Cryptovolans pauli is a 90 cm long feathereddromaeosauriddinosaur recently discovered in the Jiufotang site, China. Its species name honours paleontologistGregory S. Paul. Cryptovolans is related to Velociraptor. Sinornithosaurus by Jim Robins Feathered dinosaurs are regarded by many paleontologists as the missing link between birds and dinosaurs — but this view is probably too simplistic. ...

Binomial name Velociraptor mongoliensis Osborn, 1924 Velociraptor mongoliensis (fast thief), was an agile and slender theropod dinosaur species from the Upper Cretaceous (Campanian) with an up-curved skull and large sickle-shaped claws. ...
Flight capability
Cryptovolans is remarkable for being the first known dinosaur to have flight-capable feathers on its legs as well as on its arms. It also had feathers on the end of its long tail, and probably on the rest of its body.
It is believed that Cryptovolans may have been able to fly better than Archaeopteryx, the animal usually referred to as the earliest known bird. Possessing a keel and ribs with an uncinate process, Cryptovolans has modern bird features which are absent in Archaeopteryx. The fact that this flight-capable animal is also very clearly a dromaeosaurid suggests that the Dromaeosauridae might actually be a basal bird group, and that later (larger) species such as Deinonychus were actually secondarily flightless. Current evidence for this theory is inconclusive, and some of the modern bird-like features in Crytovolans may have evolved independently. Regardless of whether dromaeosaurs are a sister group to birds or actual members of Aves, both groups are part of the Maniraptora suborder and are ultimately theropod dinosaurs. Binomial name Archaeopteryx lithographica Meyer, 1861 Archaeopteryx lithographica is widely accepted as the earliest and most primitive known bird. ... Binomial name Deinonychus antirrhopus Ostrom, 1969 Deinonychus antirrhopus (counterbalancing fearsome claw) is a wolf-sized, carnivorous dromaeosaurid dinosaur species from the Early Cretaceous Clovery Formation of Montana. ... For other meanings of bird, see bird (disambiguation). ... Maniraptora is a group used in biological classification to cover the birds and the dinosaurs that were related to them. ... Families See text Theropods (beast foot) are a group of bipedal, primarily carnivorous dinosaurs, belonging to the saurischian (lizard-hip) family. ...
Many think that Cryptovolans is a junior synonym of Microraptor. Microraptor was a small, bird-like dinosaur related to the dromaeosaurs. ...
Cryptovolans pauli was a small theropoddinosaur that was about 3 feet long.
Cryptovolans is characterized by the presence of primary flight feathers as being a bird.
Since Cryptovolans was a dromaeosaur capable of flight, this is a strong indication that larger dromaeosaurs, such as Deinonychus and Velociraptor, were secondarily flightless as speculated by Greg Paul (1988, 2002).
