Ancient mammoth tusk discovered 10,000 feet deep in ocean off California coast

In 2019, scientists from the Monterey Bay Aquarium Research Institute were exploring an underwater mountain around 10,000 feet deep and nearly 200 miles offshore with a remotely operated vehicle. The researchers saw what appeared to be an elephant tusk and managed to take a small piece of the tusk at the time, but returned this summer to recover the entire specimen.

With the help of researchers from the University of California, Santa Cruz and the University of Michigan who examined the find, scientists confirmed last week the tusk actually once belonged to a Columbian mammoth. Researchers said the deep sea’s cold, high-pressure environment helped keep the ancient tusk, which measures more than 3 feet in length, intact.

Research is underway to extract more information from the tusk. Scientists are using CT scans of the tusk to determine the animal’s age and how it may have ended up deep offshore. The research team believes the discovery could be the oldest well-preserved mammoth tusk recovered from this region of North America.
Dating of the tusk is underway and it’s estimated to be more than 100,000 years old.

“You start to ‘expect the unexpected’ when exploring the deep sea, but I’m still stunned that we came upon the ancient tusk of a mammoth,” Steven Haddock, senior scientist with the Monterey Institute, said. The Columbian mammoth roamed the Americas as far north as the Northern U.S. and as far south as Costa Rica. The species went extinct some 11,500 years ago.

A mammoth stuck on an ice floe? Live mammoth caught in a riptide current or washed off shore from a tsunami, or a dead mammoth body washed down a river, and carried out to sea? Tusk clenched in the teeth of a shark as a keepsake? Sharknado? Ancient astronauts? Giant fusion-powered albatrosses? The mind reels.
