The debate in paleontology over how good the "flying reptiles" (pterosaurs) were at actual flying has been long-running and sometimes fierce. New analysis of a well-preserved specimen from China indicates that networks of unique fibers in the animals' wings gave them the kind of precise control birds have today.
COMMENT: I doubt this one find will settle things. Even if the early species in this study was a good flier, were later and larger (including some MUCH larger) pterosaurs equally capable, or were some mainly gliders? Either way, pterosaurs will maintain their hold on the human imagination. Flying vertebrates the size of aircraft have a way of doing that.
