The Interior Assemblage:                                    After (p.35), AMOCO Seminar on Stratigraphic Principles.    

    This assemblage is widely distributed through the central part of Florida Bay and seems to reflect the regime of fluctuating conditions between the extremes found along the margins of the Everglades to the north and the tidal areas to the south. It is characteristic of the bulk of the mud bank areas except in their very widest and shallowest parts. It appears to develop most characteristically in 1 - 6 feet of water. It exists far to the south along the tops of banks even where they are bordered by other, more open biotas.
