Archaeopteryx They were markedly asymmetrical and showed the structure of flight feathers in modern birds, with vanes given stability by a barb-barbule-barbicel arrangement. The tail feathers were less asymmetrical, again in line with the situation in modern birds and also had firm vanes. The thumb did not yet bear a separately movable tuft of stiff feathers. The body plumage of "Archaeopteryx" is less well documented and has only been properly researched in the well-preserved Berlin specimen. Thus, as more than one species seems to be involved, the research into the Berlin specimen's feathers does not necessarily hold true for the rest
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
