Yukon paleontologists unveiled a mummified Arctic ground squirrel from the Ice Age, estimated to be about 30,000 years old, and curled up in a ball as though it died while hibernating.
Arctic ground squirrels — still common in Yukon today — make nests, or middens, underground for hibernation and Zazula says Ice Age nests are regularly found preserved in the Klondike permafrost. A full squirrel, though, is far more unusual.
"Animals that we have here today are actually pretty tough, because they've had to endure these numerous changes in the past. So that's a really important lesson in terms of trying to think about how future climate change will impact these animals," Zazula said.X-ray shows specimen in 'great condition'
"I'm really impressed that someone recognized it for what it was. From the outside, it just kind of looks like a brown blob. It looks a bit like a brown rock."Heath wasn't sure an X-ray would show much. The animal was so "bunched up," she said, and sometimes the bones of mummified animals have lost calcium over time, making X-rays less clear.
