TV scientist Ben Garrod presents the biggest extinction events ever, told from the point of view of the most incredible animals ever to swim, stalk, slither or walk our planet. Whether you're 9 or 90, his exploration of the most destructive, yet most creative, force in nature makes top-level science fun.

Hallucigenia was a super-weird, spiky, armoured worm that lived 450 million years ago. Scientists were, at first, unsure of which way round it went, and which way up. But here you will discover all Hallucigenia's secrets: where it lived, what it ate, why it was so weird and why it is so important in the story of life.
