Archaeopteryx brain anatomy was reconstructed using the scan. The reconstruction showed that the regions associated with vision took up nearly one-third of the brain. Other well-developed areas involved hearing and muscle coordination. The skull scan also revealed the structure of its inner ear. The structure more closely resembles that of modern birds than the inner ear of non-avian reptiles. These characteristics taken together suggest that "Archaeopteryx" had the keen sense of hearing, balance, spatial perception, and coordination needed to fly. "Archaeopteryx" had a cerebrum-to-brain-volume ratio 78% of the way to modern birds from the condition of non-coelurosaurian dinosaurs such as "Carcharodontosaurus"
Archaeopteryx be given preference over "lithographica" in instances where scientists considered them to represent the same species. It has been noted that the feather, the first specimen of "Archaeopteryx" described, does not correspond well with the flight-related feathers of "Archaeopteryx". It certainly is a flight feather of a contemporary species, but its size and proportions indicate that it may belong to another, smaller species of feathered theropod, of which only this feather is known so far. As the feather had been designated the type specimen, the name "Archaeopteryx" should then no longer be applied to the skeletons, thus creating significant nomenclatorial
