Marine biologists are hoping to discover all kinds of strange things in the deep ocean, but they are not a huge horn.

Marine biologist Steven Haddock and ROV pilot Randy Prickett saw the horn in 2019 in the R / V. Western Flyer, and it looks like they ‘d I met an ivory tower. The two, as members of the Monterey Bay Aquarium Research Institute (MBARI), were exploring a steep mountain some 200 miles[300 km]off the coast of California.

Haddock and Prickett returned to their place in July 2021, having just taken a small portion of the hive on their first trip. Using ROV Doc Ricketts and work deeper than 10,000 feet (3,070 meters), was able to collect 3-foot-tall (1-meter) horns, according to MBARI Press release. Back on the surface, the team was able to confirm that the horn belonged to an extinct Columbian mammoth (Mammuthus columbi).

“In the deep ocean, we find so many amazing animals that people can’t believe they exist on Earth, but finding this great horn, so deep and so far from the shoreline, was the hardest thing I’ve ever had,” Haddock said. to me in email.

“When we realized that this was a huge animal, my head started to spin and I imagined what it was like to be on the surface of this distant ocean,” he added. “I still find it hard to believe how it was thousands of years without being destroyed or buried before it stumbled.”

Good storage of content-timeless great horns made possible by the cold,The depth of the ocean, which is “unlike anything we have seen anywhere else,” Daniel Fisher, a paleontologist at the University of Michigan and a member of the research team, explained in the article. Some mammoths have been seized from the sea, but usually not more than a few feet deep. ”

It is difficult to know how a bull produces it ended up very far from the coast, but scientists have seen this before. Carcasses of corpses, whether from Cretaceous dinosaurs or modern crocodiles, sometimes sinking under the sea washed into the sea, whether by waves, floods, or tsunamis. It happens.

A team of diverse scientists, including paleontologists, geneticists, oceanographers, and geochronologists, are now preparing to investigate the conflict from a variety of backgrounds. CT scans provide 3D visualization, revealing its structure and interior. The team will also try to remove and track mammoth DNA. Taken together, these methods can help us to better understand the animal’s history, age, and ancestry. Most importantly, they It may also reveal new information on the evolution and spread of mammoths in North America.

Haddock and Fisher, along with marine experts at UC Santa Cruz, are trying to reduce the potential for landslides where mammoths would emerge. The salty feet of the sea can indicate how long it has been under the sea, while the tides of the old ocean currents may point to the origin of the shores. “We were wondering if it would leave Alaska, or take the shortest route off the coast of California. Be careful to get our results,” Haddock told me.

Of course, all of this is very original, as scientists take this opportunity to announce the availability of this model and to reveal selected research methods. This beehive has stories to tell, and we look forward to more.
