Archaeopteryx airfoil. This would have reduced stall speed by up to 6% and turning radius by up to 12%. The feathers of "Archaeopteryx" were asymmetrical. This has been interpreted as evidence that it was a flyer, because flightless birds tend to have symmetrical feathers. Some scientists, including Thomson and Speakman, have questioned this. They studied more than 70 families of living birds, and found that some flightless types do have a range of asymmetry in their feathers, and that the feathers of "Archaeopteryx" fall into this range. The degree of asymmetry seen in "Archaeopteryx" is more typical for slow flyers than
Archaeopteryx seizing it with its jaws if it was small enough, or with its claws if it was larger. Over the years, twelve body fossil specimens of "Archaeopteryx" and a feather that may belong to it have been found. All of the fossils come from the limestone deposits, quarried for centuries, near Solnhofen, Germany. The initial discovery, a single feather, was unearthed in 1860 or 1861 and described in 1861 by Hermann von Meyer. It is currently located at the Natural History Museum of Berlin. This is generally assigned to "Archaeopteryx" and was the initial holotype, but whether it is a
