I use y trap on the carno and it work up-vote so people will know

If you want the Lazy, Easy way of taming one of these, Get it to Agro onto a Diplo then use a Slingshot or Tranq Arrows/Bullets and You got yourself a easy carno tame.

I highly recommend getting up high on a boulder or getting the carno stuck somewhere while knocking it out. Unless you are a high level, you will not be able to outrun it.

Pretty good beginner dino, tamed a level 1 one just now-took 1 traq arrow from a cross bow to knock, 5 regular raw meat to tame, and I didn't even get hurt in the process. As well as doing a sufficient amount of damage to protect you, it has an ability to knock creatures back with its horns.

Probably your first canivore and it will make you feel like your the best of the best, or is that just me!?!?!
