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 – Worlds in Shadow: Submerged Lands in Science, Memory and Myth

7-minute read

Long before we developed writing, humans communicated information across generations by telling stories. Professor of Oceanic Geoscience Patrick Nunn contends that some of these record actual environmental changes that impacted our ancestors. Scientists interested in the rather obscure discipline of geomythology argue that, when studied carefully, such oral histories can be an additional source of data to help us reconstruct past climates and understand their impact. Supremely absorbing, Worlds in Shadow covers a wider range of topics than Nunn’s previous books, making this of interest to a broader audience.

Book review – The Story of the Earth in 25 Rocks: Tales of Important Geological Puzzles and the People Who Solved Them

Judging by the title of this book, you might expect it to talk of 25 remarkable kinds of rocks and minerals. But in the preface, geologist and palaeontologist Donald R. Prothero makes clear that his book looks as much at famous outcrops and geological phenomena. Bringing together 25 readable and short chapters, he gives a wide-ranging tour through the history of geology, celebrating the many researchers who contributed to this discipline.
