During an underwater study off the coast of California, marine researchers discovered a mammoth ivory dating back 100,000 years. Its protection allows the DNA of the sample to be used at low temperatures, away from light.
When operating an unmanned underwater vehicle (often called a ROV) Underwater long-distance vehicle), Oceanographers expect unscientific marine species to observe unprecedented behaviors between creatures or the amazing landscapes designed by life and currents. However, this is not the case , Working at the Monterey Bay Aquarium Research Institute. In 2019, they explored on one level At a depth of about 3,000 meters, 80 kilometers off the coast of California. Then they saw the shape of an ivory and were amazed. On their screens. During this trip they were unable to bring it fully to the surface because a piece was broken during the collection, which allowed the team to bring only part of this invention. In 2021, a new trip was made to the same site to bring back the remaining security.
This mammoth ivory is not the first to be found in the ocean. However, the earlier remains of mammoths found in the marine environment (North Sea) are not so deep and their location is not actually more than a few ten meters from the surface.
The remains of previous mammoths found in the marine environment are not so deep
Most of the mammoth remains that were excavated came from itOn the edge of the Arctic Circle or Farm, at the level of man-occupied hunting grounds. The presence of mammoth ivory at a depth of 3,000 meters is amazing, especially since its safety level is very good. This will make it possible to get pictures To do And perform analysis .
Witness a hybrid between two types of mammoths?
This ivory is about a meter long and once belonged to the Columbus mammoth. Mammootty Columbi. This species is known to be particularly native to North America (specimens found in Arizona, Texas and Florida), And Costa Rica. Estimates indicate that the breed is four meters high and long and weighs eight to ten tons. According to the thickness From And Researchers estimate that a person trained in ivory is over 100,000 years old. Analysis is underway to determine the exact age. The Not complete but will provide a better understanding of the evolution of mummies
The first mammoths actually came from Eurasia to North America via the Bering Strait 1.5 million years ago and then hybridized. When it merged with the United States millions of years later. This Would have allowed the species to appear M. Colombi The hypotheses are 420,000 years old. If the ivory of the specimen brought from the depths is as old as the researchers think, it will help to determine the age of this hybrid more accurately.
