Scientists work to discover how more than 75 whale fossils were buried in the Atacama desert.
In Chile’s northern desert of Atacama scientists uncovering the remains of a massive whale graveyard are struggling with one question: how did more than 75 of the ocean giants end up just yards apart on a hill half a mile from the ocean?
In Chile’s northern desert of Atacama scientists uncovering the remains of a massive whale graveyard are struggling with one question: how did more than 75 of the ocean giants end up just yards apart on a hill half a mile from the ocean?
“We have a unique opportunity to develop a great scientific project and make a great contribution to science,” Mario Suarez, co-director of the investigation, told the Associated Press.
The research team said that the whales most likely died between 2 million and 7 million years ago, at which time the Atacama was a “lagoon-like environment.”
Still, there are numerous theories to explain the mass burial.
“I think they died more or less at the same time,” Nicholas Pyenson, co-director of the project and curator of fossil marine mammals at the Smithsonian's National Museum of Natural History, told Associated Press.
Pysen said that the there were numerous explanations for the mass burial. In one scenario, the whales driven into a lagoon by a storm. In another they were trapped in a bay after a landslide or earthquake blocked of access to the ocean.
So far, more than 75 whale fossils have been discovered. But Suarez believes there could be enough fossils still hidden beneath the sand to keep him working on the site for the rest of his career.
To date the discoveries have included more than 20 perfectly intact skeletons as well as the remains of a species of tusked dolphin that previously had only been discovered in Peru.
Suarez, director of the Paleontological Museum in the nearby town of Caldera, has known about the site for years, but said he was unaware of how unique it was since no excavation work had been undertaken.
The digging began last year when workers began widening the Pan American highway into the whale graveyard. Suarez was asked by the company to monitor the site and began lobbying for the protection of the fossils.
Chile’s government has since declared the site a protected area and the research team hopes to house the fossils in a museum close to the area.
