SANTIAGO (Reuters) - Chilean scientists have rediscovered a species of frog last seen more than 80 years ago, prompting new calls for the conservation of its habitat in the far-flung Chilean desert.

Scientists relocated the diminutive Hall's water frog, named for the American researcher and collector Frank Gregory Hall who discovered the species in 1935, in a tiny hot spring oasis near Ollagüe in Chile's Atacama desert.
