Compared with the dinosaurs, wiped out 66 million years ago, this is but a stone's throw into our planet's shadowy past when monsters reigned.

Yet the Megalodon has been largely absent from the fossil record, leaving behind only a smattering of teeth and vertebrae prized by collectors, its existence steeped in mystery... until now. Marking a milestone in palaeontology, Tim Flannery, celebrated environmentalist, zoologist and explorer, and his scientist daughter Emma, tell the story of the giant shark for the first time.

Big Meg follows the quest to demystify the colossus that left Earth with barely a trace, reveals where and how it lived, and discusses the theories and haunting stories surrounding this ancient legendary creature, including that it may still stalk the deep... This is the biography of the ultimate apex predator - a vital piece of the great natural history of our planet - and a compelling exploration of its awesome grip on the human imagination today.
