Description

    AUSTRALIAN PETRIFIED WOOD
    Pentoxylon
    Jurassic, Miles Formation
    Queensland, Australia

    Australia may not be the first locality that comes to mind for Petrified Wood. Pentoxylon is a generic term for many types of extinct Jurassic seed ferns from the Injun Creek Formation in Queensland. Their unique characteristic is that each segment has its own center and the number of growth rings in each center are the same! Under magnification, there are actually small, hair-like growths that can be seen between each segment. This particular Pentoxylon has from five to eight segments. Scientific work is currently being performed on these rare specimens, which should result in the description of a new species. This specimen has a unique "bottle" shape with a well-polished surface that exhibits a colorful "star" pattern.
    Overall Measurements: 9 x 5.25 x 0.34 inches (22.86 x 13.34 x 0.86 cm)
    Offered at no reserve.
