名字的意思： “Fukui wing, the first”1

吃：肉早期鳥類白堊紀早期

Fukuipteryx was a tiny, pigeon‑sized bird that lived in Japan about 120 million years ago. It had a short tail with a special bone called a pygostyle, and its wings were built for flying. This little bird is one of the oldest birds ever found outside of China.1 2

酷東西

趣味知識

Fukuipteryx is one of the most primitive birds known, even more primitive than Jeholornis from China.1

Its skeleton was found in three dimensions, not squashed flat like most other early bird fossils.1 2

The fossil was a young bird, not fully grown, which scientists could tell by looking at its bones under a microscope.1 2

Fukuipteryx had a strong, paddle‑shaped pygostyle at the end of its tail, which helped it steer in the air.1

It lived in a warm, lowland environment with rivers, very different from the volcanic lakes where most early birds are found.2

It lived about 120 million years ago, during the Early Cretaceous period.3 1

?Where was Fukuipteryx found?

It was found in the Kitadani Dinosaur Quarry in Katsuyama, Fukui, Japan.3 1

發現: The first skeleton of Fukuipteryx was collected in 2013 in Katsuyama, Japan. Scientists led by Takuya Imai named it in 2019.1 4
仍有爭議: Scientists are not sure exactly where Fukuipteryx fits on the bird family tree. Some features make it look very primitive, but it also has a pygostyle, which is usually found in more advanced birds.1 2
