Oldest oceanic reptile ecosystem from the Age of Dinosaurs found on Arctic island

More than 30,000 teeth, bones and other fossils from a 249 million-year-old community of extinct marine reptiles, amphibians, bony fish and sharks have been discovered on the remote Arctic island of Spitsbergen. These record the earliest radiation of land-living animals into oceanic ecosystems following cataclysmic extinction and extreme global warming at the dawn of the Age of Dinosaurs.
