Scientists have discovered an extensive whale graveyard in the Indian Ocean, stretching approximately 745 miles. The site contains whale remains dating back as far as 5.3 million years. This unprecedented find is considered one of the most significant discoveries of its kind, offering potential insights into the ancient history of whales and life in the largely unexplored depths of the ocean. The research, published in the journal *Nature*, details the scale and age of the fossilized remains. Experts believe the location served as a breeding and feeding ground for whales over millions of years, leading to a concentrated accumulation of carcasses. Further study of the graveyard could reveal information about past environmental conditions and whale evolution. The discovery highlights the vastness of what remains unknown about the ocean floor and its hidden history.
