The Emergence of Animals: The Cambrian Breakthrough
Mark A. S. McMenamin, Dianna L. Schulte McMenamin
The authors explore the late Precambrian and earliest Cambrian fossil record to explain the Cambrian phenomenon and discuss the possibility of a major turnover in marine ecology at the beginning of the Cambrian period or whether a new, improved type of animal appeared at this time. They support their often controversial conclusions with photos and illustrations of fossils, some never before published.
