Zhengheornis was a tiny bird-like dinosaur that lived about 150 million years ago in what is now China. It had a short tail made of 15 bones, but no pygostyle, which is the fused tailbone modern birds have. This little creature helps scientists understand how bird tails evolved step by step.2 1

Zhengheornis is one of the smallest known early bird relatives, weighing only about as much as a modern robin (74 to 163 grams).2

Its tail had 15 short vertebrae but no pygostyle, showing that tail shortening happened before the bones fused together in bird evolution.2

The name 'buyu' means 'unexpected' in Mandarin, because scientists were surprised by its unusual tail and pelvis.1

Zhengheornis lived alongside other early birds like Fujianvenator and Baminornis in the Zhenghe Fauna of Late Jurassic China.2

Scientists think Zhengheornis was not especially good at climbing trees or walking on the ground, unlike some of its relatives.2

The only known fossil was found in 2024 and includes bones, feather traces, and parts of the arms, legs, and pelvis.1

?How big was Zhengheornis?

Zhengheornis was incredibly tiny, weighing only about 74 to 163 grams, similar to a modern robin. It is one of the smallest known long-tailed early bird relatives.3 4

?When did Zhengheornis live?

Zhengheornis lived during the Early Cretaceous period, about 120 to 130 million years ago, in what is now China.1 3

?Why is Zhengheornis important?

Zhengheornis is important because its short tail of 15 unfused vertebrae shows that tail shortening happened before the bones fused into a pygostyle, filling a gap in bird evolution.3 4

?What did Zhengheornis eat?

Scientists do not know exactly what Zhengheornis ate. It was likely an ecological generalist, not specialized for living in trees or on the ground.3 4
