Paleosmunda Petrified Wood Stone Sphere Marble
This is small but lovely and very RARE Petrified Wood sphere is just 1.25 inch or 30 mm in diameter.
Paleosmunda is a primitive member of the Osmundoidae from the Permian Period (approximately 290 million years old) found in Central Queensland, Australia.
It is a fern, species: Paleosmunda williansoni.
From the Paleozoic Era, this gemstone is the fossilized stone of Osmunda fern leaves and stems. The stone formed when a fern died and was buried by sediments. Minerals in the groundwater then permeated the fern, replacing the original organic matter and turning it to stone.
