| | Digimorph - Confuciusornis sp. (Chinese fossil avian) |
 | | Confuciusornis, from the early Cretaceous of China, is the oldest known beaked bird, and one of the oldest known birds -- only Archaeopteryx, from the late Jurassic of Germany, is older. |
 | | Confuciusornis is a member of the Confuciusornithidae, the sister-group to the clade composed of Enantiornithes + Ornithurae (includes modern birds). |
 | | This is the case for most fossil birds, because their very delicate bones, many of which are hollow, can only survive the fossilization process in environments producing particularly fine-grained stone. |
