For 5 million years, whales have come to this place in the Indian Ocean to die

Lead

A team of deep-sea explorers has discovered an enormous whale graveyard in the southeastern Indian Ocean, a site that scientists say is the Earth's deepest and most extensive known accumulation of whale fossils and carcasses. The finding, reported by researchers from China, Italy, and New Zealand, was published in the peer-reviewed journal Nature on Wednesday.

Located in the Diamantina Fracture Zone, the site is approximately 1,200 kilometres (745 miles) long and 7 kilometres (4 miles) deep, according to a report by the BBC. Some remains at the site date back about 5.3 million years, as noted in both the BBC and South China Morning Post accounts.

Coverage Comparison

Two outlets have covered the discovery with distinct emphases. The BBC framed the find as a sensational breakthrough, highlighting the scale and age of the graveyard and quoting study authors and outside experts. The South China Morning Post presented the discovery as a scientific milestone, focusing on the unique ecosystem and the collaborative research effort.

Both outlets reported that the site is in the Diamantina Fracture Zone and that some fossils are about 5.3 million years old. The BBC provided specific dimensions—1,200 kilometres long and 7 kilometres deep—while the South China Morning Post emphasized that this is the largest whale-fall site recorded in the Indian Ocean and the deepest and most extensive known accumulation of this kind anywhere.

Key Claims

• The site is the largest whale-fall site ever recorded in the Indian Ocean, described as the Earth's deepest and most extensive known accumulation of whale fossils and carcasses, according to both the BBC and South China Morning Post.
• Located in the Diamantina Fracture Zone in the Indian Ocean, as reported by both outlets.
• Some fossils date back about 5.3 million years, as stated by both sources.
• The site is approximately 1,200 kilometres long and 7 kilometres deep, a claim carried by the BBC.
• A new species called Pterocetus diamantinae, named after the site, was discovered, as reported by the BBC.
• A 5-metre long Antarctic minke whale's carcass was found at the site, according to the BBC.
• The study was conducted by researchers from the Chinese Academy of Sciences, with collaborators from the University of Pisa and Earth Sciences New Zealand, as detailed in the South China Morning Post article.
• Xiaotong Peng of the Chinese Academy of Sciences, one of the study's authors, said: "Discovering a necropolis of this scale was completely unexpected." This quote appeared in the BBC report.

Perspectives

The discovery has been met with enthusiasm from the scientific community. Xiaotong Peng of the Chinese Academy of Sciences, a study co-author, told the BBC, "Discovering a necropolis of this scale was completely unexpected. The size of distribution, the depth and the age range were far beyond anything we had imagined."

Stephen J Godfrey of the Calvert Marine Museum, writing in Nature, called the find "a truly unique discovery," adding that although the site has limited accessibility, "it seems likely to hold many other exciting finds, and it will no doubt inspire more submersible dives in similar environments." The paper itself states that these findings "reshape the understanding of the limits and biogeography of whale-fall ecosystems and establish some deep-sea floors as a fossil archive for tracing cetacean evolution over geological time."
