Archaeopteryx
Archaeopteryx is a Late Jurassic feathered theropod from the Solnhofen Limestone of Bavaria, Germany, long regarded as a pivotal transitional fossil linking non-avian dinosaurs and birds. Known from exquisitely preserved specimens with flight feathers, teeth, and a long bony tail, it has been central to research on the origin of avian flight and the early evolution of the avian body plan.
