Unveiling the Secrets of Archaeopteryx's Flight Ability: New Discoveries Revisited
A recently discovered finding suggests that the Archaeopteryx, an extinct bird-like reptile, may have possessed the ability to fly.
The age-old debate about Archaeopteryx, a bird estimated to have lived 150 million years ago, and its flying capabilities has recently gained fresh momentum. A recent study published in "Nature" by a team from the USA has added more ammunition to the argument that Archaeopteryx had the ability to fly.
The research team focused on the smallest and best-preserved Archaeopteryx specimen, which was recently acquired by the Field Museum in Chicago. After careful examination, the specimen revealed some intriguing details.
To peek inside the Archaeopteryx’s secrets, the researchers used cutting-edge technology like micro-computed tomography with UV light to make soft tissues visible. This revelation marked the first time that the primitive bird was found to have tertiary feathers as well, much like modern birds. These fan-shaped feathers provide extra coverage and help maintain the aerodynamic surface necessary for lift generation during flight.
The Long and the Short of It
Jingmai O'Connor, the lead author, explained that Archaeopteryx had a considerably longer upper arm bone compared to most living birds. This arrangement might have led to a gap between the primary and secondary wing feathers and the rest of the body, leading to disrupted lift and potentially preventing flight.
Enter the tertiary feathers that Georgia Archaeopteryx sported. These filled the gap between the wings and the body, thus improving flight stability and efficiency. This feature is rarely found in non-avian dinosaurs, and it's especially absent in feathered dinosaurs that are closely related to birds but aren't counted as birds themselves. Instead, these dinosaurs possess wing feathers ending at the elbow.
Communication Over Confirmation?
Researchers suspect that Archaeopteryx's large expansive feathers may have served some purpose beyond flight, possibly in visual communication. As fascinating as its wings were, evidence from the specimen's extremities indicates that Archaeopteryx also spent considerable time on the ground and may have even climbed trees, much like pigeons today.
Interestingly, the little finger on the bird's hand was found to be movable. Additionally, the tail was longer than anticipated, with 24 tail vertebrae compared to the previously known 22.
Could These Be Clues to Archaeopteryx's Flight?
The evidence suggests that Archaeopteryx did indeed possess the ability to fly, although it may not have been as effective as modern birds. Its advanced flight feathers, the presence of tertiary feathers, longer upper arm bone, movable little finger, and longer tail all support this notion.
In an exciting development for the world of avian evolution, this study continues to shed light on the lives and abilities of our ancestors, offering fascinating insights into the evolutionary path that led to the birds we know today.

The study's findings, published in "Nature," suggest that science, particularly environmental-science and technology, have greatly contributed to our understanding of Archaeopteryx's flight ability. The researchers discovered that this ancient bird possessed tertiary feathers, a feature rarely observed in non-avian dinosaurs, which improved flight stability and efficiency in the environment.
Moreover, the study delves into possible non-flight functions of Archaeopteryx's large feathers, with a hypothesis that they could have served a role in visual communication, hinting at the interplay between science and space-and-astronomy, as understanding these feathers may provide insight into the animal kingdom's communication methods, contributing to the community policy's goals of fostering knowledge and learning.
