Excerpt from Contribution to the Fossil Flora of Florissant, Colorado The plants found at Florissant belong to the Tertiary period and to that division known as the Green River group. The shales in which the fossil plants occur are composed of vol canio sand and ash, and are mostly drab, light-gray or light brown in color. Some of the plants have been beautifully preserved.

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

The Florissant formation's fossil beds and petrified forest are interesting in themselves but also shed light on questions of paleoecology, macroevolution, and taphonomy (the study of the process of fossilization). Meyer (National Park Service. Florissant Fossil Beds National Monument, Colorado) and Smith (U. of Colorado Museum of Natural History--Paleontology/geological sciences, UC, Boulder) introduce 11 papers examining Florissant fossil flora, fauna, mineralogy and geochemistry through different periods and via a model of the role of microbial mats in its preservation. An integrated database/Web site to further related research is also discussed. The monograph is well-illustrated with geologic maps and images of historical figures in the field and specimens, but is not indexed.

This comprehensive systematic revision of the Bridge Creek flora is based on large collections of megafossil specimens from the John Day and Crooked River basins. The flora was found to be more diverse than previously recognized, with at least 125 species. At least 11 genera are extinct, but the majority are extant members of deciduous forests. The flora was derived from a variety of sources and represents a classic example of the broadleaved deciduous forests that became widespread at mid-latitudes following the Eocene-Oligocene climatic cooling.

DIVPerhaps the world’s most distinctive tree, ginkgo has remained stubbornly unchanged for more than two hundred million years. A living link to the age of dinosaurs, it survived the great ice ages as a relic in China, but it earned its reprieve when people first found it useful about a thousand years ago. Today ginkgo is beloved for the elegance of its leaves, prized for its edible nuts, and revered for its longevity. This engaging book tells the full and fascinating story of a tree that people saved from extinction—a story that offers hope for other botanical biographies that are still being written./divDIV /divDIVInspired by the historic ginkgo that has thrived in London’s Kew Gardens since the 1760s, renowned botanist Peter Crane explores the evolutionary history of the species from its mysterious origin through its proliferation, drastic decline, and ultimate resurgence. Crane also highlights the cultural and social significance of the ginkgo: its medicinal and nutritional uses, its power as a source of artistic and religious inspiration, and its importance as one of the world’s most popular street trees. Readers of this extraordinarily interesting book will be drawn to the nearest ginkgo, where they can experience firsthand the timeless beauty of the oldest tree on Earth./div

Colorado Flora: Western Slope describes the remarkable flora of the state, distinctive in its altitudinal range, numerous microhabitats, and ancient and rare plants. Together with Colorado Flora: Eastern Slope, Fourth Edition, these volumes are designed to educate local amateurs and professionals in the recognition of vascular plant species and encourage informed stewardship of our biological heritage. These thoroughly revised and updated editions reflect current taxonomic knowledge. The authors describe botanical features of this unparalleled biohistorical region and its mountain ranges, basins, and plains and discuss plant geography, giving detailed notes on habitat, ecology, and range. The keys contain interesting anecdotes and introductions for each plant family. The book is rounded out with historical background of botanical work in the state, suggested readings, glossary, index to scientific and common names, references, and hundreds of illustrations. The books also contain a new contribution from Donald R. Farrar and Steve J. Popovich on moonworts. The fourth editions of Colorado Flora: Eastern Slope and Colorado Flora: Western Slope are ideal for both student and scientist and essential for readers interested in Colorado's plant life.
