Baicalia capricornia Stromatolites from Australia

These Baicalia capricornia stromatolites from Australia are most esthetic with distinctly alternating dark and light purple-ish laminations, and an occasional rich red blotch. The formation from which it comes in Western Australia dates to the Mesoproterozoic, to a time when prokaryotes dominated life, building stromatolitic reefs This was a time when the use of sex on earth for reproduction and diversity had probably just begun in the early eukaryotic cells with nuclei.

The beautiful specimen has been hand polished to a mirror finish perpendicular to the very distinct laminae.
