I would use and argy to carry back to base and tamr in a pen. Start with darts because of low health then prime feed them. Get a higher lvl because oxygen lvl are much higher and then you can put the points into health and damage
All these tips here tells you how to tame it... but what they fail to mention is the fact, you have to breed it on land, can’t move the egg and the baby HAVE to STAY IN THE WATER!! Don’t push the baby on land or it WILL EXPLODE!!!! I just watch my baby explode right before my eyes!!! Never have I seen a Dino exposed before!!!
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.
