Book Description
For most of the past 300 million years, the world’s continents were interlinked as the supercontinents Pangaea and then Gondwana. Around 50 million years ago, Australia tore itself free from Antarctica to become the huge, splendidly isolated island it is today. Over time, its creatures began to evolve in ways not seen anywhere else on Earth, with tree-climbing crocodiles, gigantic venomous lizards, walking omnivorous bats and flesh-eating kangaroos roaming the continent. Prehistoric Australasia: Visions of Evolution and Extinction presents some of the most extraordinary creatures the world has ever seen – all unique to Australia, New Guinea, New Zealand and their surrounding islands. Over 100 meticulously painted panoramas by palaeoartist Peter Schouten are accompanied by descriptions of the unique environments and features of these animals, written by four of Australia’s foremost palaeontologists. This book explores the nature and timing of extinction events in the Southern Hemisphere, considers whether some of these losses might be able to be reversed, and how we can use the fossil record to help save today’s critically endangered species. Through stunning artwork and fascinating text, Prehistoric Australasia brings this globally unique transformation over time to glorious, colourful life.

Book Description
In the days when dinosaurs dominated the earth, their marine counterparts - every bit as big and ferocious - reigned supreme in prehistoric seas. In this book, Richard Ellis takes us back to the Mesozoic era to resurrect the fascinating lives of these giant seagoing reptiles. fierce predators, speculates on their habits, and tells how they eventually became extinct - or did they? He traces the 200-million-year history of the great ichthyosaurs, plesiosaurs and mosasaurs who swam the ancient oceans - and who may, according to some, still frequent the likes of Loch Ness. animal that looked like a crocodile crossed with a shark the size of a small yacht. With its impossibly long neck, Plesiosaurus conybeari has been compared to a giant snake threaded through the body of a turtle. At a length of nearly 60 feet, Mosasaurus hoffmanni boasted powerful jaws that could crunch up even the hardest-shelled giant sea turtle. And Kronosaurus queenslandicus, perhaps the most formidable of the lot, had a skull nine feet long - more than twice that of Tyrannosaurus rex - with teeth to match. reconstruct their lives and habitats. Their fossils have been found all over the world - in Europe, Australia, Japan and even Kansas - in lands that once lay on the floors of Jurassic and Triassic seas. Along the way, the book also provides intriguing insights into and entertaining tales about the work, discoveries and competing theories that compose the world of vertebrate paleontology. The text is also accompanied by Ellis' own illustrations of how these creatures probably appeared and, through these likenesses, we are invited to speculate on their locomotion, their predatory habits and their lifestyles.

Book Description
A critical examination of James Lovelock's controversial Gaia hypothesis One of the enduring questions about our planet is how it has remained continuously habitable over vast stretches of geological time despite the fact that its atmosphere and climate are potentially unstable. James Lovelock's Gaia hypothesis posits that life itself has intervened in the regulation of the planetary environment in order to keep it stable and favorable for life. First proposed in the 1970s, Lovelock's hypothesis remains highly controversial and continues to provoke fierce debate. On Gaia undertakes the first in-depth investigation of the arguments put forward by Lovelock and others—and concludes that the evidence doesn't stack up in support of Gaia. Toby Tyrrell draws on the latest findings in fields as diverse as climate science, oceanography, atmospheric science, geology, ecology, and evolutionary biology. He takes readers to obscure corners of the natural world, from southern Africa where ancient rocks reveal that icebergs were once present near the equator, to mimics of cleaner fish on Indonesian reefs, to blind fish deep in Mexican caves. Tyrrell weaves these and many other intriguing observations into a comprehensive analysis of the major assertions and lines of argument underpinning Gaia, and finds that it is not a credible picture of how life and Earth interact. On Gaia reflects on the scientific evidence indicating that life and environment mutually affect each other, and proposes that feedbacks on Earth do not provide robust protection against the environment becoming uninhabitable—or against poor stewardship by us.
