Crystalized Clam (OK4)
Crystalized fossil clams like this are exceptionally rare. These clams lived in a shallow sea that covered most of Florida 2 million years ago. A sudden storm event buried the clams, trapping cavities inside. When the shells began to dissolve, it provided the material necessary to grow calcite crystals in the open spaces. These unusual fossils are known from only one site, an old quarry near Lake Okeechobee. The quarry played out and flooded in 2007. We excavated this in 2023. An attractive and informative display card accompanies the specimen.
Notes specific to this specimen: Double hollow with great dogtooth calcite crystals replacing this clamshell. In matrix.

Dinosaur Bones (D4)
Notes specific to this specimen: This is a distal manus digit (“finger”) bone of Edmontosaurus. In vertebrates, the ends of the front appendages are called the “manus” (aka hand) while the back are called the “pes” (aka foot). The fine detail on the bone surface is remarkably well preserved. This piece has a small amount of reconstruction as shown in the dark paleoclay area.

Iron Stromatolites (ME5)
Notes specific to this specimen: Beautiful deep red agatization in these colonies attest to the classic origin of this specimen as being from the old Mary Ellen Mine in Biwabik, Minnesota, the type locality for the Biwabik Iron Formation. Notice the off-set angle of the growth pattern in this piece. This is attributed to constant water currents in the area where these colonies were growing.

Iron Stromatolites (ME3)
Notes specific to this specimen: Rare white colonies with dark banded growth rings. Some have branchings. Specimen found in 1990s at the old Mary Ellen Mine in Biwabik, Minnesota, the type locality for the Biwabik Iron Formation. Notice the silvery spots of concentrated iron between the colonies.

Volcanic Bomb (EB6)
Notes specific to this specimen: Complex plump fusiform bomb with smooth aerodynamic striations. Apparently ran into another bomb during flight and part of that bomb is still attached but is not complete. Natural breaks reveal chalcedony interior which fluoresces a vibrant green. Unusual.

Crystalized fossil clams like this are exceptionally rare. These clams lived in a shallow sea that covered most of Florida 2 million years ago.

Agatized Algae (AA4)
Notes specific to this specimen: A rare, complete nodule. This specimen is a round, deflated sphere with nice bubbly agate skin all over it. One side is concave, the other convex, indicating the orientation of the original colony in the sediments. Can you guess which way it was oriented? Answer – the convex side was up. As the sediments accumulated and the agal ball deteriorated, the top collapsed. The bottom, meanwhile, was supported by the sediments below allowing it to retain its original shape.
