An adult great white is a big shark really big. It has been responsible for more shark bites and human deaths than any other species, according to the International Shark Attack File. This is probably because it sees us as aberrant marine mammals flailing about in the water and certainly worth an exploratory bite but a gentle mouthing from a two-tonne white shark, its jaws filled with row upon row of razor-sharp teeth, could result in a severe mauling for any victim unlucky enough to have attracted its attention.Though its danger was well known to ancient mariners, it was not until the mid-1970s that it came to occupy its current place in the popular imagination, when Jaws was unleashed on an unsuspecting public. The great white sharks reputation hit rock bottom in the wake of the Spielberg classic. But during the fifty years since the films first release, public interest in the species has sparked a renaissance in research, producing remarkable new insights into the life of this extraordinary animal.Telling the story of the great white shark from the perspectives of history, psychology and biology, White Shark is nothing less than the biography of the worlds most fascinating fish.

El reconocimiento del papel de los animales en las antiguas dietas, en las economias, politicas y los rituales, es vital para poder entender a las culturas del pasado en su totalidad. Por el otro lado, seguir las claves que se obtienen de restos de animales preteritos puede aproximarnos a entender la antigua relacion que existia entre los humanos y el mundo que les rodeaba. En respuesta a un creciente interes en el campo de la zooarqueologia, este libro presenta investigaciones que representan a las multiples culturas y regiones de Mesoamerica, tratando especificamente los aspectos mas recurrentes en la literatura zooarqueologica. Desde el punto de vista geografico, los ensayos reunidos aqui informan acerca del uso de animals por parte de los pueblos indigenas de toda el area mesoamericana, ubicada entre los confines nortenos de Mexico y la frontera sur, en Centroamerica. Esto incluye culturas tan diversas como los olmecas, mayas, mixtecos, zapotecos e indigenas de Centroamerica. El marco temporal del libro se extiende desde el Preclasico y Clasico, sobre el Posclasico, los tiempos coloniales e historicos, hasta la epoca actual. Los capitulos del libro, escritos por expertos en la materia de la zooarqueologia mesoamericana, proporcionan un fondo de conocimiento general e importante acerca del uso domestico y ritual durante los tiempos tempranos y clasicos de Mesoamerica y Centroamerica, pero abarcan tambien aspectos especificos de la relacion entre humanos y animales, tales como la domesticacion temprana y el simbolismo de animales, asi como otros puntos aun pobremente entendidos, relacionados a la tafonomia y a la metodologia zooarqueologica. English-language version also available (ISBN 978-1-937040-05-5).

Recognition of the role of animals in ancient diet, economy, politics, and ritual is vital to understanding ancient cultures fully, while following the clues available from animal remains in reconstructing environments is vital to understanding the ancient relationship between humans and the world around them. In response to the growing interest in the field of zooarchaeology, this volume presents current research from across the many cultures and regions of Mesoamerica, dealing specifically with the most current issues in zooarchaeological literature. Geographically, the essays collected here index the different aspects of animal use by the indigenous populations of the entire area between the northern borders of Mexico and the southern borders of lower Central America. This includes such diverse cultures as the north Mexican hunter-gatherers, the Olmec, Maya, Mixtec, Zapotec, and Central American Indians. The time frame of the volume extends from the earliest human occupation, the Preclassic, Classic, Postclassic, and Colonial manifestations, to recent times. The books chapters, written by experts in the field of Mesoamerican zooarchaeology, provide important general background on the domestic and ritual use of animals in early and classic Mesoamerica and Central America, but deal also with special aspects of human-animal relationships such as early domestication and symbolism of animals, and important yet otherwise poorly represented aspects of taphonomy and zooarchaeological methodology. Spanish-language version also available (ISBN 978-1-937040-12-3).
