7.6" Polished Sauropod Limb Bone (Gembone) Slab - New Mexico
This is a very vibrant, 7.6" wide slab of an agatized sauropod dinosaur limb bone (gembone) from the Morrison Formation in New Mexico. It is cut flat on both sides and polished to a glossy finish on one.
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 glue stabilized fracture through this specimen. Comes with a 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.
