Abstract: High-resolution computed tomography is used to compare cranial volumes of extant birds, the early avialan Archaeopteryx lithographica, and non-avian maniraptoran dinosaurs that are close to the origins of Avialae and avian flight; the cranial cavity of Archaeopteryx is not distinct from that of maniraptorans, suggesting that some non-avian maniraptorans may have had the neurological equipment required for flight.
