Ctenochasma

名字的意思： “comb jaw”1

吃：魚飛行爬蟲類侏羅紀晚期到白堊紀早期嚴格來說不是恐龍

Ctenochasma was a flying reptile with a mouth full of hundreds of long, thin teeth that stuck out like a comb. It used its special beak to scoop up tiny animals from the water, like a spoonbill bird today.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。

酷東西

趣味知識

Ctenochasma had over 400 teeth in adults, all long, thin, and tightly packed together.1

Its teeth stuck outward from the jaws, forming a basket-like shape that helped catch small prey.1

Adult Ctenochasma had a bony crest on top of their skull, but young ones did not.1

Scientists think Ctenochasma was nocturnal, like some seabirds today, based on its eye bones.1

The smallest species, Ctenochasma elegans, had a wingspan of about 1.9 metres (6.2 feet) as an adult.1

Ctenochasma lived during the Late Jurassic period, around 150 to 145 million years ago.1

關於 Ctenochasma 最常被問的問題

?Was Ctenochasma a dinosaur?

No, Ctenochasma was a pterosaur, which is a flying reptile and not a dinosaur.1

?How big was Ctenochasma?

The smallest species, Ctenochasma elegans, had a maximum wingspan of about 1.9 metres (6.2 feet) as an adult.1

?What did Ctenochasma eat?

It used its comb-like teeth to strain small invertebrates from the water, similar to how a spoonbill bird feeds today.1

?Did Ctenochasma have a crest?

Yes, adult Ctenochasma had a bony crest along the skull, but young ones did not.1

給恐龍專家

學名: Ctenochasma
命名者: Meyer 18512
類群: 飛行爬蟲類
科 / 演化支: Lophocratia2
分類: Pterosauria > Pterodactyloidea2
岩石的年代: 149 到 137 百萬年 (Tithonian / Berriasian)2
岩層: Solnhofen, Solnhofener Plattenkalk, Calcaires tâchetés2
國家: 德國, 法國2
化石紀錄: The Paleobiology Database 收錄 7 筆2
發現: German paleontologist Hermann von Meyer named Ctenochasma in 1851, based on a lower jaw full of teeth. He first thought it was a crocodilian, not a pterosaur.1
仍有爭議: Scientists debate whether all the different species of Ctenochasma are really just growth stages of one species, but a 2007 study showed three distinct species based on tooth number and shape.1
