Aussie researchers discover Indian Ocean 'shark graveyard'
December 07, 2022

Researchers from Australia's national science agency have discovered a shark graveyard on the floor of the Indian Ocean.

The Commonwealth Scientific and Industrial Research Organisation revealed some of the finds by researchers conducting biodiversity surveys of two of the country's newest marine parks on board the research vessel Investigator.

The teeth belonged to not only modern sharks, including mako and white sharks, but also prehistoric species such as an ancestor of the megalodon - a giant species that died out approximately 3.5 million years ago.
