Description
Every mineral is a story of chemistry, pressure, and patience. Eurypterids — ‘sea scorpions’ — were the apex predators of Silurian seas and freshwaters, some reaching 2.5 meters. This specimen, approximately 430 million years old, preserves the articulated appendages and paddle-like swimming legs of an arthropod lineage that ruled for 200 million years before dying in the Permian extinction. Their nearest living relatives are horseshoe crabs.
This specimen originates from Bertie Formation, New York, USA, one of the world’s most significant localities for this type of material. Collectors and scientists have drawn from this region for generations, and for good reason: the combination of geological conditions here produces specimens of exceptional quality and clarity.
Every specimen is unique. Photographs approximate the visual experience, but the real thing — its weight, its luster under a raking light, the way it catches the corner of your eye — can only be experienced directly.
