6.7" Polished Dinosaur Bone (Gembone) Slab - Utah
This is a 6.7" wide piece of agatized dinosaur bone from the Morrison Formation of Utah. One side has been polished to a glossy finish which allows for the beautiful internal cell structure to be seen. Both the small cell structure and the fact the bone isn't hollow indicates this came from a non theropod dinosaur, most likely one of the large sauropods.
It comes with an acrylic display stand.

About Dinosaur Gembone
Dinosaur gembone, also known as agatized or fossilized dinosaur bone, is a rare and highly prized material formed when the porous structure of dinosaur bone is replaced by silica-rich minerals such as agate, chalcedony, or jasper over millions of years. This fossilization process preserves the intricate internal cell patterns of the original bone, which are often visible as vibrant, web-like structures under the polished surface.
Gembone is typically found in the Morrison Formation of the American West, especially in Utah and Colorado, where Late Jurassic dinosaur remains are common. The resulting stones can display a wide range of striking colors—including reds, browns, purples, blacks, and blues—depending on the specific minerals present during fossilization.
Highly sought after by collectors, lapidary artists, and jewelers, dinosaur gembone is both a geological wonder and a tangible connection to the prehistoric past. Each piece is completely unique, with its own natural patterning and coloration shaped by ancient time and mineral-rich waters.
