名字的意思： “hairy devil”1

吃：魚飛行爬蟲類侏羅紀晚期嚴格來說不是恐龍

Sordes was a small flying reptile that lived about 155 million years ago. It had furry, hair-like coverings on its body and wings, making it look a bit like a tiny dragon. It was not a dinosaur, but a pterosaur, a close cousin of dinosaurs.1 3

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

Sordes was the first pterosaur to show clear evidence of hair-like filaments, called pycnofibres, covering its body. This was a big clue that pterosaurs were warm-blooded.1

Its wings were relatively short, and it had a long tail that made up more than half its total length. The tail ended in a diamond-shaped vane.1

The skull of Sordes was about 8 cm (3.2 inches) long, and it had no head crest, unlike many other pterosaurs.1

The wing membrane of Sordes was attached to its legs, and there was also a membrane between its legs, which helped with flying and gliding.1

Scientists found two types of pycnofibres on Sordes: longer ones at the edge of the wing membrane and shorter ones near the body.1 2

Sordes lived during the Late Jurassic period, about 155 million years ago, in what is now Kazakhstan.1 3

關於 Sordes 最常被問的問題

?What did Sordes eat?

It likely ate insects or amphibians. Its front teeth were good for catching slippery prey, and its back teeth were for crushing.1

?How big was Sordes?

About 0.63 metres across the wings, and its skull was only 8 cm long.1

?Why is it called Sordes?

Its name means 'hairy devil' in Latin. 'Sordes' means 'filth' or 'scum', but the scientist who named it intended 'evil spirit'.1

?Did Sordes have feathers?

No, it had hair-like filaments called pycnofibres covering its body and wings, not feathers. These helped keep it warm.1

?Where was Sordes discovered?

In Kazakhstan, in the Karabastau Formation from the Late Jurassic period.1

迷思破解王

迷思： Some people think Sordes was a dinosaur because it lived long ago and had a long tail.

真相： Sordes was a pterosaur, a flying reptile, not a dinosaur. Pterosaurs are a separate group of reptiles that lived at the same time as dinosaurs.1
