archaeopteryx
(är’kē-ŏp’tər-ĭks)
An extinct primitive bird of the genus Archaeopteryx of the Jurassic Period, having characteristics of both birds and dinosaurs. Like dinosaurs, it had a long, bony tail, claws at the end of its fingers, and teeth. Like birds it had wings and feathers. Many scientists regard it as evidence that birds evolved from small carnivorous dinosaurs. See Note at bird.
