Europejara

名字的意思： “Europe + Tapejara, meaning 'Europe's old being'”1

吃：植物飛行爬蟲類白堊紀早期嚴格來說不是恐龍

Europejara was a flying reptile with a big, bony crest on its chin that curved backwards. It lived in what is now Spain during the Early Cretaceous, about 130 to 125 million years ago. This pterosaur had no teeth and probably ate fruits and seeds.2 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

Europejara is the oldest known toothless pterosaur, meaning it had no teeth at all.2

It was the first tapejarid pterosaur ever found in Europe. Before that, tapejarids were only known from China and Brazil.2

Europejara had a strange crest on its lower jaw that curved backwards, which is different from other tapejarids.2

Its wingspan was about 2 to 4 metres (6.6 to 13.1 feet), making it a medium-sized pterosaur.1

The only fossil found is a crushed skull and lower jaw, preserved in fine limestone from an ancient lake.2

Scientists think Europejara may have helped spread early flowering plants by eating their fruits and pooping out the seeds.2

關於 Europejara 最常被問的問題

?How big was Europejara?

It was a small to medium sized pterosaur. Its wingspan was about 2 to 4 metres (6.6 to 13.1 feet).1

?Did Europejara have teeth?

No, it had no teeth. It was the oldest known toothless pterosaur when it was discovered.1 2

?What did Europejara eat?

Scientists think it ate fruits and seeds, based on its toothless beak and the shape of its skull. It might have helped spread early flowering plants.1 2

?Why did Europejara have a crest?

Nobody knows for sure. It might have been used for aerodynamics, keeping cool, or showing off to other pterosaurs.1 2

給恐龍專家

學名: Europejara
命名者: Vullo et al. 20123
類群: 飛行爬蟲類
科 / 演化支: Azhdarchoidea3
分類: Pterosauria > Pterodactyloidea3
岩石的年代: 126 到 121 百萬年 (Barremian)3
岩層: La Huérguina3
國家: 西班牙3
化石紀錄: The Paleobiology Database 收錄 1 筆3
發現: Europejara was named in 2012 by Romain Vullo and colleagues based on a skull found at Las Hoyas in Spain. The name means 'Europe's old being' and honors the ancient Olcades people.1 3
仍有爭議: Scientists are not sure if Europejara was a fruit-eater or an omnivore that also ate insects and small animals. The evidence from its beak shape is not enough to be certain.2
