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.
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 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...
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.
