above: FJD Aussie 17.  Museum Specimen Conifer/Shipworm wood. Windalia Radiolarite fm, Lower Cretaceous, Kennedy Ranges, Western Australia, Australia. Full round, contour polished on one end and otherwise all natural. First the wood sank into salt water, next it was invaded by tunneling mollusks (i.e. teredo), then it fossilized, and who knows what else happened before it returned close enough to the earth’s surface to be dug up by a tanned, muscular Aussie with a rock hammer or more likely a backhoe. The lighter colored rock is also part of the original tree and has growth rings throughout. Much interest. No glue – no filler. 10 by 11 cm mirror-polished face; 21 cm long; eleven pounds and ten ounces. $750

Overall pleasing mineralization and pattern. The quality of the mineralization is like fine China with no fractures. Super high end. Specimen round slice. 23 by 8 cm mirror-polished face; 1 cm thick; thirteen ounces.  $100
