Muscular wing-body junction improved Pterosaur flight performance — ScienceDaily

The flying reptiles known as pterosaurs are the closest relatives of dinosaurs and were the first vertebrates to evolve powered flight. However, many details of pterosaur flight anatomy and performance are still unclear. According to a new study led by Dr Michael Pittman — Research Assistant Professor of the Department of Earth Sciences & Vertebrate Palaeontology Laboratory, The University of Hong Kong (HKU); Assistant Dean (e-learning) of HKU Faculty of Science — pterosaurs evolved a muscular wing-body junction to reduce drag and improve flight performance. The findings were recently published in the Proceedings of the National Academy of Sciences (PNAS).

Dr Pittman and colleagues used laser-stimulated fluorescence to image the bones and reveal soft tissues of a Late Jurassic…
