Agatized Dinosaur Tail Vertebrae Bone. Agatized dinosaur bone occurs when the hollow bone structure of the dinosaur is replaced by quartz and trace minerals such as iron over millions of years. The best quality agatized dinosaur bone comes from the Jurassic era in Utah, from the 150 million year old Morrison Formation. The vast majority of the dinosaur bone found is just broken fragments; rarely is an identifiable bone found such as this 5 x 4 x 6 inch sauropod tail vertebrae. The tail vertebrae are pretty much complete except for the neural spine process. Only the top of this rare dinosaur bone has been polished to reveal the bone structure. The individual cells in the center of the bone are distinct and range in color from white calcite to many shades of brown, all the way up to orange. This impressive fossil stands on its own on the backside of the vertebrae. Estimated Value $600 - UP
