Rhodolith communities contribute significantly to the global calcium carbonate budget, and fossil rhodoliths are commonly used to obtain paleoecologic and paleoclimatic information. [ 17 ] [ 18 ] [ 19 ] Under the right circumstances, rhodoliths can be the main carbonate sediment producers, [ 20 ] [ 21 ] often forming rudstone or floatstone beds ...
