Elk Creek Calcite with Inoceramus Fossil (Perry Seaway)
This stunning Elk Creek piece pairs golden calcite crystals with a beautifully preserved Inoceramus fossil—a large bivalve mollusk from the ancient Perry Seaway. The fossil shell rests freely atop the calcite, making this a dynamic and interactive specimen that bridges mineral beauty and deep-time history. A collector’s treasure from South Dakota’s Pierre Shale Formation.
