Fujianvenator is an anchiornithid avialan from the Late Jurassic of China, whose discovery gave important insight to the evolution of birds. It had proportionately long legs, with the tibia twice the length of the femur. This suggests it may have been a strong runner, and possibly had a terrestrial or wading lifestyle. Fujianvenator was a small dinosaur, weighing about 640 g. As an avialan, it was almost certainly covered in feathers, though it does not seem likely to have been capable of flight.

Norellraptor is a microraptorian dinosaur known from a specimen with exceptionally well-preserved feathers. Its discovery supports evidence that gliding and flight-related traits evolved independently in multiple dinosaur groups. Norellraptor had long feathers on its arms and legs, typical of microraptorians, resulting in a four-winged body plan.

Cast of a Scaphognathus crassirostris, a kind of pterosaur. On display as part of the exhibit "Pterosaurs: Flight in the Age of Dinosaurs" at the Cleveland Natural History Museum in Cleveland, Ohio, in the United States. This animal lived about 150 million years ago. This fossil was found in the Solnhofen formation in Germany. This is a cast; the fossil itself is held by the Institute of Geology and Paleontology at the University of Bonn.

Baminornis is the oldest known bird with a fused pygostyle, a skeletal feature that implies tail feathers. Its discovery pushed back current understanding of bird evolution and global distribution by 20 million years. Baminornis was about 15 cm in length, had many features in common with modern birds, including the capability for powered flight.
