Dinosaurs, as a scientific topic, encompass a diverse clade of archosaurian reptiles (primarily Dinosauria) that dominated terrestrial ecosystems during most of the Mesozoic Era and are central to research in vertebrate evolution, functional morphology, macroecology, and extinction dynamics. Study of dinosaurs integrates skeletal anatomy, phylogenetics, bone histology, biomechanics, ichnology, and paleoenvironmental reconstruction to investigate growth rates, locomotor strategies, trophic networks, and responses to climatic and tectonic changes. Modern research also emphasizes the dinosaur–bird transition, including the evolution of feathers, flight-related adaptations, and metabolic physiology, as well as patterns of diversification and selectivity associated with the end-Cretaceous mass extinction.
A Smithsonian-led team of researchers have discovered North America's oldest known pterosaur, the winged reptiles that lived alongside dinosaurs and were the first vertebrates to evolve powered flight.
