Researchers from China, Italy, and New Zealand documented whale fossils across sites in the Diamantina fracture zone at depths of 7 km, with some specimens dated to 5.3 million years ago. The findings, published in Nature, include a new whale species and an extinct beaked whale fossil recovered during 32 dives that sampled 485 locations. Supported claims derive primarily from BBC News reporting, while additional details remain unverified by New York Post.
