Our knowledge of extinct animals depends almost entirely upon the study of fossils. This richly illustrated book clothes the skeletons of dinosaurs and other Mesozoic reptiles with flesh, and shows how these fascinating animals evolved and probably lived. Expert author John L. Cloudsley-Thompson provides an interesting synthesis of current views on their ecology, physiology and behaviour, and outlines the various hypotheses that have been proposed to explain their extinction. Numerous beautiful drawings of the animals and their environment illustrate this exciting monograph.

Traces of the action of mechanical and chemical boring, scraping or crushing organisms on hard substrates appear in fossil carbonates as old as the Precambrian, providing valuable palaeoenvironmental indicators. Bioerosion has been extensively studied in tropical seas, but data from cold-temperate to polar settings remain sparse. This book presents an experimental study into the pace of carbonate degradation and the chronology of boring community development along a bathymetric gradient in high-latitude settings.

Shawnee legend tells of a herd of huge bison rampaging through the Ohio Valley, laying waste to all in their path. To protect the tribe, a deity slew these great beasts with lightning bolts, finally chasing the last giant buffalo into exile across the Wabash River, never to trouble the Shawnee again. The source of this legend was a peculiar salt lick in present-day northern Kentucky, where giant fossilized skeletons had for centuries lain undisturbed by the Shawnee and other natives of the region. In 1739, the first Europeans encountered this fossil site, which eventually came to be known...

With its massive head, enormous jaws, and formidable teeth, Tyrannosaurus rex has long been the young person's favorite creepy carnivore in the Mesozoic zoo. Nor has T. rex been ignored by the scientific community, as this new collection amply demonstrates. Scientists explore such questions as why T. rex had such small forelimbs; how the dinosaur moved; what bone pathologies tell us about life in the Cretaceous; and whether T. rex was a predator, a scavenger, or both. There are reports on newly discovered skeletons, on variation and sexual dimorphism, and how the big beasts chewed. The...

The dominant faunal elements in shallow Paleozoic oceans, echinoderms are important to understanding these marine ecosystems. Echinoderms (which include such animals as sea stars, crinoids or sea lilies, sea urchins, sand dollars, and sea cucumbers) have left a rich and, for science, extremely useful fossil record. For various reasons, they provide the ideal source for answers to the questions that will help us develop a more complete understanding of global environmental and biodiversity changes. This volume highlights the modern study of fossil echinoderms and is organized into five...

The present book combines three main aspects: five major mass extinctions; contributions on some other minor extinctions; and more importantly contributions on the current mass extinction. All three aspects are introduced through interesting studies of mass extinctions in diverse organisms ranging from small invertebrates to mammals and take account of the most accepted subjects discussing mass extinctions in insects, mammals, fishes, ostracods and molluscs.

In the past few years rapid progress has been made regarding our understanding of one of the dominant phytoplankton groups of the world's oceans: the coccolithophores. Among other initiatives, the EU-funded TMR network CODENET (Coccolithophores Evolutionary Biodiversity and Ecology Network) has provided new results and insights. These and many other findings are reviewed and synthesized in a number of individual chapters which focus on coccolithophore biology (molecular to cellular), ecology (experimental and in the ocean), evolutionary phylogeny and its impact on current and past global...

Paleopalynology, second edition, provides profusely illustrated treatment of fossil palynomorphs, including spores, pollen, dinoflagellate cysts, acritarchs, chitinozoans, scolecodonts, and various microscopic fungal and algal dispersal bodies. The book serves both as a student text and general reference work. Palynomorphs yield information about age, geological and biological environment, climate during deposition, and other significant factors about the enclosing rocks.

Extant spores and pollen are treated first, preparing the student for more difficult work with fossil...
