Halimeda Bioherms, Figure 5 (a) West to east seismic section across the outer Cooktown shelf showing bedded nature of the
Halimeda banks in 30 m of water. (b þ c) Uninterpreted and interpreted seismic section across the banks on the outer Cooktown
shelf. The multigenerational nature of the banks together with their planal Pleistocene growth surface clearly visible. (d) Seismic
section of thick Halimeda banks in the Makassar Strait, Java Sea. The banks are clearly sitting on a planar surface interpreted as the
Pleistocene.
