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

The work first outlines the principles of palaeontology and sedimentary geology, explaining fossil types, processes of fossilization, rock formation, and stratigraphic methods used to determine the age and origin of strata. It discusses gaps in the geological record, unconformities, and how fossils indicate past environments, climate change, and crustal movements, as well as patterns of extinction and faunal succession. The second part offers a chronological survey of fossil-bearing formations, describing lithology, geographic distribution, and characteristic life-forms for successive periods from the oldest pre-Cambrian deposits through Cambrian and Silurian strata, with zoological descriptions presented in accessible, non-technical language and illustrated support.
