Peanut wood is a special fossilized stone. 120 million years ago, coniferous trees stood along the water in an area where Western Australia is now located. Pieces of wood regularly ended up in the water, from which they were transported into the ocean. This driftwood was noticed and attacked by the larva of shellfish.

Problem for ships

These larvae ate their way through the driftwood. this larva is known to us under the name' shipworm' centuries ago this larva was a big problem for our wooden ships. They could make hundreds of holes in a single sea voyage. The driftwood was also completely pierced to the point where the buoyancy was so low that the remaining piece of wood subsided to the bottom.

Start of petrification

Here the hole was filled by a light substance. Afterwards it was covered with several layers of mud and sediment up to the point where the fossilization process started. The remaining wood was eventually petrified in a brown color, while the drilled holes remained light in color. This explains the name 'Peanut wood'.
