5.4" Fossil Clam With Fluorescent Calcite Crystals - Ruck's Pit, FL

Fossil Clam With Fluorescent Calcite Crystals - Ruck's Pit, FL #175655

This is a 5.4" wide, fossil clam (Mercenaria permagna) from the the famous Ruck's Pit quarry in Florida. The interior of the clam is filled with golden-yellow calcite crystals which are highly fluorescent. These fossils are Early Pleistocene in age, or approximately 2 million years old.

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