Distribution of the ichnogenera, their relative abundance in the studied areas, and the bioerosion index (BI). The distribution of samples is plotted according the different sampling methods (see text for details). The sampled bathymetric range of the studied beds is also reported (depth intervals are dark gray for macroids and gray for rhodoliths). E, Entobia; G, Gastrochaenolites; T, Trypanites; T/M, Trypanites/Maeandropolydora; R, Rogerella; r, rare; c, common; a, abundant
