Archaeopteryx following Thomas Henry Huxley's lead in 1868, argued that birds evolved within theropod dinosaurs and "Archaeopteryx" was a critical piece of evidence for this argument; it had several avian features, such as a wishbone, flight feathers, wings, and a partially reversed first toe along with dinosaur and theropod features. For instance, it has a long ascending process of the ankle bone, interdental plates, an obturator process of the ischium, and long chevrons in the tail. In particular, Ostrom found that "Archaeopteryx" was remarkably similar to the theropod family Dromaeosauridae. Specimens of "Archaeopteryx" were most notable for their well-developed flight feathers.
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
