Two Fossil Clams (Mercenaria) - Ruck's Pit, FL

This is a pair 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 though they are only visible on the smaller clam. These crystals are highly fluorescent under both short and long-wave UV. The fossils are Early Pleistocene in age, or approximately 2 million years old.

The base of the rock has been cut flat so that it stands up nicely without the need for a display stand.

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.
