I tamed one of these guys on craggs island, they are quite good tames even without a saddle because they take on just about everything and their horns are natural sunglasses so they can fight in the summer!
Me: let’s go get some fish!
Me: sees spino.
Me: oh no! Goes the other way.
Caro: zooms in from nowhere.
Carno: is speed.
Diplodocus: AAAAAAAAAAAAAAAAAAAAA CARNO FIGHT ME INSTEAD
me: thank you massive dino.
I encountered one of these on my first day of ark, it was my fault I died from it because I went to the swamp when I was only on level two. At first a though it was an allosaurus, but I soon found out that it was a Carno. I’ve decided that I’m staying out of the swamp until I’m a higher level and when I have a couple dilos.
