Red Agatized Dinosaur Bone Necklace

This is a stunning necklace made from 150 million year old, red, agatized dinosaur bone and handcrafted in Utah. The polished bone is 1.5" tall and the necklace is 20 inches around. The internal cell structure of the dinosaur bone can clearly be seen. Only high grade, gem quality bone was used in the pendants.

The bone may have come from any of the dinosaurs found in the Morrison Formation including Allosaurus, Apatosaurus, Brachiosaurus, Camarasaurus, Diplodocus, Stegosaurus, and Torvosaurus. It was collected this past summer from a private quarry near Dinosaur, CO. While the quarry has produced articulated specimens of several species of dinosaurs over the past few years there is a layer above the quarry which produces beautiful, disassociated chunks of agatized bone.

Agatized or agate replaced dinosaur bone is a rare form of fossilized dinosaur bone where the original fossilized bone (typically permineralized with calcite) has been re-mineralized (replaced/substituted) with silica-type compounds (agate, jasper, chalcedony, or opal). In a unique and isolated circumstance, the strata on the Colorado Plateau were uplifted during the tertiary intrusions, about 35,000,000 years ago, when the San Rafael Swell and the La Sals, Henry, and Abajo Mountains were formed. As these ranges were forming, local strata layers were flooded with silica-rich, superheated groundwater. This provided the appropriate environment to begin the replacement of the calcite in the original fossils with silicates. The most prolific layers of gem bone come from the Morrison Formation which is late Jurassic in age.
