Fun to tame and hard to kill,.can recruit alpha carno. Best way to kill is with allosaurs, the bleed can separate it from the carnos. This is very useful for taming, as long as you don't find another, they kill each other when wild.
Maximum size of creatures it can fear roar is rexes, which are just as hard to tame
First day it was released, started a new character made a stone house boat and headed north. Was docked, taming a direwolf. Suddenly it drops from a cliff with 3 carnos. They surrounded my boat and wiped me in three minutes. If you see the buff, gtfo.
