A Stromatolite Built by a Phormidium-Like Alga from the Lower Carboniferous of South Wales

Much is now known about the compositions of modern stromatolite-building communities (see review by Golubic 1976). Such stromatolites, although from widely separated areas, are built by a limited number of micro-organisms. These often possess special adaptations which allow them to survive under the rather special conditions in which they live. Many forms inhabiting intertidal settings for example produce gel envelopes which enables them to resist desiccation, while other forms exhibit motility which helps prevent burial by sediment (Golubic and Campbell 1979).
