The palaeoecological assemblages of the PSRC are representative of inner-shelf reef communities across the central GBR, which are characterised by mixed assemblages of acroporids (Montipora, and locally abundant Acropora), dendrophyllids (Turbinaria), euphylliids (Euphyllia and Galaxea), and poritids (Goniopora and Porites). The composition of
inner-shelf coral communities distinguishes them from those associated with mid- and outer-shelf reefs, which are predominantly characterised by assemblages of Acropora
