Anurognathus

名字的意思： “frog jaw”1

吃：昆蟲飛行爬蟲類侏羅紀晚期嚴格來說不是恐龍

Anurognathus was a tiny pterosaur that lived in the Late Jurassic. It had a very short, wide head and big eyes, like a little flying frog. It probably hunted insects at dusk.1 2

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。

酷東西

趣味知識

Anurognathus had a very short tail, unlike most early pterosaurs. This made it more maneuverable when hunting insects.1

Its skull was wider than it was long, and its eyes were huge. This helped it see well in dim light.1 2

Anurognathus weighed only about 40 grams (1.4 ounces), as light as a small bird.1

Its wings were short and broad, and it could probably fly slowly and twist through tight spaces.1 2

Scientists think Anurognathus had bristles around its mouth, like a fringe, to help catch insects.1 2

Only two fossils of Anurognathus have been found, both in Germany. One is a juvenile.1

關於 Anurognathus 最常被問的問題

?How big was Anurognathus?

Anurognathus was tiny, with a wingspan of about 35 cm (14 in) and a weight of only 40 grams (1.4 oz), as light as a small bird.1

?What did Anurognathus eat?

It ate insects. Its pin-like teeth and small mouth were perfect for catching tiny bugs about 11 mm long.1

?Could Anurognathus fly?

Yes, it was a pterosaur and could fly. It had short, broad wings and probably flew slowly and maneuvered well to catch insects at dusk.1

?Did Anurognathus have feathers?

No, it did not have feathers. It had a fuzzy coat of hair-like fibers called pycnofibers, and possibly bristles around its mouth.1

?When did Anurognathus live?

Anurognathus lived during the Late Jurassic period, about 150 to 148 million years ago.1

?Why did Anurognathus have big eyes?

Its huge eyes helped it see well in dim light, so it could hunt insects at dusk or in the dark.1

?Is Anurognathus a dinosaur?

No, Anurognathus is a pterosaur, a flying reptile that is not a dinosaur.1

?How many fossils of Anurognathus have been found?

Only two fossils have been found, both in Germany. One is a juvenile, and the other is a subadult.1
