Footage of the baby mammoth in the story reported by @Erinaceus above.
Miners digging for gold in Canada's Yukon discovered a near-perfect mummified baby woolly mammoth believed to be over 30,000 years old.

This project seems to have gained yet another funding boost from a new investor - the CIA.

When did they become extinct? The debate continues. Are the experts on the horns of a dilemma or do they face an impossible tusk?
Some ancient DNA may be leading paleontologists astray in attempts to date when woolly mammoths and woolly rhinos went extinct.
In 2021, an analysis of plant and animal DNA from sediment samples from the Arctic, spanning about the last 50,000 years, suggested that mammoths survived in north-central Siberia as late as about 3,900 years ago (SN: 1/11/22). That’s much later than when the youngest mammoth fossil found in continental Eurasia suggests the animals died out; it dates to about 10,700 years ago. Only on Wrangel Island off the coast of Siberia and the Pribilof Islands in the Bering Sea were mammoths known to have survived later.
The finding was one of several in recent years using ancient DNA found in sediment and other environmental material to suggest new insights into animal extinctions. Genetic evidence from woolly rhinos in Eurasia and horses in Alaska have also indicated that these animals remained thousands of years longer in some areas than was thought.
But thousands of years is also how long the animals’ large bones can linger on the ground in the frigid north, slowly weathering and shedding tiny bits of DNA, two researchers write November 30 in Nature.
That means that the youngest ancient DNA in sediment samples may have come from such bones, not living mammoths, woolly rhinos and other megafauna. Studies that rely on this genetic evidence could skew estimates of when these animals went extinct by thousands of years toward the present, say paleontologists Joshua Miller of the University of Cincinnati and Carl Simpson of the University of Colorado Boulder.
When, and why, mammoths and some other Ice Age creatures died out is a lingering mystery. Dating when these animals went extinct could help reveal what drove them to their demise — humans, a warming climate, some combination of the two or something else entirely (SN: 11/13/18; SN: 8/13/20). ...

How they became as fluffy as bunnies.
As wooly mammoths grazed frigid Siberian steppes for more than half a million years, they evolved increasingly fluffy fur, large fat deposits, and smaller ears, according to a new study.
By comparing the genomes of modern elephants with those of multiple wooly mammoths – including individual mammoths that lived 600,000 years apart – researchers gained new insight into the evolution of these ice-age icons.
Distinctive features like fluffy fur and fat deposits were already genetically encoded in early wooly mammoths, the study found, but these and other characteristics seem to have grown more pronounced as the mammoths adapted to Siberia over hundreds of millennia.
"We wanted to know what makes a mammoth a wooly mammoth," says paleogeneticist and first author David Díez-del-Molino from the Center for Paleogenetics in Stockholm.
In addition to finding genetic evidence of fluffier fur and small ears, "there are also many other adaptations like fat metabolism and cold perception that are not so evident because they're at the molecular level," he adds.

Mammoth tusk found in Cambridgeshire
On July 11, Jamie Jordan and his colleague, Sarah Moore, were on a ‘fossil walk’ searching for samples in a quarry when they noticed a ‘tube-like structure’ popping out of the sand.
They were initially unsure what it was but quickly realised it was a mammoth tusk.

Mammoth tooth found on Essex beach
Chris Bien, 56, was visiting Holland-on-Sea, as part of her birthday celebrations when she took a walk on the beach with her husband Mark. Mrs Bien, from Goring-by-Sea, West Sussex, stopped to sit on a rock by the water's edge when she looked down and saw a wavy line pattern in the gravel.
