"There is much to love between this book’s covers. . . . There are many eureka moments in Life Sculpted—and some truly beautiful ones."—Eugenia Bone, Wall Street Journal Meet the menagerie of lifeforms that dig, crunch, bore, and otherwise reshape our planet. Did you know elephants dig ballroom-sized caves alongside volcanoes? Or that parrotfish chew coral reefs and poop sandy beaches? Or that our planet once hosted a five-ton dinosaur-crunching alligator cousin? In fact, almost since its fascinating start, life was boring. Billions of years ago bacteria, algae, and fungi began breaking down rocks in oceans, a role they still perform today. About a half-billion years ago, animal ancestors began drilling, scraping, gnawing, or breaking rocky seascapes. In turn, their descendants crunched through the materials of life itself—shells, wood, and bones. Today, such “bioeroders” continue to shape our planet—from the bacteria that devour our teeth to the mighty moon snail, always hunting for food, as evidenced by tiny snail-made boreholes in clams and other moon snails. There is no better guide to these lifeforms than Anthony J. Martin, a popular science author, paleontologist, and co-discoverer of the first known burrowing dinosaur. Following the crumbs of lichens, sponges, worms, clams, snails, octopi, barnacles, sea urchins, termites, beetles, fishes, dinosaurs, crocodilians, birds, elephants, and (of course) humans, Life Sculpted reveals how bioerosion expanded with the tree of life, becoming an essential part of how ecosystems function while reshaping the face of our planet. With vast knowledge and no small amount of whimsy, Martin uses paleontology, biology, and geology to reveal the awesome power of life’s chewing force. He provokes us to think deeply about the past and present of bioerosion, while also considering how knowledge of this history might aid us in mitigating and adapting to climate change in the future. Yes, Martin concedes, sometimes life can be hard—but life also makes everything less hard every day.

Have you ever wondered what left behind those prints and tracks on the seashore, or what made those marks or dug those holes in the dunes? Life Traces of the Georgia Coast is an up-close look at these traces of life and the animals and plants that made them. It tells about how the tracemakers lived and how they interacted with their environments. This is a book about ichnology (the study of such traces) and a wonderful way to learn about the behavior of organisms, living and long extinct. Life Traces presents an overview of the traces left by modern animals and plants in this biologically rich region; shows how life traces relate to the environments, natural history, and behaviors of their tracemakers; and applies that knowledge toward a better understanding of the fossilized traces that ancient life left in the geologic record. Augmented by illustrations of traces made by both ancient and modern organisms, the book shows how ancient trace fossils directly relate to modern traces and tracemakers, among them, insects, grasses, crabs, shorebirds, alligators, and sea turtles. The result is an aesthetically appealing and scientifically grounded book that will serve as source both for scientists and for anyone interested in the natural history of the Georgia coast.

With this collection of essays, Anthony J. Martin invites us to investigate animal and human traces on the Georgia coast and the remarkable stories these traces, both modern and fossil, tell us. Readers will learn how these traces enabled geologists to discover that the remains of ancient barrier islands still exist on the lower coastal plain of Georgia, showing the recession of oceans millions of years ago.First, Martin details a solid but approachable overview of Georgia barrier island ecosystems - maritime forests, salt marshes, dunes, beaches - and how these ecosystems are as much a product of plant and animal behavior as they are of geology. Martin then describes animal tracks, burrows, nests, and other traces and what they tell us about their makers. He also explains how trace fossils can document the behaviors of animals from millions of years ago, including those no longer extant.Next, Martin discusses the relatively scant history - scarcely five thousand years - of humans on the Georgia coast. He takes us from the Native American shell rings on Sapelo Island to the cobbled streets of Savannah paved with the ballast stones of slave ships. He also describes the human introduction of invasive animals to the coast and their effects on native species.Finally, Martin's epilogue introduces the sobering idea that climate change, with its resultant extreme weather and rising sea levels, is the ultimate human trace affecting the Georgia coast. Here he asks how the traces of the past and present help us to better predict and deal with our uncertain future.
