If you dont want to wait for their food and have an easy trap at the same time, do this: (usable at any lvl of the tame garanteed)

1. Bola and K.O. the pteranodon

2. Collect wood from surrounding trees

3. Put a wood pillar where the ptera is, then 5 thatch roofs ontop that looks like a cross

4. Put wooden railings under the roofs outlining the roofs

5. Trap is done, wake up ptera to test if he can escape (he shouldnt be able to, tested it even on inclined terrain)

6. Sleep nearby while he’s awake (brings his food to zero when you wake up)

7. Quickly K.O. Before his food is replenished, put kibble/meat

8. And done, to destroy the trap just remove the pillar (it should all go down if you destroy just the pillar)

Thx for reading, goodluck taming!
