The Pleistocene of North America and its vertebrated animals from the states east of the Mississippi River and from the Canadian provinces east of longitude 95°

This listening experience offers a thorough, geography‑focused survey of the North American Pleistocene, concentrating on the lands east of the Mississippi River and the Canadian provinces east of the 95th meridian. The narrator walks you through the era’s geological framework, from early interglacials and glacial phases to the shifting coastlines and continental elevations that shaped habitats for a remarkable array of vertebrates.

Building on that foundation, the work catalogs the fossil record of whales, seals, ancient mammals and megafauna, detailing where mastodons, mammoths, camels, bison, tapirs, rhinoceroses and even solitary ice‑age wolves once roamed. Regional breakdowns reveal patterns of migration, adaptation and extinction, giving listeners a vivid picture of how climate and land bridges linked North America with distant continents during the Ice Age.
