This specimen has been part of my personal collection for over 10 years and originates from the world famous collection of "Barney Hansford" who was a prolific collector in the 1950's. This specimen has been re-polished to reveal the beautiful calcite chambers within.This is a very large and imposing display specimen and is an absolute classic from this world heritage site. The specimen also comes with a display stand. This would look fantastic in any interior or office space and is approximately 200 million years old. Larger pictures can be viewed in "Showcase Fossils".
