Book review – The Greywacke: How a Priest, a Soldier and a Schoolteacher Uncovered 300 Million Years of History

7-minute read

Take a look at the geological time scale*. Thanks to the dinosaurs, we have all heard of the Cretaceous, Jurassic, and Triassic. However, going back in time from the Triassic, the Phanerozoic Eon in which we live today stretches another 289 million years into the past; from the Permian that ended ~252 million years ago, through the Carboniferous, Devonian, Silurian, Ordovician, to the Cambrian that started ~539 million years ago. In The Greywacke, amateur geologist Nick Davidson tells the story of how those geological periods got their names and transports the reader back to the heydays of Victorian geology when three men would make Britain’s rocks the centre of international attention. In so doing, he unlocks for a general audience an episode in the history of geology that was so far consigned to more technical literature.

Book review – Notes from Deep Time: A Journey Through Our Past and Future Worlds

6-minute read

Deep time is, to me, one of the most awe-inspiring concepts to come out of the earth sciences. Getting to grips with the incomprehensibly vast stretches of time over which geological processes play out is not easy. We are, in the words of geologist Marcia Bjornerud, naturally chronophobic. In Notes from Deep Time, author Helen Gordon presents a diverse and fascinating collection of essay-length chapters that give 16 different answers to the question: “What do we talk about when we talk about deep time?” This is one of those books whose title is very appropriate.

Book review – Essentials of Geology (13th Edition)

Like so many teenagers, I wanted to become a palaeontologist. However, there was no degree programme in palaeontology in the Netherlands back then (I doubt there is one nowadays), so I was advised that one option to prepare myself was to do a Master’s in biology or geology. I choose the former and never looked back, but remained fascinated with the latter. Now, twenty years later, my job exposes me to many geology textbooks and especially Cambridge University Press has a wonderful output of advanced-level books that I really want to read. But when I reviewed Earth History and Palaeogeography some time ago, I realised I was out of my depth and struggled with the jargon. Is it ever too late to start over and make an entry into a new field? I decided to shell out and invest in a textbook to find out.
