Scientists expose 75,000 -year -old ancient Arctic animals in Norwegian cave

Scientists have revealed the remains of a vast animals living in the European Arctic 75,000 years ago.

46 types of animal bones – including stars, fish and birds, were discovered in a cave on the coast of northern Norway, which represents the oldest example of the animal community in the European Arctic during this warm era.

Have appeared in the results National Academy of Sciences (PNA) action.

The research team believes that bones will help scientists understand that forest life once responded to dramatic climate changes, insights that will be extremely related to the protection work today.

“These discoveries provide a rare snapshot in the world,” said Dr. Sam Walker and Oslo University of Bornemoth University. He added, “They also point to the extent to which cold species can be jeopardized, which changes the climate conditions, which can help us to understand their elasticity and risk of extinction at present.”

The animals that were identified as polar beer, Wallers, Bow Head Wheel, Atlantic Puffin, Common Admire, Rock Pettermigan and Atlantic Codest Democracy. The team also found a colide lemons, which is a species that have now disappeared in Europe and has never been found in Scandinavia.

DNA testing also found that when the cold conditions returned, the animals could not survive.

“How we had an Arctic life in this period, lacking over 10,000 years of age,” said Professor Sanne Bosnol, senior author of Oslo University. He added, “The cave has now revealed various animals in the coastal ecosystem that represent both the maritime and the environment.”

In the 1990s, the Arn Qimgrota cave was discovered, when a local mining industry made a tunnel from a nearby mountain. It has been widespread for almost 30 years when the research team excavated a huge excavation in 2021 and 2022 and discovered the secrets of the cave.

Various types of animals suggest that after the glacier melt, the coast was currently widely free of snow. This will provide a suitable residence for the migrant polar deer, which he discovered.

The presence of sweet water fish means that there are lakes and rivers inside the tundra, and for some adventurers, sea snow from the coast, such as bohde wheel and valros. Sea snow was likely to be seasonal because the portpice of the port, which is also found in animal remains, is known to avoid snow.

Although these animals made the region colonial after the melting of glaciers during this period, it seems that when the snow came back and covered the landscape, they could not migrate to the alternative ecosystem.

Dr. Walker said, “It is highlighted how the cold -consuming species have struggled to adopt major climate events. It is directly related to the challenges in the Arctic that they face in the Arctic because the climate is warm.” He added, “These animals in the region nowadays are more fractures than 75,000 years ago, so it is also difficult to move and adapt to the animal population.”

“It is also important to note that it was a change towards the cold, not the period of warming that we are facing today,” said Professor Bosnicol. They concluded, “And these are cold-adaptive species-so if they struggle to deal with cold periods in the past, it will be difficult for these species to adapt to the heat climate.”

The study was a collaboration between the University of Oslo, the University of Bornemoth, the University of Museum of Bergen, the University of Life Sciences of Norway, and other institutions.
