名字的意思： “play finger”1

吃：魚飛行爬蟲類白堊紀早期嚴格來說不是恐龍

Ludodactylus was a flying reptile with a big head crest and lots of teeth. It lived about 112 million years ago in what is now Brazil. One fossil even has a yucca leaf stuck in its beak!1 4

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

Ludodactylus means 'play finger' because it looked like toy pterosaurs that had both teeth and a head crest, which real scientists thought didn't exist until this fossil was found.1

Its skull was more than 66 centimeters (26 inches) long.1

The only known fossil is a skull with a yucca leaf stuck between its lower jaws. Scientists think the pterosaur got the leaf caught in its beak and maybe died from starvation.1

Ludodactylus had a crest on the back of its skull but no crest on its snout, unlike many other pterosaurs.1

It lived during the Aptian stage of the Early Cretaceous, about 112 million years ago.1 4

The species name L. sibbicki honors paleoartist John Sibbick.1

迷思破解王

迷思： Some people think Ludodactylus is the same as Brasileodactylus.

真相： Scientists now agree Ludodactylus is a different genus, closely related to anhanguerid pterosaurs like Caulkicephalus.1

給恐龍專家

學名: Ludodactylus
命名者: Frey et al. 20034
類群: 飛行爬蟲類
科 / 演化支: Ornithocheiroidea4
分類: Pterosauria > Pterodactyloidea4
岩石的年代: 120 到 113 百萬年 (Aptian)4
岩層: Crato4
國家: 巴西4
化石紀錄: The Paleobiology Database 收錄 1 筆4
發現: Ludodactylus was named by Eberhard Frey and colleagues in 2003 based on a skull found in the Crato Formation of Brazil. The fossil was illegally sold and missing part of the head crest.1 4
仍有爭議: Scientists still debate whether Ludodactylus belongs to the family Anhangueridae or is just outside it, because different studies place it in slightly different groups.1
