Does a frog have scaly skin?

For the most part extant amphibians do not have scaly skin, but early amphibians (the ones that ventured onto land first) are thought to have had scaly, fish-like, skin. A possible exception to extant amphibians having scaly skin are those of the Order Gymnophionia and a few anurans which have somatic dermal bone. Amphibians of Gymnophionia are earthworm/snake like amphibians that have not been widely studied.
