Researchers have described a new carnivorous amphibian from western Pennsylvania. The 300-million-year-old remarkably preserved fossil is one of few amphibians displaying evidence of a land-based life history so early in time. The rocks where Fedexia was found are nearly 20 million years older than those of its fossil relatives, suggesting that the group's expansion occurred much earlier than previously thought.
