    This is a beautiful piece of Late Jurassic aged, agatized dinosaur bone where one face has been cut and polished to reveal the wonderful internal cell structure. The polishing allows for the beautiful internal cell structure to be easily seen.

    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).

    It comes from the Morrison formation of Colorado. 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.
