If only we had some decent K/T deposits in southern Australia. It would have
been well away from the impact site in the Yucatan, and the dinos there were
showing adaptations to cold dark conditions at least since the Early Cretaceous.
If I had to bet on the last place in the world that dinosaurs managed to
survive, Australia would be it. Faunally speaking it's always been a weird place
(take the platypus as exibit A).
