PALEOECOLOGYPALEOECOLOGYPast, Present and FuturePaleoecology is a discipline that uses evidence from fossils to provide an understanding of ancient environments and the ecological history of life through geological time. This text covers the fundamental approaches that have provided the foundation for present paleoecological understanding, and outlines new research areas in paleoecology for managing future environmental and ecologica...

This book provides a detailed examination of ichnology during the Permian-Triassic mass extinction in China, focusing on the recovery patterns of marine trace-making organisms. It features a wealth of high-quality ichnofossil photographs and figures, offering readers a comprehensive guide to ichnotaxa identifications and descriptions from both South and North China, spanning the Late Permian to the Middle Triassic.The chapters cover critical topics such as the delayed biotic recove...

One of the most important questions we can ask about life is "Does ecology matter?" Most biologists and paleontologists are trained to answer "yes," but the exact mechanisms by which ecology matters in the context of patterns that play out over millions of years have never been entirely clear. This book examines these mechanisms and looks at how ancient environments affected evolution, focusing on long-term macroevolutionary changes as seen in the fossil record.Evolutionary paleoec...

Taphonomic bias is a pervasive feature of the fossil record. A pressing concern, however, is the extent to which taphonomic processes have varied through the ages. It is one thing to work with a biased data set and quite another to work with a bias that has changed with time. This book includes work from both new and established researchers who are using laboratory, field and data-base techniques to characterise and quantify the temporal and spatial variation in taphonomic bias. It may not...

The evolution of the Argentina Continental Margin during the Quaternary and the stratigraphic and morphosedimentary configuration responded to climatic variability, oceanographic changes, glacioeustatic fluctuations and tectono-isostatic processes, which began to impact on the margin during previous geological periods. The final modeling of the margin was achieved in the late Miocene, when the interaction between the Antarctic and North Atlantic water-masses favored climatic and oceanograp...

The book deals with the record of important Neoproterozoic to Early Palaeozoic events in southwestern Gondwana, that heralded the Cambrian explosion and the dawn of modern ecosystems. It contains a detailed account of the Neoproterozoic to Cambrian geological record in a poorly-known part of the world, which is at the same time key to understand fundamental processes at the Proterozoic-Cambrian transition. The emphasis is placed on litho-, bio-, chemostratigraphy and magmatism. The palaeoc...

In 2007, a massive, concentrated deposit of dinosaur fossils, some of theoldest ever found, were discovered in the mountain ridges of northernBritish Columbia, near an old coal mining town. The site contained thelargest number of tyrannosaur teeth ever found with another species, anunfortunate lambeousaur who¹d been scavenged by a pack of hyena-likejuvenile predators millions of years ago. The small group of paleontologistsdigging the site have had to keep its location a secret to protect ...

In this landmark work on a subject too often dismissed as paranormal or disreputable, Jeff Meldrum gives us the first book on sasquatch to be written by a scientist with impeccable academic credentials, an objective look at the facts in a field mined with hoaxes and sensationalism.Meldrum reports on the work of a team of experts from a wide variety of fields who were assembled to examine the evidence for a large, yet undiscovered, North American primate. He reviews...

The Palaeozoic or Primary Era spans a period of time ranging from 542 million to 251 million years ago. The name Paleozoic, derives from the fact that, in the past, it was considered the first geological age. The Paleozoic covers a range of about 300 million years, giving rise to many forms of life, until the appearance of thecodonts, commonly believed to be the ancestors of dinosaurs.

This ebook edition does not include illustrations.An awe-inspiring journey through the eons and across the globe, in search of visible traces of evolution in the living creatures which have survived from earlier times and whose stories speak to us of seminal events in the history of life.The history of life on Earth is far older – and far odder – than many of us realise. In ‘Survivors’, acclaimed author Richard Fortey traces this history not through fossil records, but in t...
