The Frogamander

Yahoo News is reporting the discovery of a fossil critter that links salamanders with modern frogs. Quoth the article:

Modern amphibians -- frogs, salamanders and earthworm-like caecilians -- have been a bit slippery about divulging their evolutionary ancestry. Gaps in the fossil record showing the transformation of one form into another have led to a lot of scientific debate.

The fossil Gerobatrachus hottoni or elderly frog, described in the journal Nature, may help set the record straight.

"It's a missing link that falls right between where the fossil record of the extinct form and the fossil record for the modern form begins," said Jason Anderson of the University of Calgary, who led the study. "It's a perfect little frogamander," he said.

Another nail in the coffin.
