7.5" Cluster of Fossil Clams With Fluorescent Calcite - Ruck's Pit, FL

Cluster of Fossil Clams With Fluorescent Calcite - Ruck's Pit, FL #242884

This is a 7.5" wide cluster of fossil clams (Mercenaria permagna) from the the famous Ruck's Pit quarry in Florida. The interior of the clam are filled with golden-yellow calcite crystals that are are highly fluorescent under both short and long-wave UV. There are clam fossils visible on both sides of the rock with the largest being 4.9" wide. It comes with an acrylic display stand.

Ruck's Pit was a small cement quarry that produced some amazing crystal lined fossils during the 2000s. Around 2006, the quarry was shut down and filled in with water. While some material can still be found in tailing piles from the quarry, high quality specimens of these remarkable crystal-filled fossils are becoming hard to acquire.
