AI Summary

Researchers have uncovered a significant whale graveyard in the Diamantina Fracture Zone of the Indian Ocean, containing hundreds of fossils, including a newly identified species. This site, measuring approximately 746 miles long, has been accumulating remains for at least 5 million years, primarily from beaked whales. The expedition, part of the Global Hadal Trench Exploration Program, revealed a staggering estimate of over 10 million whale remains on the ocean floor, with some areas containing up to 760 fossils per square kilometer. The findings highlight the ecological importance of whale falls, which support diverse deep-sea life, and provide new insights into cetacean habitats and migration patterns.

Key Details: • The graveyard is located in the Diamantina Fracture Zone, southwest of Australia. • Researchers conducted 32 dives between February and March 2023. • The site has an estimated density of 760 fossils per square kilometer. • One modern whale fall contained up to 2,840 organisms in a single square meter.
