Book Description
Pterosaurs or flying reptiles were the first vertebrates to evolve flight. These distant relatives of modern reptiles and dinosaurs lived from the Late Triassic (over 200 million years ago) to the end of the Cretaceous (about 65 million years ago) a span of some 135 million years. When they became extinct, no relatives survived them and as a result these prehistoric animals cannot readily be compared with our modern-day fauna. So what do we know of these highly succsessful animals? The present summary answers this and many more questions based on the most recent results of modern scientific research. After a short introduction to palaeontology as a science and its history related to pterosaurs, it explains what pterosaurs were, when and where they lived, and what they looked like. Topics such as disease, injury and reproduction are also discussed. Separated from this text are 'Mark explains' boxes. Each of these explanations puts one specific species in the spotlight and focuses on its lifestyle. They show how diverse pterosaurs were, from small insectivorous animals with a wingspan of nearly 40 centimetres to the biggest flying animals ever to take to the air, with wingspans of over 10 metres and with a way of life comparable to modern-day storks. The text is illustrated with many full colour photographs and beautiful palaeo-art prepared by experts in the field.

Book Description
With the onward march of science and technology, and the continuing quest for improvement, there is a growing curiosity about the world around us. Close examination of structures in nature can be rewarding and surprising Nature has shown an extraordinary capacity to develop dynamic structures and systems over many millions of years and there is still much to be learnt. Aimed at providing researchers in this subject with fresh impetus and inspiration, this book consists of papers presented at the Fifth International Conference on Design and Nature. The contributions reflect the rich variety of work currently taking place around the world and cover the following topics: Nature and Architecture; Mechanics in Nature; Natural Materials and Processing; Solutions from Nature; Biomimetics; Biomimetics and Bioinspiration; Biocapacity; Education in Design and Nature, and Helical Design in Nature.

Book Description
Ask anybody what superpower they wished to possess and odds are the answer just might be "the ability to fly." What is it about soaring through the air held up by the power of one's own body that has captivated humans for so long? David Alexander examines the evolution of flight in the only four animals to have evolved this ability: insects, pterosaurs, birds, and bats. With an accessible writing style grounded in rigorous research, Alexander breaks new ground in a field that has previously been confined to specialists. While birds have received the majority of attention from flight researchers, Alexander pays equal attention to all four groups of flyers-something that no other book on the subject has done before now. In a streamlined and captivating way, David Alexander demonstrates the links between the tiny 2-mm thrip and the enormous albatross with the 12 feet wingspan used to cross oceans. The book delves into the fossil record of flyers enough to satisfy the budding paleontologist, while also pleasing ornithologists and entomologists alike with its treatment of animal behavior, flapping mechanisms, and wing-origin theory. Alexander uses relatable examples to draw in readers even without a natural interest in birds, bees, and bats. He takes something that is so off-limits and unfamiliar to humans-the act of flying-and puts it in the context of experiences that many readers can relate to. Alexander guides readers through the anomalies of the flying world: hovering hummingbirds, unexpected gliders (squirrels, for instance), and the flyers that went extinct (pterosaurs). Alexander also delves into wing-origin theory and explores whether birds entered the skies from the trees down (as gliders) or from the ground up (as runners) and uses the latest fossil evidence to present readers with an answer.

Book Description
Palaeontology, the scientific study of fossils, has developed from a descriptive science to an analytical science used to interpret relationships between Earth and life history. This book provides a comprehensive and thematic treatment of applied palaeontology, covering the use of fossils in the ordering of rocks in time and in space, in biostratigraphy, palaeobiology and sequence stratigraphy. Robert Wynn Jones presents a practical workflow for applied palaeontology, including sample acquisition, preparation and analysis, and interpretation and integration. He then presents numerous case studies that demonstrate the applicability and value of the subject to areas such as petroleum, mineral and coal exploration and exploitation, engineering geology and environmental science. Specialist applications outside of the geosciences (including archaeology, forensic science, medical palynology, entomopalynology and melissopalynology) are also addressed. Abundantly illustrated and referenced, Applications of Palaeontology provides a user-friendly reference for academic researchers and professionals across a range of disciplines and industry settings.

Book Description
Nature's Machines: An Introduction to Organismal Biomechanics presents the fundamental principles of biomechanics in a concise, accessible way while maintaining necessary rigor. It covers the central principles of whole-organism biomechanics as they apply across the animal and plant kingdoms, featuring brief, tightly-focused coverage that does for biologists what H. M. Frost's 1967 Introduction to Biomechanics did for physicians. Frequently encountered, basic concepts such as stress and strain, Young's modulus, force coefficients, viscosity, and Reynolds number are introduced in early chapters in a self-contained format, making them quickly available for learning and as a refresher. More sophisticated, integrative concepts such as viscoelasticity or properties of hydrostats are covered in the later chapters, where they draw on information from multiple earlier sections of the book. Animal and plant biomechanics is now a common research area widely acknowledged by organismal biologists to have broad relevance. Most of the day-to-day activities of an animal involve mechanical processes, and to the extent that organisms are shaped by adaptive evolution, many of those adaptations are constrained and channelized by mechanical properties. The similarity in body shape of a porpoise and a tuna is no coincidence. Many may feel that they have an intuitive understanding of many of the mechanical processes that affect animals and plants, but careful biomechanical analyses often yield counterintuitive results: soft, squishy kelp may be better at withstanding pounding waves during storms than hard-shelled mollusks; really small swimmers might benefit from being spherical rather than streamlined; our bones can operate without breaking for decades, whereas steel surgical implants exhibit fatigue failures in a few months if not fully supported by bone. - Offers organismal biologists and biologists in other areas a background in biomechanics to better understand the research literature and to explore the possibility of using biomechanics approaches in their own work - Provides an introductory presentation of the everyday mechanical challenges faced by animals and plants - Functions as recommended or required reading for advanced undergraduate biology majors taking courses in biomechanics, supplemental reading in a general organismal biology course, or background reading for a biomechanics seminar course
