5.3-million-year-old ‘whale graveyard’ has been hiding at the bottom of the Indian Ocean: Scientists call it ‘unexpected’

Researchers discovered a vast whale graveyard in the Indian Ocean’s Diamantina Zone, containing 476 fossil cetaceans and five modern whale-fall communities. This site, active for at least 5.3 million years, provides a unique window into deep-sea ecosystems and carbon sequestration, with many species potentially new to science.
