The larger whelk is 3.8" tall and the total size of the matrix is 5x4x3 inches. Supposedly the calcite crystals from this location fluoresce under UV light.

It comes from "Ruck's Pit" in Florida. Ruck's Pit was a small cement quarry, which for several years in the early 2000's produced some amazing crystal filled fossils. The quarry has been long shut down and filled in with water for several years. Because of this it's difficult to acquire these remarkable crystal filled fossil shells, particularly ones of high quality such as this.

Welk's were predatory sea snails that fed mainly on bivalves.
