Accumulations of charophyte calcified oospheres, the gyrogonites, were previously usually interpreted as indicators of lowered salinity, however, many charophyte species from the Devonian sections have been found to be associated with typical marine assemblages, showing that the first representatives of the Charophyta were adapted to a wider variety of sedimentary environments than their modern relatives (Georgescu & Braun 2006).
