4" Polished, Agatized Dinosaur Bone (Gembone) Section

This is a vibrantly colored, polished section of Late Jurassic aged dinosaur bone from Utah. One side has been polished a mirror finish which allows for the beautiful internal cell structure to be easily seen. This is a section of a limb bone. It comes with an acrylic display stand.

Agatized dinosaur bone is a rare form of fossilized dinosaur bone where the original fossilized bone has been re-mineralized (replaced) with silica based compounds (agate, jasper, chalcedony, or opal). The agatized bone is either found as fragments on the surface from bones or partial bones that have long since been destroyed by exposure to the elements, or as broken and tumbled chunks in event layers of the quarry. It could have come from any of a number of dinosaurs from this formation, though sometimes based on cell size and outer appearance the type can be narrowed down.
