{"product_id":"ammonite","title":"Ammonite Split Fossil - Authentic Ancient Cephalopod Specimen","description":"\u003cp\u003eAmmonites are an extinct group of cephalopods that entered the fossil record 400 million years ago and survived every mass extinction event until the very end - when the same asteroid impact that killed the non-avian dinosaurs finally brought their 400-million-year run to a close. This \u003cstrong\u003eauthentic ammonite split fossil\u003c\/strong\u003e is a real ammonite specimen that has been split to reveal the breathtaking internal chamber structure hidden beneath the shell. The small size presents that interior architecture in a compact, displayable format.\u003c\/p\u003e\n\n\u003ch2\u003e\u003cstrong\u003e400 Million Years of Spiral Perfection, Revealed\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eSplitting an ammonite exposes the septal walls between its internal chambers - the intricate, fractal-like suture lines that made these creatures the index fossils of choice for stratigraphers mapping the geological column for over a century. The small split ammonite shows those chambers with the immediacy of a cross-section: the Fibonacci spiral of the coiling, the sequence of air chambers that controlled buoyancy, and the siphuncle channel that ran through the entire shell. This real ancient cephalopod specimen display is presented in a glass-topped riker display case measuring 4 in x 3 in x 1 in with an informational card also serving as the certificate of authenticity.\u003c\/p\u003e\n\n\u003ch2\u003e\u003cstrong\u003eThe Authentic Ammonite Split Fossil for Collectors\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThis is not a cast.
