Newly analyzed fossil reveals earliest feathered flight

Archaeopteryx is the fossil that proved Darwin right. It's the oldest known fossil bird, and it helps show that all birds— including the ones alive today—are dinosaurs. And while the first Archaeopteryx fossil was found more than 160 years ago,
A 166-million-year-old Middle Jurassic herbivorous dinosaur, the size of a large dog and bipedal, has been discovered on the Isle of Skye.

ScienceAlert on MSNIncredible Detail on This Archaeopteryx Fossil Could Help Settle Flight DebateBased on what we know of living birds with long wings, the role of tertial feathers is primarily to close the wing gap and aid in flight, but the unusual fan-shape found on the Chicago Archaeopteryx fossil suggests these feathers may have also played a role in visual communication. The two hypotheses are not mutually exclusive.
Significantly, the Chicago specimen is the first known Archaeopteryx fossil to preserve tertials — the flight feathers closest to the body. These feathers, not previously seen in non-avian feathered dinosaurs, may represent a flight-related innovation and an important evolutionary step toward powered flight.
