North American Mesozoic and Cænozoic Geology and Palæontology: Or, an Abridged History of Our Knowledge of the Triassic, Jurassic, Cretaceous and Tertiary ... of This Continent (Classic Reprint)

Unlock the past of North American geology and paleontology through the clues of drift, terraces, and ancient lakes. This edition gathers early scientific observations on how continents wore down, how lakes rose and fell, and how fossils reveal a long, changing landscape. It contrasts competing theories and shows how researchers built a chronological picture of the Triassic to Tertiary eras across the continent.The text surveys terraces along the St. Lawrence and Great Lakes region, the spread of drift deposits, and the evidence for or against glacial events. It connects fossil finds, river valleys, and ancient shorelines to a broad timeline that stretches from the Carboniferous to the Tertiary, offering a window into the methods and debates of early geology and paleontology.- See how terraces and beaches mark ancient water levels and shifting coastlines- Learn about drift deposits, lacustrine (lake) clays, and fossil collections from different eras- Explore the arguments scientists used to interpret climate, ice ages, and landscape change- Discover how early researchers connected fossils with geological layers to build a continental historyIdeal for readers of classic geology and paleontology, and anyone curious about how scientists pieced together North America’s deep past.
