When Tim Flannery was a boy, he found a fossilised tooth of the giant shark megalodon at a beach near his home. This remarkable find sparked an interest in palaeontology and a lifelong quest to uncover the secrets of the world's largest ever predator. Tim passed on his love of the natural world and interest in the fossil record to his daughter, Emma. And now, together, they have written a fascinating account of this ancient marine creature. Big Meg charts the evolution of the megalodon, its super-predator status for about 15 million years and its decline and extinction. It delves into the fossil record to answer questions about its behaviour and role in shaping marine ecosystems as well as its impact on the human psyche. It contains stories of the scientists and amateur fossil hunters who have scoured the seas, and land, for fossil remains, drawn to the beauty and mystique of the great shark – some meeting their end in the quest, Like the fossil record itself, this enthralling story is a piece of the great natural history of our planet.
