Scientists discovered two Jurassic bird fossils in China, pushing back bird diversification by 20 million years. One, ...

It had feathers and wings, so it was clearly a bird — but it sported a long tail and sharp claws, which seemed reptilian. A smattering of other feathery Jurassic fossils, including those known ...

Jurassic bird fossil discovery of a species named Baminornis zhenghensis pushes bird evolution timeline back 20 million years.

Scientists uncovered a 149-million-year-old bird fossil in southeastern China with unexpectedly modern traits they believe could rewrite the evolutionary history of birds.

Biologists previously believed modern birds had evolved 20 million years later than the new evidence suggests.

Birds are breathing in high levels of airborne microplastics into their lungs—and, likely, so are we, with unclear effects on ...

It is not easy to see in natural conditions the Bird of the Year 2025 in Belarus – the black-tailed godwit – but the Belovezhskaya ...

While this species is sometimes described as the first bird, other scientists would describe it as bird-like. Archaeopteryx’s long, bony tail is one of the features that show it comes very early in ...

Bird — or birdlike — fossils from the Jurassic period are relatively rare and often incomplete. Despite Archaeopteryx’s feathered wings, it closely resembled non-avialan dinosaurs, notably due to its ...

When vertebrates moved onto land, long ago, some of them eventually became airborne, way after the insects did. There are three groups of vertebrates that have used powered, muscle-driven flight: ...

The early evolution of birds has long been a mystery due to the limited ... Most remarkably, Baminornis had a short tail ending in a pygostyle – a fused bone also found in modern birds.
