Scientific reports of the Belgian expedition on the Australian Great Barrier Reefs, 1967. Sedimentology: 2 Monospecific stromatolites from the Great Barrier Reef tract and their paleontological significance

Uncalcified stromatolites built by the blue green alga Phormidium hendersonnii are presently growing on the outer reef flats of the ribbon reefs, Great Barrier Reefs, Australia. They show a noctihemeral lamination which may be complicated by currents and tidal influences. They represent a unique worldwide Recent stromatolitic population which may help us understanding the Phanerozoic evolution of stromatolites and their present day limited distribution in seawaters.
