For starter if you want this thing the best way I got one is I killed one and took it revival thing went to the green crystal thing revive it Trang it with three Trang arrows and when it was knock use a smoothing pot and gave it 10 cooked meat and there you have it a new dino and best part it give you oxygen when you ride it or swim with it you don’t need a saddle just make sure it’s in the water
Can ride but only underwater. In order to ride, hold whatever your ride button is and click the option that says ride. Level up in oxygen, health, and movement speed if using this for underwater dives. Really fast underwater, and can outspeed megalodons.
Fantastic utility Dino. You take oxygen from it passively while riding. The oxygen lasts a long time too; this combined with its speed means you can explore anywhere under water. That and it's a chitin machine ;)
Diplocaulus are constantly picked on by swamp carnivores, even the sluggish Dilos, add on the fact that they are so painfully slow and it results in it constantly kicking the bucket.
For taming either take some strong tames to kill all swamp carnivores or, and this is worth noting, use a pteranodon/Tapejara to hook it out the swamp for easy pen taming
