Australian Fossilised Peanut Wood and Sterling Silver Pendants
Peanut wood, a fossil, is found at Mooka creek, about 170 km east of Carnarvon in Western Australia. This is the same location where mookaite and brecciated mookaite occur.
Peanut wood is so called because of the white patches and channels, sometimes resembling peanuts.
The dark part of the stone still shows the markings of wood, mostly araucarias, ancient conifers that fell into a shallow sea and later petrified. The white markings were caused by the teredo worm, a mollusc, eating through bits of the timber. The empty channels in the timber then filled with the skeletal remains of microscopic creatures called radiolarians (amoeboid protozoa). These fillings over the years became a form of opalite and now show up as highly attractive designs in this fabulous stone.
