What is the life cycle of a diprotodon?

The Diprotodon's life cycle can only be guessed at, as it disappeared long before humans made any studies or observations of ancient fauna.

The male was believed to be larger than the female, and also believed to mate with any number of females. The Diprotodon reared its young in a pouch, where the young fed from a teat in much e same way as today's wombats do. There are several cases where the skeleton of a female Diprotodon has been found with a baby still in its mother's pouch.
