""Mesozoic Birds is the first book to bring together world-renowned specialists on fossil birds and their importance to avian origins and, more importantly, it stresses a unified approach (cladistics) and presents the most anatomically detailed analyses available to date. No other study or collection of studies has ever done so much. How could the project not be welcomed by its audience of paleontologists, ornithologists, and evolutionary biologists!"--David Weishampel, editor of "The Dinosauria "This is the first comprehensive volume dedicated to the relationships and evolution of the birds that lived during the Age of Dinosaurs. Its wealth of information and its diversity of viewpoints will ensure that this indispensable volume is used and discussed for many years to come."--Kevin Padian, University of California, Berkeley Our knowledge of the origin and early evolution of birds has exploded in the past ten to fifteen years. In the 1990s alone, scientists became aware of approximately three times more species of early birds than were previously known, marking the first 85 million years of avian development as a period of remarkable species diversity. Assembling work by an international group of renowned scientists, "Mesozoic Birds: Above the Heads of Dinosaurs "is the most authoritative and up-to-date source on early avian evolution currently available. This unique resource provides a comprehensive examination of the known fossil record and is also an unparalleled guide to the fast-paced developments in current research. "Mesozoic Birds: Above the Heads of Dinosaurs "covers a wide range of topics, including discussions of avian origins, the fossil record of feathers and footprints, bone histology, and locomotor evolution. Controversial taxa such as "Protoavis, Caudipteryx, "and "Mononykus "receive special treatment. But the heart of the volume presents the anatomy, relationships, and paleobiology of the undisputed Mesozoic aviary. Some of the book''s most exciting features are the new definitive descriptions and illustrations of taxa that previously have received only brief notice, such as the alvarezsaurid "Shuvuuia; "the enantiornithines "Sinornis; Eoalulavis, Vorona, "and "Patagopteryx; "and

Este volumen recoge las conferencias impartidas en las VIII Jornadas Aragonesas de Paleontología y otras contribuciones en homenaje al profesor Peter Carls. El personaje es un magnífico exponente del Leitmotiv de estas Jornadas, La cooperacion internacional en la Paleontologia española. Siguiendo este lema, se ha reunido una gran cantidad de datos historicos hasta ahora dispersos, una tarea necesaria al comienzo de un nuevo siglo. En el libro se expresa tambien un sentido reconocimiento a tres relevantes cientificos europeos ya desaparecidos, los doctores Remmmert Daams, Otto F. Geyer y Wolfgang Hammann, que dedicaron su vida a la cooperacion paleontologica en Aragon.

The story of the evolution of the vertebrates, the animals with backbones, is fascinating. There is currently an explosion of new research ideas in the field - the closest fossil relatives of the vertebrates, dramatic new fish specimens unlike anything now living, the adaptations required for the move on to land, the relationships of the early amphibians and reptiles, the origins and biology of the dinosaurs, the role of mass extinction in vertebrate evolution, new Mesozoic birds, the earliest mammals, ecology and mammalian diversification, the origins and evolution of human beings. This book presents a complete outline of the history of the vertebrates, based on the latest studies by palaeontologists around the world. The work is international in scope, and new material included here for the first time come from North and South America, Australia, Europe, China, Africa, and Russia. A key aim of the book is to show how vertebrate palaeontologists obtain their information. There is an illustrated account of how to dig up a dinosaur, and how to interpret the bones.In addition, detailed case studies are presented, which show how palaeontologists study taphonomy, exceptional preservation, form and function of bizarre animals, and reconstruct phylogeny from cladistic analyses of morphological and molecular data. The new edition is extensively revised, and there is a great deal of new material based on work in the 1990s. There is a new chapter on how to study fossil vertebrates. A further major change is that more emphasis has been given to the cladograms. They are set apart from the body of the text, and full lists of diagnostic characters are now given. The book is designed for palaeontology courses in biology and geology departments. It is also aimed at the enthusiast who wants to experience the real flavour of how leading palaeontologists design their research programmes and carry out multidisciplinary studies of ancient vertebrates. The book has a strong phylogenetic focus, and this makes it an up-to-date source of the latest broad-scale systematic data on vertebrate evolution.

La vida en una charca temporal y anónima, contemplada desde el punto de vista de los sapos parteros comunes que le confían el futuro de su progenie, abre el libro con un relato inmediato, escrito al hilo de la actualidad. El recuerdo de la visita lejana a un abrevadero habitado por tres de nuestras cuatro especies de tritones, centro de un ecosistema a escala de acuario, quizá desaparecido por la acelerada transformación del territorio, lo despide. Entre ambos extremos cabe un dilatado recorrido geográfico y temporal por lagunas, turberas, estuarios, lagos, embalses y estanques, representativo de los distintos ambientes palustres y lacustres que concurren en Asturias. Una ruta didáctica que explica cómo son y cómo funcionan humedales y lagos; cómo se originaron y cómo han ido evolucionando a lo largo del tiempo; qué los distingue de otros paisajes del agua; qué tipo de flora y fauna los habita.
