The Precambrian-Cambrian Boundary (Oxford Monographs on Geology and Geophysics)

Events across the Precambrian-Cambrian boundary brought about the most dramatic geological change in Earth's history: the appearance of invertebrates, including animals with hard parts, that began the Phanerozoic fossil record. This book provides an up-to-date review of the "Precambrian-Cambrian boundary problem" as seen by a group of experts active in this controversial area of research. For more than a decade, international groups have been unearthing new information about the sequence of events during this period, centered around the question of where to fix the actual boundary point. Using a chronological framework, the book gathers together information essential to the understanding of the evolutionary extinctions and events that brought the Precambrian period to an end.Cowie, J.
