Eparietites sp. - Lower Jurassic - UK

This Eparietites from Scunthorpe features a predominantly white appearance due to calcite mineralization, with golden-colored suture lines. The original shell, mineralized with calcite, often shows shades of gray-green or dark green, and polishing enhances the ammonite’s color depth and visual richness.

Typically, early cephalopod ammonites have relatively simple suture lines, with more complex patterns developing later in the Cretaceous. However, this Jurassic specimen already displays intricate and elaborate sutures.
