Pterosaurs comprise an extinct lineage of archosaurs that includes the first vertebrates to develop powered flight and dominated the Mesozoic skies for more than 160 million years. These flying reptiles evolved their anatomy and proportions into well over a hundred known species, achieving the largest sizes and wingspans of any flying animals. For the last several years, pterosaur research is experiencing a high growth of scientific contributions and major advances in our understanding of their palaeobiology are taking place. Application of new research techniques and the fresh discovery of extremely well-preserved specimens (especially from Chinese and Brazilian Konservat-Lagerst├Ątten) allow pterosaur researchers to discuss specific palaeobiological issues, unimaginable just some decades ago. Even though these recent discoveries include significant insights on the brittle pterosaur skeletal remains and even their soft tissue anatomy, controversies on pterosaur research are due to, first and foremost, the research challenges presented by their fragmentary, fragile remains and particularly their uneven fossil record. The goal of this workshop is to discuss several biological issues of this lineage of flying reptiles, with particular focus on their lifestyle and ecological aspects, how they developed their powered flight, bony and soft tissue anatomy, evolution and phylogenetic relationships, as well as morphometric differences within specimens and its relationship with different ontogenetic stages.
