An ancient winged shark discovered in Mexico

MEXICO-ALSHARQIYA   March  21 : Paleontologists in Mexico found a fossilized shark from the Cretaceous period, with long pectoral fins, similar to wings, that had not been previously discovered.
Science magazine notes that researchers from France, Germany and Mexico headed by Romain Voula of the French National Center for Scientific Research discovered in 2012 in 93 million-year-old limestone deposits in Vallecilo, Mexico, a complete, strange-shaped, winged shark in good condition.
Scientists have called this type of fish Aquilolamna milarcae, meaning (eagle shark), although it does not at all resemble known sharks, so scientists had to create a special family for it within the order of lemites.

Lamniformes (modern sharks). This fish is distinguished by its length (1.65 meters) and the length of its wing-like pectoral fins (1.90 meters).
Its anatomical features give it a peculiar appearance, combining morphological features of both sharks and rays, and has a long torpedo-like body and tail. They have long, slender pectoral fins, and a wide mouth with very small teeth, which they seem to have used to collect plankton.
The researchers believe that this type of shark was relatively slow-moving, and used its long pectoral fins and tail to slide into the water with an open mouth to collect plankton.
