The story of life on Earth through the planet's major mass extinctions. Book one, Hallucigenia, is about a weird worm that lived 443 million years ago. TV scientist Professor Ben Garrod presents a unique exploration of the most iconic animals ever to walk, swim, waddle or stalk our planet. A collectable, full-colour eight-book series, illustrated by foremost paleo-artist Gabriel Ugueto.

For as long as there have been species, there has been extinction. What causes it? Why do some species go extinct and what can we do to save endangered species? As many as 99% of species that have ever lived have gone extinct, which means we have already lost an almost unbelievable 5 billion species from our planet. In his new series, Ben Garrod explores how extinction is one of the most complex, interesting and constantly evolving topics to study right now in science.

Each book will focus on the landscape of one extinction and one animal lost. Hallucigenia was a tiny, weird, spiky, armoured worm that lived during the Ordovician period 443 million years ago. How do we know about its evolution, anatomy, behaviour, habitat and food chain? How do we know what led to its extinction? With an additional 'Ask the Expert' section, stunning full-colour art on every page, glossary and pronunciation guide, each book will reveal a different extinction story, from mass extinctions caused by asteroids or mega volcanoes, to over-hunting by humans and habitat destruction.
