Rare, 7.2" Petrified Seed Fern (Rhexoxylon?) Round - Madagascar
This is something you certainly don't see everyday, it's a round of petrified seed fern (Rhexoxylon) from Madagascar. Nearly all 99%+ of the petrified wood from Ambilobe, Madagascar is Araucaria and the polisher I work with says this slab came from only the second log of Rhexoxylon he's seen from the area. The round is 7.2" wide and polished to a mirror like finish on one side. Comes with a display stand.
