A living model of actively ramifying stromatolites, being a build-up of two hundred alternate layers: dark (organic) and light (mineral), was first obtained under laboratory conditions. Its formation was realized by means of copying fossil build-up morphology of Pre-Cambrian columnar stromatolites from the super-group of tungussids (Baicalia Kryl., Parmites Raab.) by means of artificial regulation of algobacterial film growth on the surface of a layer of mineral sediments.
