Specimens of Archaeopteryx assumed to be imprints of the shafts of primary remiges. Long in a private collection in Switzerland, the Thermopolis Specimen (WDC CSG 100) was discovered in Bavaria and described in 2005 by Mayr, Pohl, and Peters. Donated to the Wyoming Dinosaur Center in Thermopolis, Wyoming, it has the best-preserved head and feet; most of the neck and the lower jaw have not been preserved. The "Thermopolis" specimen was described in the 2 December 2005 "Science" journal article as "A well-preserved "Archaeopteryx" specimen with theropod features"; it shows that the "Archaeopteryx" lacked a reversed toe — a universal feature of birds
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
