Weasels are small carnivores with a long body and short legs. They also have a stout skull and sharp teeth. These creatures, along with ferrets and minks, make up the Mustelinae subfamily. Until now, researchers believed that the oldest fossils from this family were from Poland and Germany, dating back to about 3.5 million years ago in the Pliocene epoch. But a fossil discovered in Teruel, Spain, has doubled that estimate, dating back to the late Miocene, around 6.5 million years ago.
