Dragon Bird empty threat (generic name: Rahonavi ') is a kind of Dromaeosauridae dinosaurs lived during the Late Cretaceous Campanian northwest of Madagascar, about 83.5 million years ago to 70.6 million years ago. Bird fossils empty threat is a part of the dragon skeleton (No. UA 8656), found in the Mahajanga Province Meifalanuo layer. Etymology Dragon Bird an empty threat called Rahonavi ', rahon' in the Malagasy language means "cloud" or "threat", and avi 'in the "Latin" means "bird", both meaning "from the air threatened birds "; species name ostrom 'is John Oswald Troon Farm (John Ostrom) name. Empty threats will initially be the discoverer of a bird dragon named them Rahon ', but then found that insects have been named a moth families Rahon', then renamed them Rahonavi '. Narrative Dragon is a kind of empty threat of small predators, birds, body close to Archaeopteryx, the second has a sickle-shaped claw toes, similar to the Raptor. Categories Long empty threat classification of birds, many of the historical controversy, in the end they are clade Aves, or similar Dromaeosauridae. Ulna of birds are dry, so that they were originally classified as birds; However, other parts of the skeleton is similar to the typical Dromaeosauridae dinosaurs. Primitive birds and Dromaeosauridae very similar characteristics, and these animals may be repeatedly lost the ability to fly, it is difficult to determine whether the dragon threatened birds, bird empty. Their original narrator that the threat may be empty Bird Long a close relative of Archaeopteryx, it belongs to Aves; threatened birds dragon empty pelvis also shows the evolution of flight adaptation, similar to Archaeopteryx, but it seems to be independently developed. On the other hand, Makovicky and his colleagues think that the dragon is a threat to air the birds of South America Dromaeosauridae half bird and eagle dragon kin, so are half bird subfamily. In 2006, Nuorui Er empty threat and his colleagues also found that the birds are half bird subfamily dragon, so the half-sister bird classification. In 2007, Ailuntena (Alan H. Turner) and his colleagues also found that the dragon threatened birds are half-empty subfamily birds, and close relatives of birds for the semi. Discovery and species Bird fossil dragon empty threat by New York State University and the University of Antananarivo, the excavation team, composed in 1995, Charles Oliver Huber found near the village. Multi-strata in this region covered by dense grass, making the fossils difficult to confirm. After the local fire a hill, a large dragon fossils exposed out of the class. Paleontologists digging the dragon fossils, they found a dragon fossil birds empty threat. Long empty threat of fossil birds represent the natural state, by the hind legs, body, part of the tail, part of the wings, and the shoulder of the composition. Empty body threatened birds than Archaeopteryx dragon about 1 / 5, equivalent to the size of the raven. Close due to lack of relevant fossils, it is difficult to determine the classification of the dragon birds empty threat, the Canadian Museum of Nature of a chest spine, was found in the Kem Kem region of Morocco, dating to the Cretaceous Albian / Cenomanian, close to 100 million years ago to 99 million years ago, is the most similar to the empty threat of fossil birds, dragons, with the larger of the neural tube, but lack of threatened birds, the dragon has space Pleurocoel, should belong to different genera. Although the existence of Pleurocoel with those of different species, different spine, and different individuals may change, but the time and place of the Moroccan fossils show that they are not part of a bird long empty threat.
