Calcite in fossilized mollusc (Pleistocene Epoch)

Item Description

This fascinating LARGE CABINET specimen was formed when gemmy calcite crystals grew in the natural pockets formed by buried fossil clamshells. The interior of the two shells now contain fine, gemmy, golden crystals. The large, nearly completely exposed mollusc is 10.0 cm Not many fine collector specimens come from Florida, of course! Very few of these specimens are on matrix, FEWER still have the size and double-barreled bonus of two shells encased in matrix. The matrix (as on this specimen) does add an attractive element and does increase the value. This large piece presents very well, with the two molluscs set in the matrix at opposing angles. This is Pleistocene Epoch (1.8 MY - 10,000 years BP) Mercenaria species.
