Fish Permian twin Fossil Palaeoniscus freislebenensis 30cm x 12 cm approx 1.5kg Durham, North East England
Fish Fossils are found in fresh and sea water. There are two main groups, Chondrichthyes (cartilaginous) such as rays and sharks which do not fossilize well (however, their teeth are commonly found) and Actinopterygii (bony fish) which do fossilize well. Both groups date back to the Palaeozoic period - 544 to 245 million years ago.
