酷東西

趣味知識

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

迷思破解王

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

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