An ancient wolf was found superslot เครดิตฟรี frozen for 56,000 years, researchers have revealed, the oldest and most complete remains ever found, the journal Current Biology published the discovery of the remains of ancient wild puppies buried in permafrost. For more than 56,000 years in the Yukon Territory in Canada's westernmost region. It is the most complete and oldest wolves ever found.
The remains of the pup were found by a gold miner who was breaking through a frozen mud wall in the Klondike Gold Mine near Dawson City.
Julie Meechen, an anatomy expert at Des Moines University in Iowa, told CNN that the mummified remains are very complete. The whole skin is intact, most of the hair and all the soft tissues are intact. And the carcass of this wild puppy is about 56,000 years old.
This female forest calves are the oldest and most complete carcasses ever found. And allows researchers to find detailed information on how his life is likely to be
From the use of x-ray technology Experts concluded the puppy died between six and seven weeks, while stable isotope analysis technology found it alive during the melting glacier.
It was also found that the puppy's diet was influenced by its proximity to water. Most of the food is aquatic animals such as salmon or perhaps coastal birds
DNA analysis showed that The pup descended from ancient wild dogs from Russia, Siberia and Alaska, which are the ancestors of today's wild dogs.
The researchers also revealed that The formation of mummification in the freeze-stable soil layer requires a special environment. Must die on an area with a constant freeze of soil, where the ground is constantly frozen. And had to be buried quickly And with this perfect condition The experts therefore concluded that This puppy died suddenly. Which may be that the nest collapsed Since it was not malnourished before death
Despite the discovery of the remains of intact wild dogs in Siberia several times. But this ancient wild puppy was found rarely in North America.
