The Morrison Formation is a distinctive sequence of Late Jurassic (155 million years ago-148 million years ago) sedimentary rock which has been the most fertile source of dinosaur fossils in North America. It covers several states with significant fossil finds in Wyoming, Colorado, and Utah.
The term fossil refers to any preserved remains or imprint of a living organism (usually ancient), such as a bone, shell, footprint, or leaf impression. Most of the dinosaur fossils found today are mineralized bones, but they also include footprints, tracks, eggs, skin impressions, stomach stones, and fossilized feces (known as coprolites).
Fossilization usually occurred when a dinosaur died and was buried or covered over by a sediment of rock particles. Bones and teeth of the dinosaurs must undergo some form of mineralization to become fossils. The organic matter comprising the bones and teeth usually decays and is replaced by minerals such as silica, calcite, carbonates and iron. The cell structure of the bone is usually visible. This shows up in designer cabochons as a honeycomb of holes or polka dots.
Fossilized Dinosaur Bone semiprecious gemstone cabochons take a high polish and have a hardness of 7, which makes them very wearable.
Dinosaur Bone is believed to increase energy and improve memory. Dinosaur Bone is also believed to be good for calming anxiety, especially survival anxieties. It is said to help with communication and the ability to understand.
