Ammonite Fossil Pair

A single ammonite fossil, the coiled shell of a squid-like cephalopod that swam Jurassic seas roughly 150 million years ago, sawn straight through its spiral and polished into two mirrored halves that still fit back together along the cut. Each half reveals the chambered interior the animal built as it grew, walling off the outgrown sections of its own shell one by one, a structure invisible from the outside of an unopened specimen. Ammonites were long mistaken for coiled snakes turned to stone, and were sold in English markets for centuries as "snakestones," sometimes carved with a crude snake's head to complete the illusion. Folklore across Europe made them charms against serpents and against ill luck more generally, an association that outlived the geological explanation of what the fossils actually were by hundreds of years. Display the pair together, the two halves set side by side or apart, or keep them as a single specimen split between two rooms. No cleaning or maintenance is needed beyond keeping the polished faces out of frequent handling, since skin oil dulls the shine over time. A matched pair sawn from a single fossil, 150 to 250 grams total, sourced from Madagascar. Sold as a curiosity and a specimen of natural history — no medical or scientific claims are made.
