Dragon’s Vertebrae also known as Thunder Egg Vertebrae is the core at the centre of a thunder egg. This was sourced by the fossicker (known to this seller) in the 1970s from Mt Jerusalem, New South Wales, Australia.
Created within volcanic deposits, where silica-rich waters fill cavities, crystallizing over time into agate and chalcedony. The distinctive vertebrae-like shape of this specimen adds to its rarity and visual appeal, making it a highly sought-after piece that can stand on its own in your display cabinet.
