Archaeopteryx reveals hidden mouth features linked to the dawn of avian flight

A Field Museum study of Archaeopteryx fossils uncovers previously unseen skull features—an indicator bone for a highly mobile tongue, soft-tissue traces interpreted as oral papillae on the roof of the mouth, and jaw-tip openings suggesting an early bill-tip organ. These traits, common in living birds but absent in nonflying dinosaurs, may have helped feeding and food processing as flight evolved, implying they appeared around the origin of birds in the Late Jurassic. Archaeopteryx likely represents an early feathered flyer rather than a direct ancestor of modern birds.

Archaeopteryx Skull Yields Earliest Oral Papillae, Shaping Flight Evolution

Scientists unveiled the oldest known oral papillae inside an Archaeopteryx skull, discovered in a 2022 Field Museum fossil using ultraviolet-light preparation. The finding suggests early bird-like dinosaurs already had a specialized mouth-based digestive system to support the high-energy demands of flight, offering new insight into avian evolution and feeding strategies.

"Dinosaur Era Birdwatching: A Quick Guide"

Birdwatching in the age of dinosaurs would have been an extraordinary experience, with ancient birds such as Archaeopteryx, Confuciusornis, Falcatakely, Hesperornis, Vegavis, and Asteriornis roaming the skies. These ancient birds, closely related to dinosaurs, varied in appearance and behavior, from the iconic dino-bird Archaeopteryx with its feathered wings to the aquatic Hesperornis resembling a six-foot-tall penguin. The survival and evolution of these humble birds, including ancestors of modern ducks and chickens, played a crucial role in their ability to endure the mass extinction event that wiped out non-bird dinosaurs.
