Carving a timeline through the aeons of evolution that have taken place before our time on Earth, Deep Time explores the evidence that exists beneath our feet, in our museums, in the skies and surrounding us every day, which can help us to make sense of the great age of our world.

Deep time is the timescale of the geological events that have shaped our planet. Whilst so immense as to challenge human understanding, its evidence is nonetheless visible all around us.

Through explanations of the latest research and over 200 fascinating images, Deep Time explores this evidence, from the visible layers in ancient rock to the hiss of static on the radio, and from fossilized shark's teeth to underwater forests. These relics of ancient epochs, many of which we can see and touch today, connect our present to the distant past and answer broader questions about our place in the timeline of the Earth.

Charting 4.5 billion years of geological history, this is the story of our world, from its birth to the dawn of civilization.
