The remains of a 50,000-year-old baby mammoth unearthed from melting permafrost have been unveiled to the public by researchers in Russia's Siberia region, calling it the best-preserved mammoth body ever discovered.Nicknamed Yana, the female mammoth weighs more than 100 kilograms (220 pounds) and measures 120 centimeters (47 inches).Scientists believe Yana was 1 year old when she died. Her remains are one of only seven mammoth carcasses found in the world.

The remains were displayed to the scientific community on Monday at the North-Eastern Federal University in Yakutsk, the regional capital, the university said in a statement.

According to Agence France-Presse, the female mammoth was named Yana after the river in which it was found, in Yakutia, a sparsely populated region in the Russian Middle East. "We were all surprised by the state of preservation of this mammoth; there was no damage to the body, trunk, ears or cheek, and there was no obvious damage or deformity," university president Anatoly Nikolaev said in the statement.

Its remains, dating back 50,000 years, were discovered last summer on the grounds of the Batagaika Research Station, where other remains of prehistoric animals had previously been found.

Yana was discovered in the melting permafrost of the Batagaika crater in the Yakutia region of Russia's far east. Known as the "gate to hell," the crater is 1 kilometer deep and has previously revealed the remains of other ancient animals, including bison, horses and dogs.As the permafrost thaws due to climate change, more and more parts of prehistoric animals are being discovered.Yana will be studied by scientists at the North-Eastern Federal University of Russia, which has a research center and museum dedicated to mammoths.

In Yakutia, an isolated region of more than 3 million square kilometers bordered by the Arctic Ocean, permafrost acts as a giant freezer that preserves prehistoric animals, especially mammoths.

The university called the discovery "remarkable" and said it will give researchers new insights into how mammoths lived and adapted to their environment.

“We were all surprised by the state of preservation of this mammoth,” university rector Anatoly Nikolaev said in the statement. “There was no damage to the body, trunk, ears or cheek, and there was no obvious damage or deformity.”

Before Yana, only six mammoth carcasses had been found in the world: five in Russia and one in Canada, according to the university.
