Natural *Douvilleiceras* Ammonite from Madagascar (Commonly known as "Ram's Horn" ammonite) An ancient Cretaceous-era marine ammonite specimen, fully agatized and translucent with a golden-yellow hue. It features an intact shell and a gracefully shaped aperture. The characteristic dendritic suture lines are clearly defined; the polished surface is smooth and lustrous, glowing with translucency when backlit—making it ideal for tactile handling and collecting. Dimensions: Approx. 7.4 cm Note: There is a minor repair on the ventral side. A natural prehistoric fossil formed over hundreds of millions of years; as a creation of nature, it inevitably bears subtle natural markings. The photos show the actual item; every spine and pattern is unique and irreproducible. Suitable for fossil enthusiasts, as a handheld piece for tactile enjoyment, or as a mineral specimen display.
