wombat's back is...

The wombat's back is rounded and slopes downward. It is also hard and bony. It's covered with very thick, tough skin which is hard as a board and protects the wombat from injury or attack. This bony back is a useful defence against intruders in the burrow, as the wombat uses its back to crush them against the burrow wall.
