3.4" Cut & Polished Dinosaur Bone (Gembone) Section - Rare Yellow

This is a piece of high quality, red and yellow agatized, Late Jurassic aged dinosaur bone from Colorado. Yellow is one of the rarer colors to see in this material.

Part of one side has been polished to a mirror finish which allows for the beautiful internal cell structure to be easily seen. The small cells would be indicative of a non-theropod dinosaur, almost certainly one of the large Sauropods like Diplodocus or Camarasaurus which are common in the Morrison Formation.

Agatized dinosaur bone is a rare form of fossilized dinosaur bone where the original fossilized bone has been re-mineralized (replaced) with silica based compounds (agate, jasper, chalcedony, or opal).
