Archaeopteryx perhaps, to a cartilaginous sternum. The sideways orientation of the glenoid (shoulder) joint between scapula, coracoid, and humerus—instead of the dorsally angled arrangement found in modern birds—may indicate that "Archaeopteryx" was unable to lift its wings above its back, a requirement for the upstroke found in modern flapping flight. According to a study by Philip Senter in 2006, "Archaeopteryx" was indeed unable to use flapping flight as modern birds do, but it may well have used a downstroke-only flap-assisted gliding technique. "Archaeopteryx" wings were relatively large, which would have resulted in a low stall speed and reduced turning radius. The
Specimens of Archaeopteryx Pohl, who was able to find an anonymous donor willing to offer up the funds. After an initial period of display and scientific study in Germany, the specimen would then be given to the WDC on a long-term loan. After a period of research (Mayr et al. 2005, 2007), the fossil was transferred to the Wyoming Dinosaur Center of Thermopolis, Wyoming, where it has remained since June 2007. The export out of Germany of this specimen—widely considered to be one of the best "Archaeopteryx" fossils known—has caused some concern among German paleontologists and the public. Though no formal legality was
