Dinosaur Bone
Fossil Dinosaur Bone is easily distinguished from other rocks. The cell structure of the bone is usually visible. This shows up as a honeycomb of holes. Some dinosaur bone is used in making jewelry. It takes a high polish and the patterns of the cell structure add to the beauty of the stone.
Dinosaurs or lived during the Jurassic and Cretaceous Periods of the Mesozoic era. Some Dinosaurs were carnivorous (meat eaters) and Some were herbivorous (plant eaters). Scientists divide dinosaurs into two groups: Saurischia (reptile hipped) and Ornithischia (bird hipped). Some dinosaurs had feathers. Most paleontologists believe that dinosaurs were the ancestors of todays birds. This bone is from the Jurassic Period.
