Scientists discover a giant whale graveyard in the Indian Ocean, revealing ancient fossils and mysterious deep‑sea life.

A team of researchers from China, Italy and New Zealand uncovered a 1,200‑km long whale graveyard in the southeastern Indian Ocean. The site lies 7 km below sea level and contains fossils that date back 5.3 million years, providing a fresh glimpse into extinct whale species. The discovery includes a rare beaked whale skeleton and a new species dubbed Pterocetus diamantinae. Diverse jellyfish, worms and crustaceans thrive around the carcasses, indicating a complex, long‑lived ecosystem. Experts say the find could inspire future deep‑sea explorations and expand knowledge of marine evolution.

A Massive Whale Graveyard Discovered in the Deep Ocean

Scientists found a vast underwater cemetery of whale bodies stretching 1,200 km (745 miles) across the southeastern Indian Ocean. The site, known as the Diamantina fracture zone, is 7 km deep and contains thousands of fossilized whale remains.

The bones date back 5.3 million years, making the graveyard older than many known fossils. The discovery, made by teams from China, Italy and New Zealand, included a skeleton of a Pterocetus benguelae and the largest find – a five‑metre NASA‑catalogued Antarctic minke whale carcass.

Researchers uncovered a new species called Pterocetus diamantinae, named after the discovery site. The area also hosts a community of marine life, including jellyfish, worms and crustaceans, that feed on the spread of carcasses.

"Discovering a necropolis of this scale was completely unexpected," said Xiaotong Peng, a lead scientist. "The size, depth and age range were far beyond anything we had imagined," he added.

Experts believe the find could trigger further dives and dig into the mysteries of deep‑sea ecosystems. Stephen J Godfrey, a marine biologist, said the site is a “trailer for an epic series of movies” and praised the team for their groundbreaking work.

Why it matters: This ancient whale graveyard gives scientists a snapshot of extinct species and shows the richness of life that can thrive around deep‑sea falls. The discovery encourages new exploration of the ocean’s hidden depths and offers fresh insights into evolutionary history.
