Enantiornithines Guide, Meaning , Facts, Information and Description
The Enantiornithines are an extinct group of flying birds from the Cretaceous. Recently, palaeontologists in China found a Enantiornithin fossil with flight feathers on its legs as well as its arms, linking it with the four-winged dinosaur Microraptor. This may suggest that some early birds had four wings, not two.
