名字的意思： “grape dragon”1

吃：魚飛行爬蟲類白堊紀晚期嚴格來說不是恐龍

Inabtanin was a flying reptile that lived about 66 million years ago. It had a wingspan as wide as a small car and probably flapped its wings like a bird to fly.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

Inabtanin is one of the most complete pterosaurs ever found in the Afro-Arabia region, which includes parts of Africa and the Arabian Peninsula.1

Its name comes from 'Tal Inab', meaning 'grape hill' in Arabic, because the hill near where it was found looks like a grape.1

Scientists used CT scans to look inside its wing bones and discovered a crisscross pattern of tiny struts, similar to bones of flapping birds today.1 2

Inabtanin lived at the same time and place as the giant pterosaur Arambourgiania, which had a wingspan of about 10 metres (33 feet).1 2

It was a toothless pterosaur, meaning it had a beak with no teeth.1

Inabtanin was a non-azhdarchid azhdarchoid, meaning it was a close relative of the giant azhdarchids but not part of that group.1
