This is genuine Petrified Dinosaur Bone from 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 as a honeycomb of holes.
