Description

This rare Rhexoxylon fossilised petrified wood specimen is a beautifully preserved slice of Triassic-era plant material, weighing 2.066 kilos and measuring approximately 20cm wide x 18cm high x 5cm deep. Rhexoxylon is a genus of fossilized seed fern (corystosperm) wood from the Upper Triassic period, around 200 million years old, often found in regions like Zimbabwe (Gokwe) or Madagascar. The petrified wood has undergone mineralization, replacing the original organic structure with silica-rich agate or chalcedony, resulting in a durable, polished piece with subtle colour variations and patterns.

The specimen showcases the characteristic woody texture and growth rings of Rhexoxylon, with potential green hues from chromium impurities or grey/orange/pink shades typical of these fossils. It’s an excellent example for display, highlighting the natural history of ancient seed ferns that once grew in vine-like forms with woody trunks.
