The Archaeopteryx lithographica was believed to be the first bird. It lived in what is now Germany, and was about the size of a raven, weighing 1.8 to 2.2 lbs. It has wings, along with wing feathers that have a similar structure and arrangement to most birds today. Its flat breastbone, which is found in reptiles, indicates that it wasn't a very strong flier. However, its hollow bones and light weight helps it get off the ground more easily. It also has well- developed teeth and three fingers that could move own their own. The A. lithographica has more in common with dinosaurs than birds, so it is now classified as a deinonychosaurs, which is a birdlike dinosaur.
