oilshale Posted March 17, 2017 Share Posted March 17, 2017 A new study led by the American Museum of Natural History (AMNH) provides the strongest evidence to date that sharks arose from a group of bony fishes called Acanthodii (‘spiny sharks’). Analyzing a well-preserved fossil of Doliodus problematicus, a sharklike fish that lived 400-397 million years ago (Devonian period), John Maisey and co-authors identified it as an important transitional species that points to sharks as ancanthodians’ living descendants. http://www.sci-news.com/paleontology/sharks-acanthodians-04706.html 4 Be not ashamed of mistakes and thus make them crimes (Confucius, 551 BC - 479 BC).
