Early Life: Evolution on the PreCambrian Earth, Second Edition offers an informative and compelling analysis of microbial evolution, often overlooked as the opening chapter of life's history. With this long-awaited new edition, Lynn Margulis and Michael Dolan integrate new discoveries from the past two decades, such as the enormous contribution of molecular biology, especially the accumulation of protein and DNA sequence information upon which the Woese three-domain system is based. Yet the prokaryotic-eukaryotic distinction remains the largest evolutionary discontinuity in life on Earth. Are the well-formed filaments found so recently in the Warrawoona Series of northwestern Australia really evidence of the oldest life on the planet?Do the fossils found in the great Gunflint Iron Formation of Ontario tell that bacteria were instrumental in the accumulation of the most important iron reserves in the world?These questions are not solved here, but they are raised for students, scientists, and general readers interested in the most basic evolution and its consequences. No special scientific background is required of the reader, only a lively interest.

Contents: Historical aspects of Precambrian tectonics and metallogeny; Archaean supracrustal belts; Proterozoic mobile belts; Protoplatforms and ancient platforms; Regions of protoactivisation; Regions of tectonomagnetic activisation and rifting; Marginal and sulture structures; Deep structure of the continental crust and ore formation; Conclusions; Selected references; Index.

Today, Michigan is home to many different animals and plants. Yet nearly 12,000 years ago it was home to very different kinds of animals and flora. Huge mastodons and mammoths roamed through southern Michigan. Whales, walruses, and giant rodents swam in the lakes, and shaggy musk oxen grazed in the woodlands. Now, 2000 years later, all but their fossils are gone. Ancient Life of the Great Lakes Basin provides a one-of-a- kind look at ancient life in the Great Lakes. Written for the layperson and for the professional with biological or geological interest in the Great Lakes region, the book describes most of the common fossils found in this region. Detailed illustrations help identify many of the fossilized organisms that can be found today. Among the most interesting illustrations presented in the book are Gijsbert van Frankenhuyzen's conceptions of what the fossilized creatures may have looked like when they were alive. In addition, color illustrations by van Frankenhuyzen depict spectacular scenes of ancient life in the Great Lakes area.The book begins with a brief review of biological and geological principles and then offers a framework for the study of the fossil record. Methods of collection, preservation and maintenance of fossils are also presented. Throughout the book, common fossils found today embedded in rocks and other solid matter are emphasized.  J. Alan Holman is Curator of Vertebrate Paleontology in the Michigan State University Museum, and Professor of Geological Sciences, Michigan State University.

Being a Canadian carries with it a tangible sense of living on the edge of a vast barren interior. Only named as such in 1883, the Canadian Shield is an empty immensity of lakes, bogs, rivers, forest and protruding ribs of hard Precambrian crystalline rock that covers more than half of the total land area of Canada. This book traces the geologic evolution of the Shield, its first tentative exploration by humans starting 11,000 years ago as the last great ice sheets withdrew, its changing economic fortunes as Europeans penetrated its remote rocky vastnesses for furs and metals, and its transformation in the twentieth century into a national icon to Canadians. Regarded as 'barren' and of no value, much of the Shield was given away in 1670 to a single London-based fur trading company, the Hudson Bay Company, who jealously guarded its northern domain until 1867. This two hundred year long monopoly created a virtual government over a huge piece of North America. Without the HBC, much of it would have passed into American hands and there would have been no 'Canadian' Shield or country called Canada. As a nation, we are indebted to hard rock.

An illustrated survey of the geological history of the state of Iowa, from the Precambrian through to the end of the Great Ice Age, written by Professor of Geology at the University of Northern Iowa.

Where else can that well-known phrase be better applied than to a study of the Finns in Sudbury? “Rock” defines the physical reality of the Sudbury setting: rugged hills, mines, farms and forests set in the Precambrian Shield. “Hard” defines the human setting: Finnish immigrants having to contend with the problems and stresses of relocating to a new culture, with livelihoods that required great endurance as well as a tolerance for hazardous conditions. Since 1883 Finnish immigrants in Sudbury, men and women alike, have striven to improve their lot through the options available to them. Despite great obstacles, the Finns never flagged in their unwavering fight for workers’ rights and the union movement. And as agricultural settlers, labour reformers, builders of churches, halls, saunas and athletic fields, Finns left an indelible imprint on the physical and human landscape. In the process they have played an integral part in the transformation of Sudbury from a small struggling rail town to its present role as regional capital of northwestern Ontario. This penetrating study of the cultural geography of the Finns in the Sudbury region provides an international, national and local framework for analysis ― a model for future studies of other cultural groups.

This valuable book provides information on fossils, fossil collecting, and price ranges for most specimens illustrated. The comprehensive text begins with the earliest fossil record of life from strata representative of "deep time," called the Precambrian by geologists. Foremost in this early record of life are stromatolites, structures formed by very primitive photosynthetic life forms. Attractive, color photographs illustrate this highly informative section of the book. Also discussed and illustrated are various problematic fossil-like objects found in very ancient rock strata and the different ways in which they have been interpreted. Paleontological puzzles, such as latest Precambrian vendozoans, are covered as well. Other chapters feature fossils of the Cambrian Period, when animal life became obvious. Fascinating color photographs show trilobites (prehistoric creatures second only to dinosaurs in popularity), plus other Cambrian fossils. Includes helpful glossary of terms.

In this issue of Plateau Magazine, Wayne Ranney delves deep into the geological history of the Verde Valley. "The Precambrian" The geological record of the Verde Valley begins with rocks formed in the Precambrian Era, a time period so vast and far removed from the present that even geologists experience difficulty comprehending the length of time that it represents. "The Early Paleozoic" Whereas the Precambrian rocks exposed at Jerome give evidence for a submarine volcanic setting, most of the Paleozoic rocks in the Verde Valley record a time of hot, desert environments. "The Late Paleozoic" Without a doubt, the most spectacular rocks within the Verde Valley are the red rocks exposed near Sedona that were deposited during the Pennsylvanian and Permian periods. "The Mesozoic" When the Kaibab seas finally retreated about 260 million years ago, there were other environments that may have left sediment on top of the Kaibab formation. But the following 35 million years of earth history have no record on the Colorado Plateau. "The Cenozoic" Although it seems that the most recent history should be the easiest to document, the Cenozoic throughout much of Arizona was a time of erosion, and rocks either were never deposited or were stripped away.

From the initial signs of life in the Precambrian period to the end of the Cambrian period about 488 million years ago, this volume explores the development of early life that culminated in one of the most extraordinary periods in the evolution of life on earth.
