The fossil shark flew under the water like a ray

Early in the Cretaceous period, some wide-winged sharks flew underwater, like large rays today. This was surprising to experts who previously suspected that this type of underwater excursion did not occur until much later, when the ancestors of the day’s rays specialized in it. However, a team of European and Mexican paleontologists have now discovered the “eagle shark” fossil that was able to sail underwater with fins that were more than 93 million years long.
