Cerdito Prospect Rift Crystals (CP14)
Notes specific to this specimen: Cool combination of nice light smokey quartz crystals and deep amethyst crystals in the same vein. Nice healed fracturing evident on the edge. This piece has a cut-flat bottom so it stands up and displays very nicely. Take a look at the cut bottom and you’ll see the very graphic splitting of the matrix and the subsequent infilling with white quartz and citrine.

Crystalized Clam (OK6)
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: Great honey calcite crystals replacing multiple clam shells trapped in matrix. This piece has a sawn flat bottom so it stands up nicely on its own

Agatized Algae (AA2)
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.

Dinosaur Bones (D3)
Notes specific to this specimen: Commonly called the “hoof” of a hadrosaur – in this case Edmontosaurus – this is the end bone of a pes digit (toe). 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.

Cerdito Prospect Rift Crystals (CP13)
Notes specific to this specimen: Cool combination piece dominated by a cavity of nice light smokey quartz crystals encased in an amethyst vein. Note: One of the large crystals has a broken tip. But the rest is clean and gemmy. This piece has a cut-flat bottom so it stands up and displays very nicely. Take a look at the cut bottom and you’ll see the very graphic splitting of the matrix and the subsequent infilling with deeper smokey quartz.
