This is a shell from Lightning Ridge, Australia. It had something on it. Is this periostracum? if so how was it preserved in 3D. All images but the first one were taken under a microscope. Thanks!

Hello All, I was hoping that someone could help me identify this bone? its from the mid-Cretaceous Griman Creek Formation of Lightning Ridge Australia I don't think its a yabby button or turtle shell, as the piece is not rounded like a yabby button and there is bone texture. the piece is bilaterally symmetrical and there appear to have joins or groves where the bone meets. The underside is not flat like I would expect for turtle shell... Looking forward to your replies Rod

Name: Opalised Pine Cone Age: 110 million years old Locality: Lightning Ridge, New South Wales, Australia Formation: Griman Creek Formation Length: 16mm long Notes: This is an opalised pine cone from Australia. It is quite a rare specimen and is a great addition to my opal fossils collection. This specimen was kindly given to me by my friend Shaun. Thanks mate! -

Name: Opalised Bivalve Shell Age: 110 million years old Locality: Lightning Ridge, New South Wales, Australia Formation: Griman Creek Formation Length: 25mm Notes: This is an opalised bivalve shell from Australia. Unlike the marine shells from Coober Pedy, the other hotspot for opalised fossils in Australia, the shells from Lightning Ridge are less common and come from a freshwater river environment. This one is open, and clearly shows the ridged pattern of the shell it once was. A nice addition to my opal fossil collection. -

Name: Opalised Belemnite Pipe Age: 120 million years old Locality: Coober Pedy, South Australia Length: 60mm long Notes: This is an opalised belemnite pipe from Australia. It originates from the Cretaceous marine deposits of Coober Pedy and is transparent when held up to a strong light. It is also quite a large example. -

Name: Opalised Dinosaur (Caudal?) Vertebra Age: 110 million years old Locality: Lightning Ridge, New South Wales, Australia Formation: Griman Creek Formation Length: 16mm end to end Notes: This is an opalised dinosaur vertebra from Australia. I originally bought it as an opalised 'reptile' vertebra but it's ID as being a dinosaur vertebra was confirmed by one of the leading experts on the opalised fossils of Lightning Ridge. It is likely a juvenile ornithopod or theropod vertebral centrum, missing the tall neural arch. It is semi-transparent when held up to a strong light and is an exceptionally rare specimen. So far it is the only vertebrate fossil in my opalised fossils collection but I hope I am able to acquire more soon. Specimens like this very rarely come up for sale as most of them end up in museum collections due to their rarity and scientific value
