Baja California's Coastal Landscapes Revealed

Excursions in Geologic Time and Climate Change

Markes E. Johnson

University of Arizona Press, 2021

Baja California is an improbably long and narrow peninsula. It thrusts out like a spear, parting the Mexican mainland from the Pacific Ocean. In his third installment on the Gulf of California’s coastal setting, expert geologist and guide Markes E. Johnson reveals a previously unexplored side to the region’s five-million-year story beyond the fossil coral reefs, clam banks, and prolific beds of coralline algae vividly described in his earlier books. Through a dozen new excursions, in Baja California’s Coastal Landscapes Revealed, Johnson returns to these yet wild shores to share his gradual recognition of another side to the region.

Johnson reveals a geologic history that is outside the temporal framework of a human lifetime and scored by violent storms. We see how hurricanes have shaped coastal landscapes all along the peninsula’s inner coast, a fascinating story only possible by disassembling the rocks that on first appraisal seem incomprehensible.

Looking closely, Johnson shows us how geology not only helps us look backward but also forward toward an uncertain future. The landscape Johnson describes may be apart from the rest of Mexico, but his expert eye reveals how it is influenced by the unfolding drama of Planet Earth’s global warming.

The Behavior of the Earth

Continental and Seafloor Mobility

Claude Allègre

Harvard University Press, 1988

Well over a century after Darwin gave biology its unifying theory of evolution, the earth sciences experienced a similar revolution and the theory of plate tectonics took hold. Plate tectonics posed the idea that the earth's crust is divided into a number of large, thin plates always in motion relative to one another. In The Behavior of the Earth, world-renowned earth scientist Claude Allègre sets forth the exciting events in this contemporary revolution from its first stirrings in the nineteenth-century and Alfred Wegener's original model of continental drift (1912) through the development of its full potential in modern plate-tectonic theory.

Few scientific theories have been so all-encompassing, and none has surpassed plate tectonics in explaining such a wide variety of geological phenomena, from the origins of mountain building to the formation of the ocean floor. As it integrated our knowledge of the earth's surface with the investigation of its interior, plate tectonics fused two previously autonomous strains of scientific inquiry. Continental mobility changed for all time our view of the earth from a static globe to an evolving, living planet, and allowed us to see that changes in the earth's surface are but exterior manifestations of a dynamic interplay of forces within the crust and the mantle.Allègre casts his lucid exposition of this scientific theory within the historical context of its struggle for acceptance. As he introduces us to the huge cast of personalities and researchers who contributed to the theory, he illuminates the complex role that the scientific community plays in the proliferation and acceptance of new ideas. Allègre is as insightful in discussing the human motivation for scientific endeavor as he is skillful in presenting the science that results from this effort. Richly illustrated and including a glossary, this book offers the reader rare access both to the central theory of plate tectonics and to the constellation of problems and possibilities that preoccupy earth scientists today.

Biostratigraphic and Geological Significance of Planktonic Foraminifera

Marcelle K. BouDagher-Fadel

University College London, 2015

The role of fossil planktonic foraminifera as markers for biostratigraphical zonation and correlation underpins most drilling of marine sedimentary sequences and is key to hydrocarbon exploration. The first - and only - book to synthesize the whole biostratigraphic and geological usefulness of planktonic foraminifera, Biostratigraphic and Geological Significance of Planktonic Foraminifera unifies existing biostratigraphic schemes and provides an improved correlation reflecting regional biogeographies. Renowned micropaleontologist Marcelle K. Boudagher-Fadel presents a comprehensive analysis of existing data on fossil planktonic foraminifera genera and their phylogenetic evolution in time and space.

The Bone Hunters

The Discovery Of Miocene Fossils In Gray, Tennessee

Harry L. Moore

University of Tennessee Press, 2004

In the spring and summer of 2000, geologists working for the Tennessee Department of Transportation made an extraordinary find as they examined soil at a routine road construction project: the digging at Gray, Tennessee, had uncovered a fossil site containing bones that would turn out to be at least five million years old. Harry Moore and his colleagues, along with researchers from the state and the University of Tennessee, were stunned as they unearthed the fossilized remains of tapirs, elephants, rhinoceroses, alligators, and other long-dead animals. What was at first thought to be an Ice Age site ten to twenty thousand years old proved to be much, much older.
The Bone Hunters recounts the fascinating details of a remarkable chance discovery. In his engaging firsthand account, Moore writes of the people behind the excavation of the site and how their efforts helped save valuable artifacts for ongoing study. Numerous photographs capture the excellent condition of fossils at Gray. Moore also describes the contours of what the ancient landscape may have looked like and details the governmental action that ultimately preserved this Tennessee treasure.

Harry Moore manages the Tennessee Department of Transportation’s Geotechnial Engineering office in Knoxville. His previous books are A Roadside Guide to the Geology of the Great Smoky Mountains National Park, A Geologic Trip Across Tennessee by Interstate 40, and Discovering October Roads: Fall Colors and Geology in Rural East Tennessee (co-written with Fred Brown).

Bursting the Limits of Time

The Reconstruction of Geohistory in the Age of Revolution

Martin J. S. Rudwick

University of Chicago Press, 2005

In 1650, Archbishop James Ussher of Armagh joined the long-running theological debate on the age of the earth by famously announcing that creation had occurred on October 23, 4004 B.C. Although widely challenged during the Enlightenment, this belief in a six-thousand-year-old planet was only laid to rest during a revolution of discovery in the late eighteenth and early nineteenth centuries. In this relatively brief period, geologists reconstructed the immensely long history of the earth-and the relatively recent arrival of human life. Highlighting a discovery that radically altered existing perceptions of a human's place in the universe as much as the theories of Copernicus, Darwin, and Freud did, Bursting the Limits of Time is a herculean effort by one of the world's foremost experts on the history of geology and paleontology to sketch this historicization of the natural world in the age of revolution.

Addressing this intellectual revolution for the first time, Rudwick examines the ideas and practices of earth scientists throughout the Western world to show how the story of what we now call "deep time" was pieced together. He explores who was responsible for the discovery of the earth's history, refutes the concept of a rift between science and religion in dating the earth, and details how the study of the history of the earth helped define a new branch of science called geology. Rooting his analysis in a detailed study of primary sources, Rudwick emphasizes the lasting importance of field- and museum-based research of the eighteenth and nineteenth centuries.

Bursting the Limits of Time, the culmination of more than three decades of research, is the first detailed account of this monumental phase in the history of science.
