You find these just about everywhere. Mostly in the tundra in small 2-3 packs. However, you may also find packs of them in the redwood mountains or large grass plains, and of course on carnivore island.
For those who read my rex story (about a rex on the other island and swam back a couple of seconds later and I was killed by a scorpion) This devil killed me the second when I reopened (near forest) I thought they were only in tundra or snow, I guess not :(
I just about had my Griffin Tamed, then this guy came over Lvl 177 killed me and my Griffin. Rip in the chat. Next time if you see one run away or bola in tame it kill it or run away. Very fast. 130 movement speed at least. Likes for the Griffin!!!😭😭😭
