Though it encompasses the majority of the Earth's history, much about Precambrian time still remains unknown to us. With its climate extremes and unstable surfaces, Precambrian Earth hardly resembled the planet we see today. Yet for all its differences, it made the existence of future generations possible. This volume helps unlock the mysteries of prehistory by considering available geologic evidence while providing a deep dive into the finesses of geochronology.
