HUGE Dinosaur fossil gembone from Utah agate gem bone agatized 11.9 lbs For Sale

HUGE agatized dinosaur gem bone unearthed from the Morrison Formation in Utah. Age is Late Jurassic (148-155 million years old).

Polished on one side to show inner bone detail while preserving the natural look as it was found across the rest of the specimen. Weight is 11.9 lbs (190.4 oz). 

Agatized dinosaur bone is a rare form of fossilized dinosaur bone where the original fossilized bone has been re-mineralized, or replaced, with gem-forming silica-based compounds, such as agate, jasper, chalcedony, or opal.

Outstanding display piece for your collection! Most agatized dinosaur bones are much smaller (an inch or so being common) or are sold as thin slices - it is extremely rare to have a large piece of bone of this size and pieces like this don\'t come up often, and won\'t last long!
