In 2019, scientists from Monterey Bay Aquarium Research Institute They were exploring an underwater mountain about 10,000 feet deep and nearly 200 miles from shore using a remotely operated vehicle.
The researchers saw what appeared to be elephant tusks and were able to take a small piece of the tusk at the time, but returned this summer to retrieve 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 that the tusk was in fact the property of a Columbian mammoth.
The researchers said the cold environment and high pressure in the deep sea helped keep the ancient tusk, which was more than 3 feet long, intact.
In 34 years of searching the deep sea, this may be one of our most unique discoveries to date: an ancient mammoth tusk.

“The deep-sea conservation environment for this specimen is different from almost anything we’ve seen elsewhere,” said University of Michigan paleontologist Daniel Fisher. in the current situation.
“Other mammoths have been recovered from the ocean, but generally not from depths of more than a few tens of metres,” Fisher said.
Research is underway to extract more information from Knapp. Scientists use CT scans of the canines to determine how old the animal was and how it ended up in the deep sea.
The research team believes that this find could be the oldest well-preserved giant tusk recovered from this region of North America. The canine is dated and estimated to be more than 100,000 years old.
“You start to ‘expect the unexpected’ when exploring the deep sea, but I’m still amazed that we found an ancient mammoth tusk,” said Stephen Haddock, chief scientist at the Monterey Institute.
The Colombian mammoth roamed the Americas as far north as the northern United States and as far south as Costa Rica. The species became extinct about 11,500 years ago.
