Archaeologists found two bird fossils during an excavation in the province of Fujian, in southeastern China . The pieces have an estimated origin of approximately 149 million years in the Jurassic era.
Named Baminornis Zhenghensis, the fossil stood out for presenting different characteristics than scholars had found in the initial evolutionary history of birds.
The study that released the findings was published in the Nature magazine This Wednesday (12).
“Previously, the oldest record of short tail birds is from the lower Cretaceous. Baminornis Zhenghensis is the only Jurassic and the oldest short -tailed bird ever discovered, delaying the appearance of this feature derived from birds by almost 20 million years, ”said Professor Wang, the main author of the study.
The second fossil consists only of a crossbreed – a bone in the shape of the letters V or Y found in the bird’s chest – in a bad state of conservation, allowing archaeologists to only fit it to the Cretaceous bird group.
