Pyritized ammonite 3.4g 17.9mm

A whole pyritized ammonite with warm bronze-gold colouring and clearly defined ribbing visible on the inner whorls, transitioning to a rougher pyrite surface texture on the outer section. The combination of preserved ribbing on the inner spiral and raw mineral texture on the outer gives this specimen a varied, layered character.

Inner whorl ribbing visible on a pyritized ammonite indicates the original shell morphology is well-preserved beneath the pyrite replacement. Natural pyritized ammonite from Aveyron, France, Jurassic. Natural pyrite ammonite fossil, gold metallic fossil, French Jurassic collector piece, fossil mineral specimen.
