Archaeopteryx suggested that "Archaeopteryx" was a dinosaur that was no more closely related to birds than were other dinosaur groups. Kurzanov (1987) suggested that "Avimimus" was more likely to be the ancestor of all birds than "Archaeopteryx". Barsbold (1983) and Zweers and Van den Berge (1997) noted that many maniraptoran lineages are extremely birdlike, and they suggested that different groups of birds may have descended from different dinosaur ancestors. The discovery of the closely related "Xiaotingia" in 2011 led to new phylogenetic analyses that suggested that "Archaeopteryx" is a deinonychosaur rather than an avialan, and therefore, not a "bird" under most
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
