Fedexia striegeli was a member of an extinct amphibian group called trematopids, which lived in the tropical Pittsburgh climate almost 305 million years ago.
Fedexia striegeli was discovered near the Pittsburgh International Airport in 2004 by a geology student. It was then identified by Carnegie Museum staff as a new species.
This fossil provided scientists with important clues that helped them understand more about prehistoric climate change and amphibian evolution. It showed that amphibians began spending more time on land about 305 million years ago — 20 million years earlier than scientists had previously thought!
