Stromatolites that commonly occur in carbonate rocks vary considerably in age from the Early Precambrian to the Quaternary Period. Numerous stromatolite sites on the European continent usually do not attract great attention of scientists because these fossils are of little significance for stratigraphic study. However, as there are no other paleontological sites in Precambrian rocks, stromatolites can and should be used as lithologo-paleontological markers. Some examples of European stromatolites, occurring on different stratigraphic levels, are discussed. A spatial distribution scheme of stromatolites, showing the geographic coordinates of each point, is presented. It is emphasized that data on stromatolites should be classified and analysed more thoroughly.
