Polished Agate Fossil Pine Cone Equicalastrobus from Western Sahara

These Pine (Seed) Cones are found in Eocene deposits that span from east of the Tinduf Basin in Algeria. Sporadically exposed in the dunes, these fossils were delicately preserved in translucent layers of clear chalcedony (a variety of micro-crystalline quartz). These have yet to be properly identified, however they closely resemble fruit (Pineapple) from the Chinle Formation in Arizona that have been designated to the genus Equicalastrobus.

Each of these specimens have been cut and polished by hand here at Ancient Earth. Hand selected for completeness and good mineralization, these were picked out of thousands that were offered for sale, while we visited the Western Sahara. Every one is unique in color and form making them wonderful study specimens or pieces for jewelry.
