Megalania

Sean is in Australia, tracking down a legendary beast-- the Megalania. The Megalania is a gigantic ancient reptile that is rumored to still live in the remote microclimates of Australia's Greater Blue Mountains. Although most academics agree a massive drought 30,000 years ago spawned a water shortage wiping out these giant reptiles, theories exist that a few could have survived. Sean travels through the arid grasslands, slot canyons, and dense rainforests of New South Wales in search of the giant predatory reptile.
