Slight sexual dimorphism: males have bigger ossicones, and the males fight for females. They use the ossicones for defense in the wild.
Scientists think they did not grow horns like rhinos since it would get in the way of reaching the leaves.
Ossicones on babies are pushed in to keep the mom and the baby safe during birth. This is much like the soft bones of a human baby.
