Longipteryx

Igama lithetha: “long wing”1

Yayitya: IzityaloIintaka zokuqalaiCretaceous yokuqala

Longipteryx was a tiny bird that lived about 120 million years ago in what is now China. It had long, strong wings and a very long snout with hooked teeth at the tip. This little bird was a great flyer and could perch on branches like modern birds.1 2

izinto ezimnandi

Iinyani ezimnandi

Longipteryx had a very long snout that was longer than the rest of its head, with a few hooked teeth at the tip.1

Its wings were much longer than its legs, with the upper arm bone (humerus) being 1.56 times the length of the thigh bone (femur).1

Unlike most other early birds, Longipteryx had uncinate processes on its ribs, which helped strengthen its ribcage and improve breathing.1 2

Its feet were built for perching, with all four toe bones (metatarsals) ending at nearly the same level, just like modern perching birds.2

Scientists once thought Longipteryx ate fish or insects, but in 2024 a study found it actually ate seeds and fruits.1

Longipteryx had a big breastbone with a well-developed keel, which gave it powerful flight muscles.2

Umfanekiso owenziwe yi-AI: Longipteryx — Umfanekiso owenziwe yi-AI obonisa indlela Longipteryx esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

ubuzile

Eyona mibuzo ibuzwa kakhulu: Longipteryx

?How big was Longipteryx?

Longipteryx was very small, with a wingspan of about 46.3 cm (1.52 ft) and a body mass of about 193 g (6.8 oz).1

?What did Longipteryx eat?

Longipteryx ate fish. A 2024 study found fish remains in its stomach, showing it was a piscivore.1 3

?Did Longipteryx have feathers?

Yes, Longipteryx had feathers. The holotype preserves body feathers, wing coverts and down, but no long tail feathers.1

?Could Longipteryx fly?

Yes, Longipteryx was a good flyer. It had long, strong wings and a well-developed breastbone with a keel for powerful flight muscles.1

Inyaniso ngeentsomi

Intsomi: Longipteryx was a fish-eater because of its long snout and teeth.

Inyaniso: Scientists now know from fossil evidence that Longipteryx ate seeds and fruits, not fish.1

Ukufunyanwa: Longipteryx was named in 2000 by Zhang Fucheng and colleagues from a nearly complete skeleton found in the Jiufotang Formation in Chaoyang, China.4 2
Kusaxoxwa ngayo: Scientists are not sure whether Longipteryx used its long snout and teeth to catch prey or for some other purpose.1
