Large Dino Bone/Gembone Cab * 41.04 x 25.04 x 7.33mm * agatized dinosaur bone

This awesome Dino Bone cab has very well defined cells with crisp outlines. The contrast between the webbing and the cells is great. This has a medium dome front that rolls over to the curved sides and then to a flat back with angled edges. The back has a satin finish while the front is polished. It measures 41.04 x 25.04 x 7.33mm. Agatized dinosaur bone is a rare form of fossilized dinosaur bone where the original fossilized bone has been re-mineralized, or replaced, with silica-based compounds such as agate, jasper, chalcedony, or even opal. It can be traced back to dinosaurs that roamed the earth during the late Jurassic Age around 150 million years ago. Dino bone possesses a rather wide range of possible color. Browns and blacks are most common, but reds, oranges, greens, and blues are all possible. Yellow is often considered a premium color and can be hard to find. Elements such as chromium, iron oxide and manganese all do their part to provide the unusual colors possible within dino bone.
