Paleosmunda Petrified Wood Polished Piece
This gorgeous Petrified Wood polished piece is more 3.5 inches by almost 2.75 inches and 1.5 inches thick.
It does not stand on its own.
As is common with this material it does have lots of natural surface pits and fractures, including 2 very prominent fractures on its main face (first and second picture).
Lovely and very rare 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.
