Horns and Beaks completes Ken Carpenter's series on the major dinosaur types. As with his volumes on armored, carnivorous, and sauropodomorph dinosaurs, this book collects original and new information, reflecting the latest discoveries and research on these two groups of animals. The Ornithopods include Iguanodon, one of the first dinosaurs ever discovered and analyzed, and perhaps the most common and best-documented group, the hadrosaurs or "duckbilled dinosaurs." The Ceratopsians include Triceratops, known for its distinctive three-horned skull and protective collar.

New discoveries of ancient vertebrates, filling in gaps in the fossil record, are quickly eroding the traditionally recognized differences between the principal groups of vertebrates for example, between dinosaurs and birds and radically changing our understanding of the evolutionary history of the major group of animals to which our species belongs. This book describes this changing scientific landscape and contributes to the revolution in our knowledge of the developmental mechanisms that underlie evolutionary transformation.

This volume presents state-of-the-art papers on important topics and methods in the analysis of vertebrate microfossil assemblages. The minute remains of animals and plants have proven very useful to paleontologists as tools for dating large fossils, describing the environments which existed at the time the fossils were deposited, and identifying and mapping the extent of local floras and faunas, among other things. Due to the large sample sizes that can be obtained, the chance to recover rare taxa is much higher than it is during a search for skeletal remains. Analysis of the data...

Phylogenetic analysis and morphometrics have been developed by biologists into rigorous analytic tools for testing hypotheses about the relationships between groups of species. This book applies these tools to paleontological data.

The fossil record is our one true chronicle of the history of life, preserving a set of macroevolutionary patterns; thus various hypotheses about evolutionary processes can be tested in the fossil record using phylogentic analysis and morphometrics.

The first book of its type, Fossils, Phylogeny, and Form will be useful in...

"A superb introduction to paleontology as it really is and how it is done, from fish to dinosaur, bird, and mammal." --Edward O. Wilson

Michael Novacek, a renowned paleontologist who has discovered important fossils on virtually every continent, is an authority on patterns of evolution and on the relationships among extinct and extant organisms. Time Traveler is his captivating account of how his boyhood enthusiasm for dinosaurs became a lifelong commitment to vanguard science. Novacek writes of the alluring perils of fieldwork with affection and discernment, and he...
