Hilltops surrounded by farmland in southern Wisconsin turn out to be the eroded remnants of an ancient archipelago. An island…
in the Yellow Sea where Korean tourists flock is the peak of a flooded mountain rising from a drowned continental shelf. From a mountaintop shrine to Genghis Khan in Inner Mongolia, the silhouette of a Silurian seascape can be spotted. On the shores of Hudson Bay, where polar bears patrol the Arctic tundra, a close look unveils what was a tropical coastline encrusted with corals nearly 450 million years ago.The geologist Markes E. Johnson invites readers on a journey through deep time to find the traces of ancient islands. He visits a dozen sites around the globe, looking above and below today’s waterlines to uncover how landscapes of the past are preserved in the present. Going back 500 million years to the Cambrian through the Pleistocene 125,000 years ago, this book reconstructs how “paleoislands” appeared under different climatic conditions and environmental constraints. Finding vestiges of prehistoric ecologies, Johnson emphasizes the complexity of island ecosystems and the importance of preserving these significant sites.Inviting and accessible, this book is a travelogue that takes readers through time as well as space. Islands in Deep Time shares the adventure of exploring striking locations across geologic eras and issues a passionate call for their conservation.Dinosaur Behavior: An Illustrated Guide

A fascinating study of the thousands of new animal species that walked in the footsteps of the dinosaurs—and the climate…
changes that brought them forth. The fascinating group of animals called dinosaurs became extinct some 65 million years ago (except for their feathered descendants). In their place evolved an enormous variety of land creatures, especially mammals, which in their way were every bit as remarkable as their Mesozoic cousins. The Age of Mammals, the Cenozoic Era, has never had its Jurassic Park, but it was an amazing time in earth&’s history, populated by a wonderful assortment of bizarre animals. The rapid evolution of thousands of species of mammals brought forth many incredible creatures―including our own ancestors. Their story is part of a larger story of new life emerging from the greenhouse conditions of the Mesozoic, warming up dramatically about 55 million years ago, and then cooling rapidly so that 33 million years ago the glacial ice returned. The earth&’s vegetation went through equally dramatic changes, from tropical jungles in Montana and forests at the poles. Life in the sea underwent striking evolution reflecting global climate change, including the emergence of such creatures as giant sharks, seals, sea lions, dolphins, and whales. Engaging and insightful, After the Dinosaurs is a book for everyone who has an abiding fascination with the remarkable life of the past.Land of Hunters: Earth's Most Fearsome Predators

252 to 66 million years ago, dinosaurs ruled the land, but the ocean deeps were roiling with equally spectacular reptiles—including giant predators. This richly illustrated, authoritative, and accessible book introduces readers to the world of these fascinating marine animals, whose predecessors returned to the seas a few million years after the first vertebrates emerged from the water. As we meet ichthyosaurs, plesiosaurs, mosasaurs, and many others, we learn about the astonishing anatomical, physiological, and behavioral adaptations that enabled these reptiles to become ocean dwellers again. We also learn about their living descendants, including sea turtles and sea snakes. Featuring stunning artwork depicting these prehistoric ocean creatures and photographs of their fossil remains, this book invites readers to discover the enthralling past of marine reptiles in all their extraordinary diversity.Alfred Russell Wallace Contributions to the theory of Natural Selection, 1870, and Charles Darwin and Alfred Wallace , 'On the Tendency of Species to form Varieties' (The evolution Debate, 1813-1870 Ser.)

their Australian cousins. His suggestion was that the two continents had split before the better adapted mammals had evolved in Asia. The isolated Australian marsupials were able to thrive, whilst those in Asia were driven to extinction by competition from more advanced mammals. This led to his theory of natural selection, which he presented to the Linnean Society in 1858 with Charles Darwin. This volume reprints those papers presented to the Linnean Society.Charles Lyell's argument in this classic volume is that the processes of nature are slow and uniform, and that the…
