I used my Baryonyx to tame one of these guys (went to herbivore island to find one). There was SO many mantas but it was fine I used my bary to lead them to me then stun and kill them, it wasn’t hard at all. Taming was easy as well since I used the kibble. (On mobile btw), so just have a baryonyx by your side and go to herbivore island and you’ll be set.
