Diprotodons are very large early relatives of modern wombats. Marsupial herbivores, they are heavily-built quadrupeds about man-height at the shoulders and twice that in length. Diprotodons prefer dry plains, savannahs, or open woodlands. They are usually encountered in small family groups of one male, several females, and young.
