Monotremes Diverged from Marsupials Earlier than Thought

An interesting piece of news from the ABC if you’re into Australia’s wierd wildlife, apparently marsupials (kangaroos, wallabies, koalas, etc) and monotremes (egg laying mammals, the platypus and the echidna) diverged much earlier than previously thought. This is based on a fossil of a 115-million-year-old relative of the platypus found in Victoria.
