This ia highly unusual specimen! The "matrix, is a pyrite cast after, I think, calcite. It shows the form of a calcite crystal inside and under. On the outer side of the cast are complex crystals of pyrite poking out here and there. Interestingly, there is one pyrite on the inside of the cast, which indicates that the coherent pyrite crystals formed after the fine-grained cast. Wonderful!
