6.35" Polished Dinosaur Vertebra Section (Gembone) - New Mexico
This is a very vibrant, 6.35" wide section of an agatized dinosaur vertebra (gembone) from the Morrison Formation in New Mexico. It is cut flat and polished to a glossy finish on one side while the opposite side has been left in its rough state.
Nearly all of the gembone you see in from either Colorado or Utah, but this material we just acquired is from New Mexico. There is a repaired crack through the specimen. Comes with an acrylic display stand.

About Gembone
Dinosaur gembone (agatized dinosaur bone) forms when the porous structure of dinosaur bone is replaced by silica-rich minerals like agate, chalcedony, or jasper. This preserves the bone’s internal cell patterns, creating striking, web-like textures visible when polished.
Most gembone comes from the Late Jurassic Morrison Formation of Utah and Colorado and can display vivid reds, browns, purples, blacks, or blues—depending on the minerals involved. Highly valued by collectors, jewelers, and lapidary artists, each piece is unique, offering a beautiful and tangible link to prehistoric life.
