The only way to experience them is rockwise, to read the imprints in the frozen sand and to imagine a disappeared Earth. You can never visit the environments through which titanic dinosaurs strode, never walk on their soil nor swim in their water. The geological history of the Earth stretches back about 4.5 billion years… The landscapes that have existed over geological time, revealed by the palaeontological record, are varied and, at times, quite other to the world of today… Those worlds, those otherlands, cannot be visited – at least, not in a physical sense. “The worlds of the past can sometimes seem unimaginably distant. It is a breathtaking a surprisingly emotional narrative about the persistence of life, the fragility of seemingly permanent ecosystems, and the scope of deep time, all of which have something to tell us about our current crisis.

In novelistic prose that belies the breadth of his research, he illustrates how ecosystems are formed how species die out and are replaced and how species migrate, adapt, and collaborate. But the fossil record shows us that this sort of wholesale change is not only possible but has repeatedly happened throughout Earth history.Įven as he operates on this broad canvas, Halliday brings us up close to the intricate relationships that defined these lost worlds. The thought that something as vast as the Great Barrier Reef, for example, with all its vibrant diversity, might one day soon be gone sounds improbable. Otherlands also offers us a vast perspective on the current state of the planet. It takes us from the savannahs of Pliocene Kenya to watch a python chase a group of australopithecines into an acacia tree to a cliff overlooking the salt pans of the empty basin of what will be the Mediterranean Sea just as water from the Miocene Atlantic Ocean spills in into the tropical forests of Eocene Antarctica and under the shallow pools of Ediacaran Australia, where we glimpse the first microbial life.

This book is an exploration of the Earth as it used to exist, the changes that have occurred during its history, and the ways that life has found to adapt―or not. In Otherlands, Halliday makes sixteen fossil sites burst to life on the page. The past is past, but it does leave clues, and Thomas Halliday has used cutting-edge science to decipher them more completely than ever before.
