Ammonites: The Spiral Shells That Ruled the Seas | 98 Facts to Fall Asleep To

Imagine a creature with a shell so vast it could span over six feet, a spiral behemoth navigating ancient oceans while dinosaurs roamed the land. This 98-fact sleep documentary delves into the fascinating world of Ammonites: The Spiral Shells That Ruled the Seas. Discover everything from their Devonian origins to their Cretaceous demise, exploring their unique phragmocone and siphuncle for buoyancy, their jet propulsion, and their predatory beak-like jaws. We examine the intricate suture lines paleontologists use to identify species, the diversity of their shell coiling, including uncoiled heteromorphs, and their relationship to modern cephalopods like octopuses and squid. Learn about the massive Parapuzosia seppenradensis, the fossilization process from aragonite to pyritization, and the precious ammolite found in Canada.
