(är′kē-ŏp′tər-ĭks)
An extinct primitive bird 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 meat-eating dinosaurs. See Note at bird.
