I suggest that at the night try to find one and once you do wait till day but DONT GET IT AGGRO. Once it’s day grab it with a quetzal. Make sure you put it in a taming pen. Just saying it will be cranky try to shoot it with a tranquilizer dart. Depending on the level it will take longer. Give it the kibble and after a bit. You’ve got a lazy, strong dino XD. Just saying it won’t tame at night and it will wake.
Tame the mega during the day! It is extremly slower during the day due to wanting a rest. It is a very strong dino, it has been tested to be even stronger than the allo! Be careful if you tame it at night ;) caw
