Nova: Australia's First 4 Billion Years (Blu-ray)

Of all continents on Earth, none preserves a more spectacular story of its origins than Australia. With help from high-energy host and geologist Richard Smith, we meet titanic dinosaurs and giant kangaroos, sea monsters and prehistoric crustaceans, disappearing mountains and deadly asteroids. Epic in scope, intimate in nature, this is the untold story of the Land Down Under, the one island continent that has got it all.
