Who am I?
I’m a science journalist in Colorado, living in the foothills of the Rocky Mountains that were raised by millions of years of mountain-building. I studied geology in college and now write about the earth and space sciences, primarily for the journal Nature. On reporting trips I’ve camped on floating Arctic sea ice and visited earthquake-ravaged mountains in Sichuan, China. But my favorite journey into deep time — the planet’s unfathomably long geologic history, as preserved in rocks — will always be a raft trip with scientists along a section of the Colorado River in Arizona.
Alexandra's book list on on deep time
Why did Alexandra love this book?
This gorgeously illustrated coffee-table volume draws on Black’s expertise in science writing and paleontology. She begins with the Big Bang that created the universe 13.8 billion years ago, then moves in short chapters through milestones of the rise of life on Earth. Prehistoric plants harden into coal in the Carboniferous Period, 359 million years ago; dinosaurs roam the Morrison Formation of the western US, 156 million years ago; and small blobs of molten glass from Laos reveal a powerful meteorite impact 790,000 years ago. You’ll never see the timeline of life the same way again.

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…
