Archaeopteryx. Artwork of the prehistoric feathered reptile Archaeopteryx which lived around 150 million years ago. Discovered in 1861 in southern Germany, it was the first feathered fossil specimen ever found. Despite possessing bird-like feathers, wings and a wishbone, Archaeopteryx also had sharp teeth, finger digits and a bony tail similar to non-bird predatory dinosaurs. This species and numerous other feathered fossils support the theory that modern day birds evolved from prehistoric theropod dinosaurs.
