This collection comprises four natural geological specimens. It features two spiral-form ammonite fossils, one embedded in a dark, coarser rock matrix and another in a lighter grey, finer matrix. Also included is a rectangular piece of fossilized colonial coral, light tan in color, exhibiting numerous distinct, star-like polyp patterns. The collection is completed by an irregularly shaped, dark grey stone with a prominent, naturally formed or modified circular perforation. All pieces display characteristics consistent with natural geological formation and fossilization processes.
