This book was released on 1995-01-01 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, nine florules from the Chloropagus Formation near Fernley, Nevada, are dated at 14.7-13.4 million years. The author finds that dominant mixed conifer forest and sclerophyll woodland species of the Sierra Nevada-Klamath region replaced exotic deciduous hardwoods in the two lowest sites. He concludes that this change reflects the loss of adequate summer rain as upwelling from a colder ocean resulted from spreading East Antarctic ice.

Download or read book A Miocene 10 12 Ma Evergreen Laurel Oak Forest from Carmel Valley California written by Daniel I. Axelrod and published by Univ of California Press. This book was released on 2000-06-12 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a study of the Miocene Carmel flora of California, an evergreen laurel–oak forest that grew in a mild temperate (mean annual temperature of 15 degrees C), frost-free climate, with annual precipitation of about 760 mm (30 in.). Collectively, the Carmel and other Miocene floras like the San Pablo and Temblor (broad-leafed deciduous trees, with few evergreen species), the Puente (evergreen oak forest with chaparral species), the Mint Canyon, Ricardo, and Tehachapi (numerous arid subtropical scrub associated with oak woodland and chaparral species) suggest they foreshadowed a similar distribution of the different California vegetation zones today.

Download or read book The Oligocene Haynes Creek Flora of Eastern Idaho written by Daniel I. Axelrod and published by Univ of California Press. This book was released on 1998-07-31 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1998-03-17 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Eocene (45 Ma) flora from Thunder Mountain caldera shows that montane conifer forest species from upper slopes descended to interfinger with mixed conifer-deciduous hardwood forest on the caldera floor then near 1700 m. Most species are allied to those in the western United States, but a few genera are in China. Precipitation was near 100 cm yearly, with most in summer.

Download or read book Tectonic Boundary Conditions for Climate Reconstructions written by Thomas J. Crowley and published by Oxford University Press, USA. This book was released on 1998 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, efforts to integrate solid earth geophysical studies and climate studies have progressed slowly, but this volume responds to the deficiency with an in-depth examination of climate modeling. Written by eminent figures from both disciplines, it focuses on the role of tectonic boundary conditions for paleoclimate reconstruction at the same time it presents background material on the impact of tectonic changes on climate and the uncertainties in tectonic boundary conditions.

This book was released on 2000-03-08 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The author describes forty-two fossil taxa recovered during a study of the San Timoteo Badlands that used magnetobiostratigraphy to develop a temporal framework for addressing the tectonic evolution of southern California over the last 6 million years. For the Pliocene, small mammals are an effective means of correlating a magnetostratigraphy to the Geomagnetic Polarity Time Scale when radioisotopic dates are unobtainable.

Download or read book The Bug Creek Problem and the Cretaceous Tertiary Transition at McGuire Creek Montana written by Donald L. Lofgren and published by Univ of California Press. This book was released on 1995-08-31 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bug Creek assemblages from Montana, transitional in composition between typical Cretaceous and Paleocene vertebrate faunas, are critical to K-T extinction debates because they have been used to support both gradual and catastrophic K-T extinction scenarios. Geological and palynological data from McGuire Creek indicate that Bug Creek assemblages are Paleocene and restricted to channel fills entrenched into older sediments, suggesting that the Cretaceous component of the assemblage was reworked. Thus, the author concludes, "Paleocene dinosaurs" are an illusion and the K-T survival rate of mammals is low because the presence of Cretaceous mammals in Bug Creek assemblages is also the result of reworking.

This book was released on 1999-03-25 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
