Let's not forget, everyone, that the dossier says it can heal fast from eating, which is useful after fighting off NUMEROUS carnivores, like the giganotosaur. That means this thing is big and strong enough to take on several gigas. That's crazy amazing.
Also, due to its sheer size, does anyone else think that maybe rocks will spawn on its back? it would be really cool if we somehow managed to have a mobile mountain to harvest metal, flint, and rocks from. I mean, i doubt that's the case, but still, that would be pretty dope.
