Lovely polished Cotham Marble slices,
This ancient fossil marble is a type of Stromatolite, which were the first fossil evidence of life on Earth.
Essentially, cyanobacteria built up layers of sediment over time. The layers created by this can be seen in these polished slices.
They almost form a 'landscape' picture, usually with 'trees', which make a lovely display piece.
