How to tame:

1: Get a bunch of bolas or bear traps if u have access to it.

2: Find the raptor and immobilize it.

3: Knock it out (I recommend using tranq darts, tranq arrows and a crossbow)

4: Feed it prime meat or their preferred kibble.

5: Make sure to feed it some narcotics if their torpor is really low.

6: Equip the saddle!

7: Tame 5 of these and you'll be safe when exploring.
