The word 'pterosaur' is derived from the Greek words 'pteron', meaning 'wing', and 'sauros', meaning 'lizard'. The term was first coined in the 19th century to describe these distinct flying reptiles that lived during the Mesozoic era. Pterosaurs first appeared in the late Triassic period and thrived until the end of the Cretaceous period. They exhibited various forms of flight adaptations and were an essential part of the Mesozoic ecosystem, distinguished by their unique skeletal structures, including a specialized elongated fourth finger that supported their wing membranes. The study of pterosaurs has greatly advanced with the discovery of numerous fossils, providing insight into their diversity, behavior, and evolutionary relationship to other archosaurs.
