Teredo wood is petrified wood marked by tunnel-like holes left by ancient shipworms. Mineralization preserved the wood and often filled those holes with chalcedony, giving it a distinctive, almost Swiss-cheese look.
What makes teredo wood unique is the fact that it has “holes” across its surface. This gives the wood a Swiss-cheese-like appearance, although the holes have long been filled in as the fossil became mineralized.
Sometimes the holes are lined with sparkling quartz or calcium carbonate crystals, creating a natural druzy inside the old shipworm tunnels.
