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 first time with six other original fossils of "Archaeopteryx" at the "Munich Mineral Show" in October 2009. A first, quick look by scientists indicates that this specimen might represent a new species of "Archaeopteryx". It was found in a limestone bed that was a few hundred thousand years younger than the other finds. The eighth specimen of "Archaeopteryx" was officially announced in February 1996 at a special exhibition at Bavaria’s Naturkunde Museum. Its director, Matthias Mäuser, made the announcement to a surprised audience that the specimen had already been casted and that this was on display in the exhibit. Few
