The Paleocene Ravenscrag Formation of southwestern Saskatchewan, Canada, is a lignite-bearing clay, silt, and sand unit which, in places, bears abundant, well preserved plant fossils. These sediments conformably overlie Maastrichtian dinosaur-bearing deposits and are interpreted as including the earliest Paleocene. Examination of the fossil materials at the Ravenscrag Butte study site indicate that the depositional environment was that of a broad alluvial plain dominated by meandering streams, ponds, swamps, and lowland forests. The paleoclimate was mesothermal, humid, and without a dry season. Rain was abundant and frost, if it occurred, was rare. A mean annual temperature of about 150C and mean annual range in temperature of 230C are proposed for the region giving an effective temperature of 140C and an equability of M 49. Forty-five distinct fossil plant species are identified and described from these sediments, with an additional 20 types of fossil remains described. The study of these fossil plants indicates that during earliest Paleocene time this region of southwestern Saskatchewan was covered with the lush vegetation of a mainly broadleaf deciduous local flora.

This book provides up-to-date coverage of fossil plants from Precambrian life to flowering plants, including fungi and algae. It begins with a discussion of geologic time, how organisms are preserved in the rock record, and how organisms are studied and interpreted and takes the student through all the relevant uses and interpretations of fossil plants. With new chapters on additional flowering plant families, paleoecology and the structure of ancient plant communities, fossil plants as proxy records for paleoclimate, new methodologies used in phylogenetic reconstruction and the addition of new fossil plant discoveries since 1993, this book provides the most comprehensive account of the geologic history and evolution of microbes, algae, fungi, and plants through time. * Major revision of a 1993 classic reference * Lavishly illustrated with 1,800 images and user friendly for use by paleobotanists, biologists, geologists and other related scientists * Includes an expanded glossary with an extensive up-to-date bibliography and a comprehensive index * Provides extensive coverage of fungi and other microbes, and major groups of land plants both living and extinct

The plant fossil record indicates that the genus Metasequoia was widely distributed throughout the Northern Hemisphere from the early Late Cretaceous to the Plio-Pleistocene. Today the genus has shrunk to one species with approximately 5,000 mature individuals in southeastern China’s Xiahoe Valley. This book distills the current understanding of the biology, ecology and physiology of fossil and living Metasequoia, current research directions and problems that remain unresolved.

This book is a unique and integrated account of the history of North American vegetation and paleoenvironments over the past 70 million years. It includes discussions of the modern plant communities, causal factors for environmental change, biotic response, and methodologies. The history reveals a North American vegetation that is vast, immensely complex, and dynamic.

Fifty million years ago, the Arctic Ocean was a warm sea, bounded by lush vegetation of the warm-temperate shores of Scandinavia, Siberia, Alaska and the Northwest Territories. Wind and storms were rare because Atlantic weather systems had not developed but, as today, polar day length added a hostile element to this otherwise tranquil climate. With the aid of scientists from all the countries close to the Arctic Circle, this book describes the palaeontology, the statistical analysis of vegetational features, comparisons with atmospheric, marine, and geological features and some of the first models of plant migration developed from newly constructed databases.

This book is designed as a source and reference for people interested in the history and fossil record of North American tertiary mammals. Each chapter covers a different family or order, and includes information on anatomical features, systematics, the distribution of the genera and species at different fossil localities, and a discussion of their paleobiology. Many of these groups have never been covered in this fashion before.

Transformative Paleobotany: Papers to Commemorate the Life and Legacy of Thomas N. Taylor features the broadest possible spectrum of topics analyzing the structure, function and evolution of fossil plants, microorganisms, and organismal interactions in fossil ecosystems (e.g., plant paleobiography, paleoecology, early evolution of land plants, fossil fungi and microbial interactions with plants, systematics and phylogeny of major plant and fungal lineages, biostratigraphy, evolution of organismal interactions, ultrastructure, Antarctic paleobotany). The book includes the latest research from top scientists who have made transformative contributions. Sections are richly illustrated, well concepted, and characterize and summarize the most up-to-date understanding of this respective and important field of study. Features electronic supplements, such as photographs, diagrams, tables, flowcharts and links to other websites Includes in-depth illustrations with diagrams, flowcharts and photographic plates (many in color for enhanced utility), tables and graphs

"Illustrates some of the more complete and recognizable megaplants from Upper Cretaceous and Paleocene of Western Canada. They represent four successive plant assemblages or floras, which, in conjunction with associated and intervening faunal assemblages, permit age correlations of rock units within a province or region, and generalized age assignments in the European geological time-scale, such as: Cenomanian; Santonian-Campanian; Maestrichtian; Danian-Thanetian." --

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 educational modules, allowing for virtual visits to rich geological times. Eras and events that are discussed include, but are not limited to, the much varied Quaternary environments, the evolution of plants and animals during the Cenozoic, the rise of angiosperms, vertebrate evolution and ecosystems in the Mesozoic, the Permian mass extinction, the late Paleozoic glaciation, and the origin of the first trees and land plants in the Devonian-Ordovician. With state-of-the art expert scientific instruction on these topics and up-to-date and scientifically accurate illustrations, this book can serve as an international course for students, teachers, and other interested individuals.
