Quick tip for new/replaying people, TAME A CARBONEMYS. They are super easy to find, very easy to get food for, easy to tranq, only kinda hard thing is getting a saddle for them. But if you get past that bit, you get a early game tank that can solo raptor packs. Now for the tip on the carnotauurus, get two carbonemys,(or one high hp one) and shoot tranq arrows at it while mounted on one. Put one of them on neutral, and let it attack the carno to distract it, and just shoot it over and over. Don’t get off the mount though, or else you die. If you got only one, you might just be fine shooting it while mounted if it’s got 3500+hp
So back when i was a new ark player i tamed 8 raptors just for defense, later on i spotted an alpha carno walking down the beach towards my base, and not wanting my newly tamed sarco, and trike to die, I did something any normal person with 8 raptors would do. Me and the pack and charged into battle, lets just say i lost all but one, Silver. Shes still alive today and happy, And we did kill the alpha carno.
