Giant Fossil Shark Tooth with Coral
Notes specific to this specimen: An incredible find! Beautiful huge megalodon shark tooth with soft coral attachment. This 5 1/2″ specimen was discovered in 2000 on the bottom of the ocean off North Carolina and has been kept as found. It was discovered by the greatest shark tooth hunter ever – the late, great, Vito Bertucci – aka “Megalodon Man”. Vito was from the East Coast and well known as the most active collector of giant shark teeth ever and the creator of the largest shark jaw ever assembled. He passed away in 2004 while diving for teeth in the Ogeechee River, Georgia. There is some stabilization in the root but nothing has been done to the tooth itself other than cleaning it. Care has been taken to conserve the piece intact. Even the purple color of the soft coral is preserved. We traded for this from a private collector.

Potomac Marble Sculpture
Notes specific to this specimen: You won’t find this on the market anywhere! Why? Because we are the only people who excavate and sculpt this beautiful and unusual historic material. Also called Capitol Marble, this Triassic conglomerate is featured as the columns in the US Capitol National Statuary Hall rotunda. They hold up the main Capitol Dome. Interestingly, the location of the quarry where this material was mined was lost for 200 years. But the old quarry site was finally found a few years ago. We visited the site which is along the C & O canal (near milepost 38) in 2024. It hosts the exact same rock we collect for carving at Point of Rocks, some 12 miles upstream where this piece is from. This freeform was sculpted by Jon in 2022 and has a flat bottom for easy display. It features a highly polished partial helix on the front and a contrasting natural back, showing how the rock is found in its rough state.
HOW IT FORMED
Paleozoic mountains that were being uplifted during the Triassic Period as North America and Africa were colliding. About 205 million years ago these rivers carried broken pieces of dolomite into a basin where they were buried. As the layers accumulated in depth, heat and pressure built up and eventually cemented everything together. Later the layers were pushed up and erosion removed the sediments above, exposing this unique rock in certain locations along the Potomac River.

Rainbow Stromatolite (RS1)
Notes specific to this specimen: This is one of the original discovery pieces, collected by us in August 2025. It is characteristic of all the variety of colors found in this site. We’ve never seen such a variety of colors of stromatolite from a single site. It reminded us of all the colors of Arizona petrified wood – known as “Rainbow Wood” – and this became the source for our naming this new discovery “Rainbow Stromatolite”.
