Its general appearance is a light beige hue with darker shades in the depressions, typical of ammonites preserved in calcareous matrices. The coiling is complete, and the center of the fossil reveals the siphuncle, characteristic of this group of fossil cephalopods.\u003c\/p\u003e\n\n\u003cp\u003eThe outer surface shows fine, regular striations, indicating quality fossilization. Some areas have a slightly more granular texture, due to natural alteration of the stone over time. The visible end of the spiral appears partially eroded, revealing the internal structure of the fossil. The overall piece has a matte patina, with no artificial polishing marks.\u003c\/p\u003e\n\n\u003cp\u003eThe dominant color is a stony beige, enhanced by pale gray reflections in shaded areas. The relief accentuates the typical ammonite pattern, with an alternation of regular ridges and furrows. No major chips are visible on the photographed side, but the structure shows natural irregularities characteristic of this type of piece from the Jurassic period.\u003c\/p\u003e\n\n\u003cp\u003eThe object is displayed in front of a wooden box with gold decoration, which highlights the spiral shape and mineral appearance of the ammonite. No stand or support is visible; the piece simply rests on the background, allowing its complete silhouette and relief to be appreciated.\u003c\/p\u003e\n\n\u003cp\u003eThe style of fossilization and morphology indicate a typical provenance for Jurassic ammonites, a period mentioned in the keywords. This type of fossil is sought after for decoration, natural history study, or collection of natural minerals. The piece offered here, with its well-preserved spiral and distinctive details, is a representative example of this fossil family.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eCondition\u003c\/b\u003e  \nUsed item, sold as is.

Their spiral shells, divided into chambers, allowed them to regulate their buoyancy in Jurassic seas. These fossils are used as stratigraphic markers to date the geological layers in which they are found.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eAFW Reassurance\u003c\/b\u003e  \nCareful packaging and fast shipping.
