Figure 4: Modern observations of Porites sp. used to constrain depth distributions.

(a) Map of fossil (red, open circles) and modern Porites sp. observations (plotted only those observations used to derived the depth distributions) (grey, filled circles). (b) Global (grey), basin and sub-basin (pink) depth distributions for Porites sp. represented as relative probability (normalised histograms, left panels) and cumulative frequency distributions (right panels): (i) ‘Global’ (grey) and Pacific (blue); (ii) ‘Global’ (grey) and Great Barrier Reef (orange); (iii) ‘Global’ (grey) and Caribbean (green); (iv) Caribbean (green) and Belize (orange).
