The Ancient Life History of the Earth: A Comprehensive Outline of the Principles and Leading Facts of Palæontological Science

A scientific publication written in the late 19th century. This work provides a thorough exploration of paleontology, specifically focusing on the historical aspect of the science and its interconnectedness with geology. It aims to outline the important principles and factual evidence associated with ancient life forms that once inhabited the Earth, as understood through fossil records. The opening of the book introduces readers to the dual methodologies of paleontological study—the anatomical examination of fossils and their historical context in geological strata. Nicholson emphasizes the importance of understanding how ancient life evolved in relation to Earth's geological changes and how fossils serve as key indicators of historical life forms and environmental conditions. He outlines his intent to provide a comprehensive overview while ensuring accessibility for both geology and zoology students, as well as the general reader interested in the intricacies of Earth's life history.
