Newest cabochon of fossilized dinosaur bone from Utah

Newest cabochon of fossilized dinosaur bone from Utah.  You can clearly see where minerals replaced the cells.  Most of this material is found in the Utah/Colorado area.  When the dinosaurs died, the bodies would be carried downstream and formed a dinosaur "log jam"-where the bodies were quickly covered with river silt.  I think Carol mentioned 20 million years ago for those events.  The Colorado/Utah area was a swamp at that time with many river systems running through it, not the dry and dusty land it is today.

Another new addition is a black obsidian cabochon with one snowflake in the corner.  I kept on getting my mug in the picture because of a high shine.  First world problem there....
