In the early 2000s, crews expanding Chile's Route 5 -- part of the Pan-American Highway -- blasted into a hillside a few kilometers north of the port city of Caldera and uncovered bones. Not human bones. Whale bones. Dozens of them, laid out in parallel rows as if arranged by some deliberate hand. The locals had long called this rise "Cerro Ballena" -- Whale Hill -- a name that turned out to be more literal than anyone had imagined. What the highway project revealed was one of the most extraordinary fossil sites on Earth: over 40 whale skeletons from the Late Miocene epoch, roughly 6 to 9 million years old, alongside the remains of seals, sharks, swordfish, and an animal that should not have been anywhere near an ocean -- an aquatic sloth.

Paleontologists led by Nicholas D. Pyenson, who published the site's definitive study in 2014, determined that the answer lay in the water itself. Iron-rich conditions in t...

The site contains fossils of pinnipeds -- including a dwarf seal species -- sailfish, sharks, and swordfish. Most unexpected are the remains of Thalassocnus, a genus of ground sloth that had adapted to life in the water. Thes...

But nobody formally reported the find, and the bones were forgotten for over 40 years. When the modern highway expansion reached Cerro Ballena, the project's environmenta...
