Pre-Cambrian Fossiliferous Formations is a scientific book written by Charles Doolittle Walcott and published in 1899. The book is a comprehensive study of the fossiliferous formations that were present in the Pre-Cambrian era, which is the earliest geological time period in Earth's history. Walcott, who was a renowned paleontologist and geologist, provides a detailed account of the different types of fossils found in the Pre-Cambrian rocks, including algae, bacteria, and other primitive organisms. He also discusses the various geological processes that contributed to the formation of these rocks, such as volcanic activity and sedimentation.The book is divided into several chapters, each of which focuses on a specific aspect of the Pre-Cambrian fossil record. Walcott provides detailed descriptions of the different types of fossils found in each formation, along with illustrations and photographs to help readers visualize what these ancient organisms looked like.In addition to its scientific contributions, Pre-Cambrian Fossiliferous Formations is also notable for its historical significance. At the time of its publication, the idea that life existed in the Pre-Cambrian era was a controversial one, and Walcott's work helped to establish the existence of these ancient life forms.Overall, Pre-Cambrian Fossiliferous Formations is an important scientific text that provides a wealth of information about the earliest forms of life on Earth. It is a must-read for anyone interested in the history of our planet and the evolution of life.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
