You're a genius! I had been thinking of using prehistoric models to guide my flora decisions, but the Phanerozoic and Greenland articles have started lovely new trails of thought!

As to the tropical rainforests, in the short time I have lived in Sydney, ginger has become vastly easier to grow here, so I'll not rule out the option yet ;-) Is it wrong to hope for giant birds?

Thank you very very much for your well considered and beautifully linked comment!
