  • 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.

  • Agatized Algae (AA4)

    Notes specific to this specimen: A complete nodule featuring bullseye and bubblegum agate with a rich variety of textures and colors. The cracks are relics left over from when the original algal ball collapsed in on itself 165 million years ago, making this a very dynamic piece.

  • Agatized Algae (AA8)

    Notes specific to this specimen: Strange shape with a variety of colors. This is one of the more unusual specimens we’ve seen – it contains relic cracks from the collapse of the original structure and a variety of textures and colors. Which end was up? We cannot tell on this one! Zoom in on the bubbly side – it’s awesome!

  • Agatized Coral (AC10)

    These unique fossils are preserved corals that lived in large reef systems in Florida and Georgia about 34 million years ago. After the corals died, they were buried in deep sediments where the original corallite structures began to erode away. In some cases, this resulted in hollow cavities that were then coated in translucent agate, forming carnelian geodes. In others, the agate replaced the solids and retained images of the coral structures. We are the oldest and most experienced source for these unique fossils. Our teams have been SCUBA diving for these corals since the mid 1970s.

     

    NOTE: Unusual piece with preserved coral structures. Cut and polished face. An attractive and informative display card accompanies the specimen.

     

    SIZE: 6″x 5″x 5″

  • Agatized Coral (AC2)

    Notes specific to this specimen: This is an exceptional and exquisite carnelian agate pair with rare fortified agatized cavities and preserved microscopic internal structures. This cut and polished pair is mounted on a pleasing piece of Suwanee Limestone – which is the matrix material these specimens originated from. No other preparator mounts these specimens on their native matrix. Honestly, most people don’t even know how they formed, much less know the association with Suwanee Limestone! You can see how translucent the hollows are – the carnelian agate just glows! Zoom in and look at the lighter colored sections below the hollow and you’ll see that it’s actually lace agate. We’ve never seen this before This is a one-of-a-kind beautiful pair!

  • Crystal Clam Wall (OKW7)

    Notes specific to this specimen: One of a kind unbelievable specimen! This was dug out in 2023 as several pieces that have been reconstructed into a continuous matrix piece with breathtaking beauty. This is the largest crystal clam matrix specimen in the world. There are over 50 crystalized fossil clams, two crystalized conchs, along with scallops, olive shells, welks, corals and hundreds of other fossil shells in this magnificent museum piece.

     

    HOW THEY FORMED
    The area around Lake Okeechobee, Florida was a shallow sea about 2 million years ago. These clams lived in the sandy mud near the shoreline at the time. Sudden storm events – such as hurricanes and tropical storms – periodically buried the area under deep sediments, trapping the clams and other shellfish that lived there. As their bodies decayed, the process left behind cavities in the shells. With the heat and pressure that accompanied the pile-up of sediments, the original shell material (aragonite) became unstable and began to dissolve away. As it happened this provided the elements necessary to grow pure calcite crystals in the open spaces within some of the shells. It has a sturdy backing of plywood with an aluminum frame allowing this piece to be hung either vertically or horizontally. It’s currently on display at 1889 Studios, in the Uptown Rapid (formerly Rushmore Mall) complex in Rapid City, SD. Contact us for shipping options.
