Ungulate Rex

This is either an alien pack animal or some future evolution creature. I was doodling fantasy creatures when I made this. I thought of it as a two legged ostrich-like mammal.

Its horn is mostly a trait of sexual dimorphism and to attract mates. Females and young have small dull horns, and as they mature may reach a length like the one featured in this picture. Male adults have much longer and deadlier horns.

They will rarely fight with their horns; if a horn manages to break off, they risk fatal brain injury. They lack a sense of smell and their hearing is weak, but they have astounding eyesight and sense vibrations though their feet.
