I found these scale looking fossils yesterday out looking on the Milk River. Does anyone know what the might be? I also posted one of my larger dinosaur bones that seems to have some opal veins maybe? not sure. Anyone have an idea about these? The scale looking one on the left has marrow and is a thin bone, the one on the right just looks like it was flaked off something. Appreciate the help.
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
