Summary: "Ammonites are extinct marine animals related to present day squid, octopi and chambered nautilus. They have been collected and prized for centuries, yet they often remain unidentified in many collections due to a lack of published information. Ammonites and the Other Cephalopods of the Pierre Seaway will change that. This work is written for general understanding and consolidates the latest cephalopod information available in technical journals. The book includes easily understood descriptions of over 90 species, 32 genera, and 13 families of cephalopods that lived for about 12 million years in the Pierre Seaway, which extended through the interior of North America connecting the Arctic Ocean with the Gulf of Mexico."
