Sabertooth is best for chitin

Its easy to tame even

Don't make traps just sit on your Argentines

Who has good health and make his behaviour passive( to make it passive go in visstle option and do passive) then just knock him down using tranq arrows it would be useful

Tame it is meaning the fastest way is if you bola it and have a Woden club and go behind it knock it out

Create a small stone trap where you can catch it, mainly with 4 stone Foundations, and 16 Stone Doorframes.

You can bola sabertooth so will be easy to tame and tranq it
