Cycnorhamphus

名字的意思： “swan beak”1

吃：魚飛行爬蟲類侏羅紀晚期嚴格來說不是恐龍

Cycnorhamphus was a pterosaur, a flying reptile that lived during the Late Jurassic. It had a strange beak with peg-like teeth at the tips and curved jaws that left a gap. Scientists think it might have used its beak to crush hard-shelled animals like mollusks.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

Cycnorhamphus lived about 152 million years ago during the Late Jurassic.1

Its name means 'swan beak' because of the shape of its snout.1

The first fossil was found in Germany in 1855 and named Pterodactylus suevicus by Friedrich August Quenstedt.1

A well-preserved skull nicknamed 'The Painten Pelican' helped scientists understand its unusual jaw.1

Adult Cycnorhamphus had blunter, stouter teeth at the tips of their jaws than juveniles.1

The jaws had a gap behind the teeth, and soft tissue structures filled that gap in the upper jaw.1

Some scientists think Cycnorhamphus used its beak like openbill storks to crush hard invertebrates.1

關於 Cycnorhamphus 最常被問的問題

?How big was Cycnorhamphus?

Cycnorhamphus had a wingspan of about 1.5 metres (4.9 feet).4

?What did Cycnorhamphus eat?

Scientists think it probably ate shellfish, using its beak to crush hard invertebrates like mollusks, similar to openbill storks.1 4

?Why did Cycnorhamphus have a gap in its jaws?

Nobody knows for sure. Ideas include trapping jellyfish, opening seashells, or just for show.4

?Is Cycnorhamphus a dinosaur?

No, Cycnorhamphus is a pterosaur, a flying reptile that lived during the Late Jurassic, not a dinosaur.1

迷思破解王

迷思： Cycnorhamphus had long jaws with many teeth like other pterosaurs.

真相： It actually had short, peg-like teeth only at the tips of its jaws, with a curved gap behind them.1
