Dr Richard Smith embarks on the final stage of his rollicking adventure through the geological history of Australia. From the formation of its landscape to the development of its wildlife in today's desert heart, we plunge into an ancient inland sea, full of monsters. But reptiles didn't have the world all to themselves. Mammals like the enigmatic platypus lived alongside them, ready for their moment in the sun.
