1 in stock


Pictures do not do these clams justice.

Don’t know which side I like better. One has a broken open clam with numerous spectacular calcite crystals while the other side has a clam, barnacle and Chesapecten scallop.

This is a MERCENARIA permagna fossil clam with spectacular calcite crystals. The crystals are phosphorescent. They glow for some time after you remove light
Fossilized pelecypod from a famous area in Florida.
Pleistocene Period approx. 2 Million Years Old

This is a beautiful fossil clam with stunning amber colored internal calcite crystals surround by matrix. This specimen is from the famous “Ruck’s Pit” in the town of Fort Drum in Okeechobee County, Central Florida. It is found within the quarry in matrix of lithified coquina.

The crystals grew in the hollow cavities after the soft tissues of the clams in the deposit decomposed while the clam was still under water. The calcite was dissolved in the water and as it percolated through the sediment it was deposited in the cavity creating the amber colored crystals.
The site was discovered while excavating limestone aggregate. The quarry was closed in 2008.
Fossils from this classic site are exceedingly rare and hard to find. material that is coming from the area is substandard to the classic clams coming out in the past.

This piece is an irregular 6 1/2 inches by 5 inches. It has numerous nice and well formed calcite crystals.

The fossil pictured is the one you will receive.
