## About
Open your hand and a spiral sea lies in it. This ammonite swam Jurassic seas roughly 150 million years ago, and now it rests in two mirrored halves that still fit back together along the cut.Ammonites were squid-like cephalopods that built their coiled shells chamber by chamber, walling off each outgrown section as they grew. That hidden architecture is invisible from the outside of an unopened fossil; here the shell has been sawn straight through the spiral and polished, so each half shows the chambered interior in full.For centuries ammonites were mistaken for coiled snakes turned to stone and sold in English markets as snakestones, sometimes carved with a small snake's head to complete the illusion. Folklore across Europe made them charms against serpents and against ill luck in general, a belief that long outlived the geology.DetailsOne ammonite fossil, sawn and polished into a matched pairAge: roughly 150 million years (Jurassic)Origin: MadagascarWeight: 150 to 250 grams in totalHow to useDisplay the halves side by side, set them apart, or keep one in each of two rooms. They need no cleaning or care beyond sparing the polished faces from frequent handling, since skin oil dulls the shine over time. Sold as a curiosity and a specimen of natural history; no medical or scientific claims are made. A small piece of deep time for your shelf.
