Amassive shark die-off 19 million years ago that was reported in the prestigious journal Science and made headlines the world over did not actually happen, according to new research.In June, two U.S. scientists reported a decline in shark diversity with a decrease of more than 90 percent in the abundance of deep-ocean sharks all those years ago.
However, researchers at the Natural History Museum Vienna and others have now cast doubt on the event, saying it probably did not happen.The Austrian researchers say that due to the relative stability of the deep sea, such an enormous decline in deep-ocean sharks would be surprising.In several projects financed by the Austrian Science Fund (FWF), we examined marine deposits of the same age in Italy, Greece, Turkey, Tanzania, India, Sri Lanka and Oman. Nowhere was there any evidence of an extinction event 19 million years ago," Mathias Harzhauser, who heads the museum's Geology and Paleontology Department, said in a statement.
