A new scientific development has been in talks with scientists discovering a new species of ancient winged shark, which fed on plankton eons before the emergence of giant manta rays.
According to new research published in the journal Science, the ancient winged shark, nicknamed the 'eagle shark', is the second known plankton-eating fish discovered from the last epoch when dinosaurs still ruled the earth.
Eagle shark, Aquilolamna millrace, lived around 93 million years ago during the Cretaceous Period and its fossil was discovered in the northeast of Mexico.
The specimen of the eagle shark had unusual proportions, a fin span of about 1.9 meters and a length from head to tail of about 1.65 meters, however, this left the scientists amazed.
Until this discovery, scientists had only known of one category of large plankton feeders in the Cretaceous period, a group of large bony fish known as pachycormidae.
