and out.
