Elanodactylus

名字的意思： “kite finger”1

吃：魚飛行爬蟲類白堊紀早期嚴格來說不是恐龍

Elanodactylus was a pterosaur, a flying reptile that lived during the Early Cretaceous. It had long, slim wings like a kite and a wingspan of about 2.5 metres (8.2 feet). It probably flew over lakes and rivers, scooping up fish to eat.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。

趣味知識

Elanodactylus had neck vertebrae that looked like those of azhdarchids, the giant pterosaurs from the Late Cretaceous. But scientists think these similar neck bones evolved separately in both groups, a case of convergent evolution.1 2

The first bone in its wing finger was shorter than the second and third bones. This is a unique feature that helps identify Elanodactylus.1

Elanodactylus is the largest known member of its group, the archaeopterodactyloids. Its wingspan was about 2.5 metres (8.2 feet).2

The name Elanodactylus comes from the Greek words for 'kite' and 'finger', because its long, thin wings reminded scientists of a kite bird.1

Elanodactylus lived around 125 to 119 million years ago, during the Early Cretaceous period. Its fossils were found in the Yixian Formation in China.3 1

給恐龍專家

學名: Elanodactylus
命名者: Andres and Ji 20083
類群: 飛行爬蟲類
科 / 演化支: Lophocratia3
分類: Pterosauria > Pterodactyloidea3
岩石的年代: 126 到 120 百萬年 (Barremian / Aptian)3
岩層: Yixian3
國家: 中國3
化石紀錄: The Paleobiology Database 收錄 2 筆3
發現: Elanodactylus was named in 2008 by Brian Andres and Ji Qiang. The first fossil, a partial skeleton without a skull, was found in the Sihetun Basin in Liaoning, China.1 2
仍有爭議: Scientists are still debating whether the long neck bones of Elanodactylus evolved for the same reason as in azhdarchids, or if they were used differently.1 2
