Not Your Average Pterosaur

The fossil of a juvenile, late-Jurassic flying reptile has been ignored for the past decade because it appeared to be another of the estimated 120 specimens of the genus Rhamphorhynchus found at the Solnhofen limestone beds in Germany. The reptile is a Pterosaur, which is a flying reptile that resemble dinosaurs, but they are not. More in depth research was done by David Hone of the University of Bristol in England and his colleagues, which resulted in new information pertaining to the 14 centimeter flying reptile. They found that the reptile had fewer teeth and a more flexible tail than other Rhamphorhynchus species that it was once categorized with. Also, the reptile's outermost bone of each wing curves outward, different than any other flying vertabrate, alive or extinct. "The opposite curving wing bones could have made flying harder, but somewhat improved maneuverability for the small reptile", noted David Hone. The researchers are creating a genus called, Bellubrunnus, for this non-average flyer. The fossil pictured is under UV light, which makes it a lot easier to see because the fossil bones are the same color as the rock.
