The specimen pieces I offer are just that: shards, blocks, or fragments of dinosaur bone that someone, at some point in time, picked up in the high desert region of the Colorado Plateau. Some of this material is agatized (gembone), much of it is calcified. I have sorted through many tons of broken bone material and selected pieces that had interesting features, definitive structure, and in many cases are esthetically pleasing!
This particular piece is a fascinating shard with lots of curves, ridges, and detail.
