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.
Shelter. Yield. Dispose.
These three tasks, so says nature writer Robert Macfarlane, signify our relationship with the world beneath our feet, both across time and across cultures. Underland is his lyrical exploration of underground spaces where people have sought shelter from warfare or hidden valuable treasures, are extracting minerals in mines or knowledge in research facilities, or are looking to dispose of waste. It is one of two big books published only five months apart on the subterranean realm, the other being Will Hunt’s Underground: A Human History of the Worlds Beneath Our Feet which I will be reviewing next. But first, Underland.
Not so long ago, the idea that giant reptiles once roamed the earth was novel, unbelievable to some, but their reign represents only one part of deep time. Go back further in time, to the Carboniferous (358.9 to 298.9 million years ago), and you will find a world of giants as bizarre and otherworldly as the dinosaurs must have once seemed to us. A world where clubmoss trees grew up to 50 metres tall, with scorpions as large as dogs and flying insects the size of seagulls. With Carboniferous Giants and Mass Extinction, palaeobiologist George McGhee, Jr. presents a scholarly but fascinating overview of the rise and fall of this lost world, and why it still matters to us.
When I think of turn-of-the-20th-century palaeontology, names such as Othniel Charles Marsh and Edward Drinker Cope are the first to come to mind. Their infamous rivalry, known as the Bone Wars, relied heavily on field collectors who did the back-breaking labour of prospecting and quarrying for fossils. Most of these bone hunters are barely remembered, and John Bell Hatcher might very well have remained thus. This meticulous biography by American palaeontologist Lowell Dingus saves Hatcher from obscurity and documents both his hugely successful work as a bone hunter, as well as his later stellar but tragically short-lived career as a curator.
At first blush, you might think this book is part of the ongoing craze of spiritual mindfulness books. But let me refrain from snarky comments. Geologist Marcia Bjornerud does indeed want to instill a sense of mindfulness about deep time, but one that is, pardon the pun, grounded in geology. In her opinion, most of us lack an awareness of durations of important chapters in our planet’s history and of rates of change of many natural processes. As a consequence, we fail to see just how rapidly we are altering our planet. In one of the first paragraphs she eloquently writes:
“Like inexperienced but overconfident drivers, we accelerate into landscapes and ecosystems with no sense of their long-established traffic patterns, and then react with surprise and indignation when we face the penalties for ignoring natural laws”.
And with that, she had me hooked.
