The best tame to get on single-player. Here's why:

- They can carry a lot of creatures so it's easy to put them in a trap to tame them.

- They are very powerful: with some points into hp and a lot of points into melee damage they can easily kill alphas.

- They have a lot of weight and weight reduction on some resources so you can carry your ankylo/doedic up to a mountain and easily harvest and carry hundreds of stone and metal back to base.

- They aren't the fastest mount but they do have a lot of stamina so they're pretty good scouts.
