121-Million-Year-Old 'Feather Dragon' Bird Found
4 Jun
Summary
- A new prehistoric bird species, Plumadraco bankoorum, was identified from a 121-million-year-old fossil.
- This ancient bird possessed tail feathers twice its body length, likely for display.
- The fossil was discovered in northeastern China's Jehol deposits, indicating a forested wetland habitat.
A remarkable 121-million-year-old fossil has revealed a new species of prehistoric bird, named Plumadraco bankoorum. This extinct creature, roughly the size of a robin, is distinguished by its proportionally enormous tail feathers, extending twice the length of its body. These unique, rachis-dominated feathers (RDFs) with racket-shaped tips suggest a primary role in visual displays for mating or communication, rather than aiding in flight. The fossil originates from the Jehol deposits in northeastern China, an area characterized by forested wetlands and a temperate climate.
Although parts of the fossil are poorly preserved, the exceptional condition of its tail feathers has allowed for detailed scientific examination. Researchers hypothesize that the exaggerated tail served to increase breeding success, indicating that female mate choice may have significantly influenced the evolution of avian appearance even in the Cretaceous period. The species name, Plumadraco bankoorum, translates to 'feather dragon,' reflecting its striking tail. This discovery underscores the ancient origins of elaborate tail feather displays in birds.
