Christian Erich Hermann von Meyer described one of the initial discoveries of a fossil of this animal, and its first skeleton was found near Langenaltheim, Germany before being given to Karl Häberlein.  This species features a notable hyperextendable second toe, sometimes referred to as a "killing toe" and John Ostrom found that this species was similar to the family Dromaeosauridae.  The least complete skeleton of this animal is currently located at the Teylers Museum, and the most complete specimen of this animal was discovered by Jakob Niemeyer before being traded for a cow.  The Haarlem and Berlin Specimens are examples of, for 10 points, what animal, whose fossils were found in the limestone deposits of Solhnofen, Germany, a primitive species of bird?
