The newly identified species lived more than 120 million years ago and carried a feature that immediately caught researchers' attention.Its body was relatively small, but its tail feathers were anything but.
Researchers described the species in a study published in PLOS One and say it offers another clue in the ongoing effort to understand how feathers evolved, as per a report by Gizmodo.What immediately set the bird apart were its extraordinary tail feathers.
The bird itself measured only about six inches from beak to tail, yet two slender tail feathers stretched to roughly 12 inches in length.
Clark discovered the specimen while examining hundreds of bird fossils housed at China’s Shandong Tianyu Museum.
According to a statement from the Field Museum, the fossil immediately stood out because of its unusual tail, as per a report by Gizmodo.“I saw this little guy, and I did a double-take when I saw the tail feathers,” Clark recalled.

A remarkable fossil discovery in China is giving scientists a fresh look at how some of the earliest birds may have used feathers to stand out from the crowd. The newly identified species lived more than 120 million years ago and carried a feature that immediately caught researchers' attention.Its body was relatively small, but its tail feathers were anything but. The unusual bird appears to have sported an extravagant display that may have helped it attract mates, much like some modern birds do today.The fossil, discovered in Liaoning, China, dates back approximately 121 million years to the Cretaceous period. Researchers described the species in a study published in PLOS One and say it offers another clue in the ongoing effort to understand how feathers evolved, as per a report by Gizmodo.What immediately set the bird apart were its extraordinary tail feathers. The bird itself measured only about six inches from beak to tail, yet two slender tail feathers stretched to roughly 12 inches in length. According to researchers, those feathers were likely ornamental rather than practical.“The first thing we did was to determine if this specimen was indeed a new species—and it was,” Alex Clark, the study’s lead author and a PhD student at the University of Chicago, said in an interview with PLOS.“121 million years ago, this male Plumadraco was dragging along a train of tail feathers twice its body length, just to impress potential mates—something we see today in modern birds as well. Pretty cool, if you ask me!”Like many important fossil finds, this one was hiding in plain sight. Clark discovered the specimen while examining hundreds of bird fossils housed at China’s Shandong Tianyu Museum. According to a statement from the Field Museum, the fossil immediately stood out because of its unusual tail, as per a report by Gizmodo.“I saw this little guy, and I did a double-take when I saw the tail feathers,” Clark recalled. “I’m really interested in the way birds do displays to attract mates, and I thought that these tail feathers were so crazy, they had to be used for something like that.”Researchers photographed the specimen in detail and used digital analysis to study its features more closely. The fossil was exceptionally well preserved, including feathers extending from the head down to the ankles, wing feathers, and the remarkable tail plumes.Clark noted that the specimen represents a “new record” for any enantiornithine, a group that was among the most diverse birds of the Mesozoic Era.Although scientists cannot determine every detail from the fossil, they believe the feathers were likely used during courtship displays.The structure of the tail suggests it would have created striking movement when raised or lowered, similar to display behaviors seen in some living birds today.“Additionally, other enantiornithine specimens suggest muscles along the pelvis and tail, which raise and lower the tail,” Clark explained in the PLOS interview. “With this specimen, we have a pretty strong argument that not only did probable males try to attract females with feather ornamentation, but they also did so with ridiculous lengths and probably displays.”While researchers acknowledge that paleontology often involves informed hypotheses, the discovery offers evidence that elaborate feather displays may have existed for a very long time, as per a report by Gizmodo.“Based on these fossils, female choice in selecting ornamented males has been playing a huge part in how birds look and behave for more than 120 million years,” Clark said in the Field Museum statement.The discovery of Plumadraco bankoorum provides another fascinating glimpse into the ancient origins of bird behavior and highlights how eye-catching displays may have been shaping evolution since the age of dinosaurs.A: It has been named Plumadraco bankoorum, meaning “Banko’s feather dragon.”A: The feathers measured about 12 inches, nearly twice the bird’s body length.
