Nature through Time
This book simulates a historical walk through nature, teaching readers about the biodiversity on Earth in various eras with a focus on past terrestrial environments. Geared towards a student audience, using simple terms and avoiding long complex explanations, the book discusses the plants and animals that lived on land, the evolution of natural systems, and how these biological systems changed over time in geological and paleontological contexts. With easy-to-understand and scientifically accurate and up-to-date information, readers will be guided through major biological events from the Earth's past. The topics in the book represent a broad paleoenvironmental spectrum of interests and educa...
When the Land Turned Green
Deep in the wilderness of northern Maine in the mid-1950s, a Harvard PhD student is wading down a mountain stream into a remote valley. He is taking his first steps to map the geology of 300 square miles of Baxter State Park. He soon discovers a series of unusually shaped rock outcrops—part of an unknown geologic formation, hundreds of millions of years old, still mystifying today because of its relative lack of change despite nearby volcanic activity and massive land movement. Wading on, he has another surprise. In a thin layer of black shale beside the stream, he finds a small fossil of a plant. Little does he know, but his discovery of Perticaquadrifaria will help scientists unlock the ...
Sedimentation of Organic Particles
This book presents research work on the sedimentation of components of palynofacies and details their importance for sequence stratigraphy and the interpretation of ancient biologic and geologic environments. After a comprehensive introduction, later chapters look at palynosedimentation in modern environments, the reconstruction of terrestrial vegetation, the application of the data to sequence stratigraphy and several chapters deal with various quantitative methods and their specific applications in the subject.
Terrestrial Ecosystems Through Time
Breathtaking in scope, this is the first survey of the entire ecological history of life on land—from the earliest traces of terrestrial organisms over 400 million years ago to the beginning of human agriculture. By providing myriad insights into the unique ecological information contained in the fossil record, it establishes a new and ambitious basis for the study of evolutionary paleoecology of land ecosystems. A joint undertaking of the Evolution of Terrestrial Ecosystems Consortium at the National Museum of Natural History, Smithsonian Institution, and twenty-six additional researchers, this book begins with four chapters that lay out the theoretical background and methodology of the s...
Paleoecology
PALEOECOLOGY PALEOECOLOGY Past, Present and Future Paleoecology 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 ecological change. Topics include the use of actualism in paleoecology, development of paleoecological models for paleoenvironmental reconstruction, taphonomy and exceptional fossil preservation, evolutionary paleoecology and ecological change through time, and conserv...
When Life Nearly Died
It is common knowledge that the dinosaurs were wiped out by a meteorite impact 65 million years ago that killed half of all species then living, but far less well-known is a much greater catastrophe that took place 251 million years ago: at least 90 per cent of life was destroyed, including sabre-toothed reptiles and their rhinoceros-sized prey, as well as vast numbers of fish and other species in the sea. This book documents not only what happened during this gigantic mass extinction, but also the recent reviving of the idea of catastrophism. Was the end-Permian event caused by the impact of a huge meteorite or comet, or by prolonged volcanic eruption in Siberia? The evidence has been accum...
