Agatized Dinosaur Gem Bone
Dinosaur Gembone from the Morrison formation of Colorado is either found as fragments on the surface from bones or partial bones that have long since been destroyed by exposure to the elements, or as broken, tumbled, chunks found in the event layers of the quarry. Determining the type of dinosaur these agatized bones come from is difficult in this formation, but can be possible to determine based on cell size and outer appearance of the bone.
