FREE: Fossil Pyrite Sun

The listing, Fossil Pyrite Sun has ended.

These beautiful pyrite fossils are very unique and are known as "suns", also known as pyrite dollars, which exhibit striations radiating out from the center like rays of the sun. These unique specimens are recovered from underground coal mines near Sparta, Randolph County, Illinois USA, where they occur in narrow, compacted seams of slate interbedded in 300 million-year-old Pennsylvanian Period coal deposits. The origin of pyrite suns has been a subject of speculation and debate. While some authorities have speculated they originated as fossils that were subsequently replaced with pyrite, the current consensus is they are concretions spread out under pressure and forced to grow in a laterally compressed, radiating manner in the seams of slate.

This one is beautiful measuring 3" across. Very collectible piece for your collection.
