Where did Australia's marsupials come from?

Starting point · 60 Ma

The image reconstructs the thylacine in recent historical times, not an ancestor from 55 million years ago.

Australian fossils around 55 million years old record early marsupials. Small clues such as Djarthia's teeth and ankle bones help reveal relationships. This is a fossil-record reference, not an exact first-arrival date.
