名字的意思： “winged reptile or reptile from Skye in Scottish Gaelic”1

吃：魚飛行爬蟲類侏羅紀中期嚴格來說不是恐龍

Dearc was a flying reptile that lived in the Middle Jurassic, about 167 million years ago. It was one of the biggest flying animals of its time, with wings as wide as a small car! It soared over the lagoons of what is now Scotland.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。

趣味知識

Dearc was not fully grown when it died. It was a juvenile or subadult, still actively growing, so adults might have been even bigger.1 3

Its wingspan was about 2.5 to 3 metres (8 to 10 feet), as wide as a wandering albatross, the largest flying bird today.1

Before Dearc was discovered, scientists thought pterosaurs stayed small until the Cretaceous period. Dearc shows they got big much earlier.1 3

The fossil was found at Brothers' Point on the Isle of Skye in 2017, during a National Geographic-funded field trip.1

Its name comes from Scottish Gaelic and means both 'winged reptile' and 'reptile from Skye', because Skye is called the 'winged isle'.1

Dearc had a long, low skull and a slender upper arm bone, which helped it fly.1

?Is Dearc a dinosaur?
