Always spawn on the Island near Green Ob, and near to Red Ob. Use bola, and full gillie suit to approach. Make sure you are crouching when you approach one. I've had Taps on official and unofficial. Great multi purpose tame for tribes. Not so good for solo players unless you get the tek engram for the saddle
Story Time (I don’t know if this is the right category but watch ever)
Tapejaras are hard to find, hard to tame and hard to protect while taming, I discovered that in the hard way.
During my entire time playing Ark(mobile) I only seen 3 Tapejaras , I tried taming all of them.
The first one escaped because I ran out of food and narcotics.
The second one I tamed, and then he got killed by a Spino seconds later.
Due to luck and previous experience I managed to tame the third one , I named him Jack, and he still alive and I hope it keep on going like that .
Sooo, I hope this was useful, or at least entertaining, so what are you waiting? Go tame one! They really nice if they survive the tame they can survive almost everything I guess
