Stromatolite fossil

Fossil stromatolites Formally defined, a stromatolite is an accretionary organosedimentary structure, commonly thinly layered, megascopic, and calcareous, produced by the activities of mat-building communities of mucilage-secreting microorganisms, filamentous and coccoid photoautotrophic prokaryotes such as cyanobacteria. Are all fossil stromatolites biological? by Michael J. Oard. Figure 1. A claimed stromatolite around an eroded upright log at the ‘fossil forest’ at Lulworth Cove, southern England. From a creation science perspective there are still many details of the rock and fossil record to work out.

Fossilized stromatolites, about 425 million years old, in the Soeginina Beds (Paadla Formation, Ludlow, Silurian) near Kübassaare, Estonia. Stromatolites are layered biochemical accretionary structures formed in shallow water by the trapping, binding and cementation of sedimentary grains in biofilms (specifically microbial mats), especially cyanobacteria. These fossils are mounds composed of sediment and cyanobacteria. Stromatolites are preserved when sediment is trapped and the algae grow over and through this sediment, creating alternating layers of algal mat and sediment. These often form mounds and columns that when grouped together form a type of reef called a bioherm.

Left: Stromatolites (Hoyt Limestone, Upper Cambrian, New York, USA) Right: Polished kambaba jasper Thin-film and X-ray diffraction analysis done EPI (Germany’s gemstone testing institute) shows the Kambaba jasper is a rhyolite of volcanic origin and thus can not be a stromatolite. It's quartz on lace agate on stromatolite fossil.
