I think (and I'm sure someone will jump in to correct me if I'm wrong) that marsupials are born out of a vagina when they are very tiny, and they have to crawl up to the pouch and get inside it where they then nurse for months and continue to develop. Then when they are finally big enough, they come out of the pouch.

So it would have had an umbilical cord (I guess) when it was in the uterus, but lost it when it was born.

Edit: Turns out I guessed wrong. It seems they don't have an umbilical cord in the uterus. They just live off of the yolk of an egg. Wtf?
