Notes: Semiquantitative analysis of microborer traces observed by SEM in corals, coralline algal crusts, and microbialites. Gray text = traces that are completely absent in the reef succession of the middle ranges. Photic indication = paleobathymetric interpretation derived from the ichnocoenosis in each sample. A = abundant, C = common, R = rare. Dys = dysphotic conditions, — = no microbioerosion.
