They’re located on the mountain closest to Carno Island. Make the trap either by the beach or at the base of the mountain so you don’t get attacked on the top or on your way up. Make a trap out of four stone dino gates and two doors. Use a pteranadon and lead it in, flying out when it goes in. I advise using tranq darts on a low level so you don’t kill it. Use Allosaurus Kibble on Ark Mobile. It would’ve taken me ages using it anyways, so be sure to get a Major Soothing Bomb from the store. It’s slightly expensive, but it saved me a hell of a lot of time in the long run. When you get them, level them up on stamina, health, and weight. Mellow damage is also a good idea.
Out of all the flyers they actually hit the hardest if you perfectly execute its dive swipe/slash, I killed two texes in one dive, its kind of hard to notice if you did it correctly but if it attacks with its left claw then its actually dive swiping, when it attacks with its right, its just a normal attack
I have to say they are pretty garbage when they are low level, cuz i could barely move without draining my stamina half way, but when these guys are high level, they outshine almost everything when it comes to combat, it hist like a truck when it has momentum and it's speed is unrivaled. Level these guys stamina first, you will really need it
