If you want to tame these creatures, i recommend you have a saddle for them, and have atleast tamed 2 creatures.

The stuff needed: 1 bola 1 bow 2 tranq arrows 20 meat and a saddle.

Taming:

Find a raptor and use the bola in it,

Start shooting the tranq arrows straight at the face, don't use any fists or clubs.

When unconscious, add the 20 raw meat into his inv, Wait

And boom! You now have. A ridable raptor
