Unusual specimen of Permian aged fossilliferous rock which has been Quartz replaced (silicified), the internal mould of the Grantonia Hobartensis Brachiopod shell has been coated with fine micro Quartz crystals from a small find near Avoca, eastern Tasmania. Some fragmentary Corals are also evident in the matrix. It is difficult to see the micro Quartz xtls in a still image so I have filmed it on a turntable so you can see the xtls sparkle. Specimen measures 57x41x26mm. $20 including postage within Australia, Payment by Paypal only please.
