New fossil study illuminates on the evolutionary success of frogs

University College Cork
Peer-Reviewed Publication

A new study lead by UCC palaeontologists discovered that frogs have conserved their ecology in the last 45 million years. Dr Daniel Falk, together with colleagues from UCC, Germany and the United States, studied 45-million-year-old frogs from the Geiseltal fossil site in central Germany. Remarkably, the fossils preserve skin remnants and layers of microscopic fossilised cell structures called melanosomes.
