6.8" Polished Dinosaur Vertebrae (Gembone) - Colorado

This is a centrum of a dinosaur vertebrae which has been agatized. The partial vertebrae was cut, and polished to reveal the beautifully preserved internal cell structure. It was collected from our partners private quarry, East of Dinosaur, Colorado this past year.

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 and is collected from our partner private quarry. 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.
