I feel like there is a minimum of these that can be in the wild, because I went out to tame a brontosaurus, and finally found one halfway across the map. So knocked it out, tamed it, and named it Big Al. Then, I finally got back to my base, saw a female Brontosaurus, and flipped out because it spawned right next to my base and was stepping on stuff. So my Dinosaurs killed it.
