Products description

Here is a large Stromatolite plate of the genus Greysonia from the upper Cretaceous of Bolivia. These Stromatolites have been on the fossil market for decades. Mostly they falsely advertised as from the Precambrian, Ediacarium. However,  these stromatolites are been found in the Miraflores formation that corresponds to a lower cretaceous age. *
The Bolivian Stromatolites are nevertheless one of the most decorative Stromatolites. This piece is a large and especially beautiful Stromatolite slice that has been polished on both sides
