The rediscovered Hula painted frog of Israel has been called a "living fossil" after tests revealed that it belongs to a group of amphibians believed to have disappeared thousands of years ago. The frog, declared extinct in 1996, was thought to have been part of the Discoglossus group, but testing of living frogs found they are actually part of the Latonia group, which is thought to have gone extinct 15,000 years ago. "Nobody ever had a chance to see a Latonia because it went extinct in Europe. The only way anyone could see it was through looking at fossils. ... So this is a living fossil," said professor Sarig Gafny of Israel's Ruppin Academic Center.
