This volume brings together state-of-the-art reviews of the non-biostratigraphic and biostratigraphic data that are used to define and correlate Permian time intervals. It includes analyses of Permian radio-isotopic ages, magnetostratigraphy, isotope-based stratigraphy and timescale-relevant biostratigraphy. It is the first book devoted to this subject and represents the cutting edge of Permian time-scale research.

Distinguished historians of science give an appraisal of Sir Charles Lyell's life and works, and his influence through his travels across Europe and North America. Leading geologists assess Lyell's subsequent influence on climatology, sedimentology, stratigraphy, coal geology, regional tectonics, volcanology and natural hazards. Modern geological research constructed upon Lyell's legacy illustrates its wealth, 200 years on from his birth.

In recent years dinosaurs have captured the attention of the public at an unprecedented scale. At the heart of this resurgence in popular interest is an increased level of research activity, much of which is innovative in the field of palaeontology. For instance, whereas earlier palaeontological studies emphasized basic morphologic description and taxonomic classification, modern studies attempt to examine the role and nature of dinosaurs as living animals. More than ever before, we understand how these extinct species functioned, behaved, interacted with each other and the environment, and evolved. Nevertheless, these studies rely on certain basic building blocks of knowledge, including facts about dinosaur anatomy and taxonomic relationships. One of the purposes of this volume is to unravel some of the problems surrounding dinosaur systematics and to increase our understanding of dinosaurs as a biological species. Dinosaur Systematics presents a current overview of dinosaur systematics using various examples to explore what is a species in a dinosaur, what separates genders in dinosaurs, what morphological changes occur with maturation of a species, and what morphological variations occur within a species.

Footprints in Stone is the definitive guide to the Steven C. Minkin (Union Chapel) Paleozoic Footprint Site in northwest Alabama, the discovery of whose vast quantity of 310-million-year-old fossil tetrapod footprints and other traces is one of the most significant developments in modern paleontology.
