Pyritized ammonite 5.82g 23.5mm

A large pyritized ammonite with warm gold-bronze tones and dramatic, well-spaced ribbing clearly visible on the lower whorls - the best rib definition of the large specimens, with strong relief and clear separation between ribs. The upper portion has a rougher, more degraded surface; the intact ribbed section is the standout feature.

The combination of large size and prominent well-preserved ribbing makes this a high-impact display fossil. The largest specimen in the Aveyron series at 23.5mm. Natural pyritized ammonite from Aveyron, France, Jurassic period. Large pyrite ammonite fossil, ribbed gold ammonite, Jurassic France, fossil display piece.
