90% of sharks mysteriously wiped out nearly 20 million years ago: researchers
Fox News
An extinction event about 19 million years ago decimated shark populations by up to 90%, researchers say.
By studying shark teeth and other marine microfossils buried in deep-sea Pacific sediment, the pair reportedly found that current shark diversity was just a "small remnant of a much larger array of forms" eliminated by the Miocene-era extinction. Sibert told Fox News via email on Saturday that she and Rubin had discovered the event "entirely by accident."More Related News
