On a 135, 13 crossbow shots DO have a chance of killing it. Like so Dododex can see.

I used long rifle and darts worked. The eggs look like eyeball

They are skittish but not anywhere near faster than humans. They have low torpor and health, so tranq darts are recommended. Tamed like any carnivore, kibble is Archeopteryx. Can be found anywhere in and around the swamps.

Useful to supply oxygen to divers who do not have scuba gear at hand but very weak in battle.

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

They eat kibble differently from other dino.. normal dinos like rex or quetzal eat 1 kibble every 80 food but the diplocalus eats 1 kibble every 120 food.. you need to re-adjust and calculate it again

This creature is one of the few in which the other swamp dwellers have no allegiance to. I would recommend you to take and argentavis and fly the creature out of the swamp and tame it somewhere safer.

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 ;)

Use this to kill trilobites.. it kills and collects in 1 hit collects pearls chitin and oil that way.. quite alot!

If your in ragnarok just go to the desert ponds or lakes and hover over with a griffin straight down and shoot it with your rifle

Put it in water with you bring up its command wheel to ride. While your riding it it will share oxygen.

Very difficult to tame in PVE since you can’t pick it up and it’s every gator’s favorite snack. 9/10 Times you will find them getting eaten. I recommend taking a taming raft to the edges of the swamp near the ocean and using rare flowers to aggro it into your boat. Have a buddy scout with a flyer to find one. They have low health so be careful not to kill it. You might want to force feed to get the health back up after KO’d.

Use spyglass to find diplocaulus
The oxygen info is white and stands out against normal yellow green and red and is larger font...
There are very week Dino so kill everything that breaths on it, around it

Since they are often being killed by the other local fauna in their habitat, but can be picked up by a pteranodon, my strategy is to patrol until you find one, pick it up and carry it to a safe taming area. Just keep Kaprosuchus in mind while following tthis idea since they can grab you off of your bird...

For pve servers: you can pull these with grappling hooks but if the spook they will come free, hook them real it WAY out then you can jump on a flyer to cart it home - just fly high enough you don’t drag it into something bad.

These can be a pain to spot cause of the overgrowth in the swamps etc. Just look for other dinos chasing something, I don't think iv ever found one that wasn't being chased by something else.

These are bola-able so u can tranq them and tame

The karpo can carry them with his secondary attack very useful for capturing them in the swamp

These things can be weak so don’t shoot them too much with tranqs otherwise they could die.

This thing is a floppy cute weird aquatic animal, found near water. Quite hard to find from my experience.

These guys are a primitive scuba gear. If you play on primitive these guys are a necessity for deep sea crates.
