This striking specimen is a beautifully preserved ammonite fossil from the genus Dowilliceras, dating back to the Cretaceous period (approx. 100–93 million years ago). Discovered in the rich fossil beds of Madagascar, this ammonite displays the classic ribbed and coiled shell structure characteristic of the species, with strong, well-defined ridges spiraling outward from the center. The fossil exhibits a natural blend of earthy hues, including soft grays, creams, and hints of greenish tones, highlighting the mineralization process that occurred over millions of years. Its intricate chambered whorls and ribbed ornamentation make it not only a scientifically valuable specimen but also a visually stunning piece. Ammonites like this were marine mollusks, closely related to modern squids and octopuses, and their fossils serve as important index fossils, helping geologists date the layers of rock in which they are found.
