TABLE 3. — As observed on the inner ramp of the Attard member: the relationship between taxonomic composition and structures of the rhodolith nucleus and of the other types of structure outward. For each type of rhodolith structures on the nucleus and outward is indicated the percentage of rhodoliths in which each coralline species occurs.
