This creatures are not much rare but to tame them is really very hard, because if they see you they ran away so fast that you can't catch and if you caught them some how there will some carnivore creatures they will kill your tapejara very easily and you will only get is a meat of tapejara that's it.... If you really want to tame them you have find their spot if they are on the land. And call out your strongest creature who can kill almost all dinos by himself so that your tapejara is safe. And you can finally tame them. But pls soothing balm before feeding them food, because it takes a lot of time to tame them. And pls take atleast 5 spikewalls with you to keep them safe while feeding them food.
