Archaeopteryx compared to its body length. It could reach up to in body length, with an estimated mass of . "Archaeopteryx" feathers, although less documented than its other features, were very similar in structure to modern-day bird feathers. Despite the presence of numerous avian features, "Archaeopteryx" had many non-avian theropod dinosaur characteristics. Unlike modern birds, "Archaeopteryx" had small teeth, as well as a long bony tail, features which "Archaeopteryx" shared with other dinosaurs of the time. Because it displays features common to both birds and non-avian dinosaurs, "Archaeopteryx" has often been considered a link between them. In the 1970s, John Ostrom,
Granger Archaeopteryx Granger Archaeopteryx The Granger Archaeopteryx is a British single-engined, tailless parasol monoplane designed and built in the late 1920s by two brothers, R.F.T. and R.J.T. Granger. The sole example built is currently under restoration for flight. The layout of the Archaeopteryx was inspired by the tailless swept-winged Westland-Hill Pterodactyl, itself derived from the aircraft of J. W. Dunne. These aircraft had been designed to resist stalling and to allow easy and safe recovery if they did. The Archaeopteryx follows the Dunne D.7 in being a parasol wing monoplane, however it differs in being the first aircraft of tailless swept configuration
