WELL, CLOSING ONE of them anyway. From the Telegraph, a missing link of sorts is located:

The origin of today’s amphibians is controversial because of a lack of intermediate forms to show which ancient creatures evolved into frogs and salamanders.

Now a Texan fossil, Gerobatrachus hottoni (“Hotton’s elder frog”) from around 300 million years ago, proves the previously disputed fact that some modern amphibians, frogs and salamanders evolved from one group of ancient primitive amphibians called temnospondyls, some of which were up to 1.5 metres long.

More.

Just a matter of time before creationists point out that two new gaps are now opened up, on either side of G. hottoni, but there you go.
