Book Description
Pterosaurs were a peculiar group of Mesozoic vertebrates, which acquired the ability to fly in an original way, using a membrane attached to a single finger of the hand. Ever since the first description of a pterosaur skeleton in 1784, these remarkable animals have elicited much discussion and controversy among palaeontologists, and many basic questions about their origin, evolution and biology remain disputed. In the last few years, interest in pterosaurs has been revived by numerous discoveries of new and sometimes remarkably preserved specimens, which have enlarged and changed our picture of this group. The volume begins with descriptions of several new pterosaurs from the Triassic, Jurassic and Cretaceous of Europe, North and South America, and Africa. Following this, alternative hypotheses of pterosaur phytogeny and evolution are put forward. Several papers discuss the functional anatomy of pterosaurs and its implications for aerial locomotion. The study of pterosaur footprints provides important new evidence concerning their terrestrial locomotion, and this approach is used in several contributions. A developing aspect of pterosaur research is bone histology, as shown by the final papers in this collection.

Book Description
Dinosaurs and other prehistoric animals have always fascinated people but they pose vast problems for the artist. How do you go about recreating the anatomy and behaviour of a creature we've never seen? How can we restore landscapes long lost to time? And where does the boundary between palaeontology - the science of understanding fossils- and artistic licence lie? In this outstanding book, Mark Witton shares his detailed paintings and great experience of drawing and painting extinct species. The approaches used in rendering these impressive creatures are discussed and demonstrate the problems, as well as the unexpected freedoms, that palaeontological artists are faced with. The book showcases over ninety scientifically credible paintings of some of the most spectacular animals in the Earth's history, as well as may less familiar species. Mark explains how each image was created with details of the artistic process, scientific grounding and collaborations between researchers and discusses the methods and goals of palaeoartistry - the recreation of extinct animals and landscapes in art. This book will be of great interest to palaeontological artists, researchers, museum curators, dinosaur enthusiasts and fossil hunters. Superbly illustrated with 90 paintings.

Book Description
With more than 500 species distributed all around the Northern Hemisphere, the genus Quercus L. is a dominant element of a wide variety of habitats including temperate, tropical, subtropical and mediterranean forests and woodlands. As the fossil record reflects, oaks were usual from the Oligocene onwards, showing the high ability of the genus to colonize new and different habitats. Such diversity and ecological amplitude makes genus Quercus an excellent framework for comparative ecophysiological studies, allowing the analysis of many mechanisms that are found in different oaks at different level (leaf or stem). The combination of several morphological and physiological attributes defines the existence of different functional types within the genus, which are characteristic of specific phytoclimates. From a landscape perspective, oak forests and woodlands are threatened by many factors that can compromise their future: a limited regeneration, massive decline processes, mostly triggered by adverse climatic events or the competence with other broad-leaved trees and conifer species. The knowledge of all these facts can allow for a better management of the oak forests in the future.
