Notes

It is not possible to be 100% certain, but it is highly likely that the spine is one of the dorsal fin spines of a large billfish such as a Marlin.

Fish Section staff compared the spine with the dorsal fin spines of the 190 cm long Marlin skeleton in the Australian Museum Skeleton Gallery. They were almost identical.
