Aurornis. Artwork of the prehistoric feathered reptile Aurornis which lived around 160 million years ago. Discovered in 2013 in China, it is considered the oldest known example of a bird-like dinosaur. Despite possessing feathers, wings and a wishbone, Aurornis also had sharp teeth, forelimb digits and a bony tail similar to non-bird predatory dinosaurs. It was not capable of powered flight but may have been able to glide. This species and numerous other feathered fossils support the theory that modern day birds evolved from prehistoric theropod dinosaurs.
