Chinese Scientists Find 10 Million Dead Whales in 660-Mile Indian Ocean Graveyard

Summary
Nearly 500 whale skeletons were recorded in the Diamantina Fracture Zone about 20,000 feet down, making it the largest whale graveyard yet identified.
Researchers estimate roughly 10 million dead whales may lie across the 660-mile area, after submersible dives recovered 485 bones including fossils dated to 5.3 million years ago.
Beaked whales appear to dominate the site, while skulls identified two extinct species—Pterocetus and Izikoziphius—and bones from a sei whale and an Antarctic minke whale were also found.
Thousands of bivalves, brittle stars, worms and jellyfish clustered around the remains, with some species possibly new to science and resembling fauna seen at hydrothermal vents.
The team said the find supports the idea that whale falls serve as deep-sea evolutionary hotspots and stepping stones for sulfide-dependent life in the ocean.
How does a 5-million-year-old graveyard for millions of whales become a thriving cradle for undiscovered deep-sea life?
Will this vibrant deep-sea ecosystem, a massive carbon sink, halt the global rush for deep-sea mining?
World's Largest Whale Graveyard Discovered: 1,200 km Diamantina Zone Reveals Deep-Sea Evolution and Carbon Sink
Overview
The Diamantina Zone whale necropolis, recently discovered in the southeastern Indian Ocean, is the world's largest whale graveyard. Stretching about 1,200 kilometers along the seafloor at depths between 4,616 and 7,001 meters, this site contains a remarkable collection of both modern and ancient whale remains. Researchers found five modern whale-fall communities and hundreds of fossil cetaceans, making it a significant landmark in marine biology and paleontology. The sheer scale and density of the remains provide scientists with a unique opportunity to study deep-sea ecosystems and the evolutionary history of whales.
