Book Description
This volume, aimed at the general reader, presents life and times of the amazing animals that inhabited Earth more than 500 million years ago. The Cambrian Period was a critical time in Earth's history. During this immense span of time nearly every modern group of animals appeared. Although life had been around for more than 2 million millennia, Cambrian rocks preserve the record of the first appearance of complex animals with eyes, protective skeletons, antennae, and complex ecologies. Grazing, predation, and multi-tiered ecosystems with animals living in, on, or above the sea floor became common. The cascade of interaction led to an ever-increasing diversification of animal body types. By the end of the period, the ancestors of sponges, corals, jellyfish, worms, mollusks, brachiopods, arthropods, echinoderms, and vertebrates were all in place. The evidence of this Cambrian "explosion" is preserved in rocks all over the world, including North America, where the seemingly strange animals of the period are preserved in exquisite detail in deposits such as the Burgess Shale in British Columbia. Cambrian Ocean World tells the story of what is, for us, the most important period in our planet's long history.

Book Description
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.

Book Description
The contributions in this book explore several geologically significant sites and, in doing so, acknowledge and explore not just the geological exposures themselves, but also the people and issues that are fundamentally intertwined with the history of our science and its impact on our society. Through selective examples of outcrops and locales integral to the history of geology, we explore the evolution of modern geology, as well as the geodiversity and geoheritage of our planet. While the volume is far from comprehensive, the chapters contained herein detail a range for geoheritage value, scale of geoheritage sites and potential for geoheritage opportunities that will promote a broader, richer understanding of the complexity of the geoheritage of Earth. Importantly, many chapters offer a cautionary tale of sites almost lost to posterity and submit their take-away lessons for community mobilization towards geoheritage site protection.
