Archaeopteryx or "Allosaurus", which had a crocodile-like anatomy of the brain and inner ear. Newer research shows that while the "Archaeopteryx" brain was more complex than that of more primitive theropods, it had a more generalized brain volume among Maniraptora dinosaurs, even smaller than that of other non-avian dinosaurs in several instances, which indicates the neurological development required for flight was already a common trait in the maniraptoran clade. Recent studies of flight feather barb geometry reveal that modern birds possess a larger barb angle in the trailing vane of the feather, whereas "Archaeopteryx" lacks this large barb angle, indicating potentially
Archaeopteryx It was on display for the first time with six other original fossils of "Archaeopteryx" at the Munich Mineral Show in October 2009. The Daiting Specimen was subsequently named "Archaeopteryx albersdoerferi" by Kundrat et al. (2018). Another fragmentary fossil was found in 2000. It is in private possession and, since 2004, on loan to the Bürgermeister-Müller Museum in Solnhofen, so it is called the Bürgermeister-Müller Specimen; the institute itself officially refers to it as the "Exemplar of the families Ottman & Steil, Solnhofen". As the fragment represents the remains of a single wing of "Archaeopteryx", the popular name of this
