Jeholopterus

名字的意思： “Jehol wing”1

吃：昆蟲飛行爬蟲類侏羅紀中期嚴格來說不是恐龍

Jeholopterus was a small flying reptile that lived in what is now China. It had a very short, wide skull like a frog and its wings were attached to its ankles. Scientists think it ate insects and maybe even small fish.2 1

趣味小知識：翼龍在恐龍頭上飛來飛去，但牠們是恐龍的親戚，不是恐龍喔。

趣味知識

Jeholopterus is one of the most complete anurognathid pterosaurs ever found, with its wing membranes and hair-like fibers preserved as fossils.2

Its skull was wider than it was long, giving it a frog-like face.2

The wing membrane attached to the ankle, and its feet were webbed, which may have helped it swim or walk on soft ground.2

Jeholopterus had a wingspan of about 90 centimeters (3 feet), making it a small to medium-sized pterosaur.2 1

The fossil was found in the Daohugou Beds of Inner Mongolia, which are about 165 to 160 million years old, from the Middle to Late Jurassic.1

Its wing claws were extremely long, about one and a half times the length of its foot claws.2

The hair-like fibers on its body are called pycnofibers, and they are not the same as mammalian hair.2

關於 Jeholopterus 最常被問的問題

?Was Jeholopterus a dinosaur?

No, Jeholopterus was a pterosaur, a flying reptile that is closely related to dinosaurs but not a dinosaur itself.1 3

?How big was Jeholopterus?

Jeholopterus had a wingspan of about 90 centimeters (35 inches), which is about the size of a Mallard Duck.1 3

?What did Jeholopterus eat?

Scientists think Jeholopterus mostly ate insects, but its longer, curved teeth suggest it might also have eaten small fish.1 4

?Did Jeholopterus have feathers?

No, Jeholopterus did not have feathers. It was covered in hair-like fibers called pycnofibers, which are different from mammalian hair.1 3

?Could Jeholopterus swim?

It might have been able to swim. Its feet were webbed and the wing membrane attached to the ankle, which could have helped it move in water.1 4

?When did Jeholopterus live?

Jeholopterus lived during the Middle to Late Jurassic period, about 168 to 160 million years ago.1 5
