I have had a very successful season and as a result, there are only a handful of items currently available. My sincere apologies for this inconvenience!

I am working diligently to create more, but in the meantime, please enjoy the photos of this beautiful material and do not hesitate to contact me with any requests.

For centuries now, scientists have been recovering the fossilized remains of dinosaurs from every corner of the earth. Our understanding of these beasts has progressed from early misconceptions of huge, slow, stupid creatures to a present day appreciation of their remarkable intelligence, grace, diversity and majesty. We are witness to the most exciting period of dinosaur discovery and awareness in human history; with stunning new finds, fantastic computer animation, and a host of new theories presented to us on a regular basis. With great pleasure, I would like to introduce you to yet another wonder in the ever unfolding dinosaur saga:

Agatized Dinosaur Bone is a unique and extremely rare form of fossilized dinosaur bone that is only found within the Brushy Basin Member of the Morrison Formation, located on the Colorado Plateau. The latest dating of the Morrison Formation identifies it as approximately 146 to 156 million years old. The Brushy Basin was the last member of the Morrison Formation to be deposited, correlating with the Late Jurassic Age. The dinosaurs represented here include Allosaurus, Apatosaurus, Brachiosaurus, Camarasaurus, Diplodocus, Stegosaurus, and Torvosaurus (a theropod nearly the size of Tyrannosaurus), to name just a few!

It is now illegal to collect vertebrate fossils and paleontological resources from state and federal lands. My material was bought from local rock shops who have been selling this material for decades.

The following photos are macro photographs of some of the agatized bone exhibited elsewhere in this website. The high magnification reveals the beautiful inner structure, stunning color ranges, and fantastic agatization patterns within bone. These photos are best viewed at maximum magnification. Enjoy!!

My name is Kenneth (Ken) Kolb. I live in beautiful Moab, Utah, the heart of American dinosaur country.

As The StoneCarver, I have been working with dinosaur bone and refining my techniques for over 35 years. Endlessly inspired by the mystery and beauty of this material, I proudly offer an exceptional variety of the finest agatized bone exquisitely crafted into jewelry, specimens, and sculpted forms.

Each item is a piece of history and a work of art. You are invited to become the curator of this rare, non-renewable natural resource. What you can now hold in the palm of your hand is truly the "Legacy of the Dinosaur!"

Art and Jewelry provide the best opportunity to show off the truly incredible beauty of Agatized Dinosaur Bone. A specimen piece needs to be esthetically pleasing, which requires a combination of color, structure and form. Most available bone does not meet these criteria. Art and jewelry, on the other hand, allow the craftsman to work with broken blocks and shards and select the finest material from within. Fractures can be worked around, pitted regions can be avoided, and areas of poor structure or color development can be rejected. What is left is the best of the best. But even this is not enough to completely bring out the inner beauty of bone. Inspired craftsmanship and a rich, warm, lustrous polish are required to make Agatized Dinosaur Bone come alive again. Remember, this material is 146,000,000 to 156,000,000 years old!

It takes me a long time to complete some of these pieces and most of them sell rather quickly once completed. As such, most of the items seen in this website are no longer available. I've left them here to display the amazing color variety and the scope of my work. Since no two pieces of bone have the exact same colors, I cannot duplicate sold pieces with new work of the same color. However, I can offer other color choices that will be just as beautiful. Contact me for information!

Some of the work shown on this site is available exclusively through Etsy or eBay, on-line sale sites. If you are interested in purchasing any available item, a link has been provided which will either re-direct you to the item location or send you directly to PayPal, my preferred payment method, for immediate purchase.



I will ship international, but I will need to invoice you first to provide appropriate shipping charges. Most international sales will be shipped USPS Priority Mail with a small mark-up for handling.

The BoneMasters started out as a group of artisans specializing in the carving and polishing of agatized dinosaur bone. As the current economy took its toll, the other members of this website have moved on to different ventures. The StoneCarver is the only current member of this group, although hopefully that will change in the future!
