Preserved Ice Age puppies awe scientists worldwide

The hunters searching for mammoth tusks were drawn to the steep riverbank by a deposit of ancient bones. To their astonishment, they discovered an Ice Age puppy's snout peeking out from the permafrost.

Five years later, a pair of puppies perfectly preserved in Russia's far northeast region of Yakutia and dating 12,460 years has excited scientists worldwide.

"To find a carnivorous mammal intact with skin, fur and internal organs - this has never happened before," said Sergei Fyodorov, head of exhibitions at the Mammoth Museum of North-Eastern Federal University in the regional capital of Yakutsk.
