Alcione elainus

Alcione is a genus of pterosaur from the Ouled Abdoun Basin of Morocco, dating back to the Maastrichtian stage of the Late Cretaceous period.

The type specimen, FSAC-OB 2, consists of a partial skeleton that preserves various elements, including the femur, humerus, scapulocoracoid, and sternum.

An alternative explanation is that this adaptation was to aid with underwater movement, as shortened wings are present in modern piscivorous birds.

[1] Alcione was discovered in upper Maastrichtian phosphates located in the Ouled Abdoun Basin of Northern Morocco.

[1] A large variety of marine life is known from the region, including sharks and bony fish, in addition to turtles, plesiosaurs, and mosasaurs.

However, in addition to Alcione, more recent studies have revealed at least five more pterosaur species from this location, including Barbaridactylus, Simurghia, and Tethydraco.
