The book investigates the geological and paleontological shifts in Kings County, Nova Scotia, following the Triassic period. It examines the fossil record and geological strata to reconstruct the environmental and biological changes that occurred in this specific region over millions of years. The work likely draws upon field research and existing geological surveys to present its findings on post-Triassic life and landscapes.

This work is likely a specialized academic text focusing on regional geological history. Its value would be to researchers and students of paleontology and Nova Scotian geology, providing detailed data and analysis specific to the post-Triassic period in Kings County. The authority perspective would stem from its scientific rigor and contribution to the understanding of Earth's history in a particular locale.
