Author: Herbert William MeyerPublisher: Geological Society of America
ISBN: 081372435X
Category : Science
Languages : en
Pages : 192
Book Description
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.
The Oligocene Haynes Creek Flora of Eastern Idaho
Author: Daniel I. AxelrodPublisher: Univ of California Press
ISBN: 9780520098244
Category : History
Languages : en
Pages : 164
Book Description
This flora of 70 species is dominated by deciduous trees, many with descendants in China. Precipitation was 890 mm, mean annual temperature 12.5°C, the annual range 10°C, and freezing rare. Elevation was about 1000 meters. Comparison with the Horse Prairie flora, 30 miles east and across the present continental divide, indicates that the divide was then low and discontinuous, with warmer climate to the east.
