Agatized Dinosaur Bone Chunk (Polished)

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. This piece has excellent, cell structure and is higher quality than most being sold.

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 a private quarry in the Morrison Formation, near Dinosaur, 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 water tumbled chunks in certain event layers. 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.
